USB hub kills laptop

I have a Belkin 4-port USB hub that I plug my external harddrive, ipod, and printer into, which I then connect to my powerbook, all via USB. But, whenever I leave the hub plugged into my laptop and then shut my computer's monitor, putting it to sleep, later, when I open it, it won't wake up. The screen stays black and, though the computer IS on, the monitor won't light up and the only way I can fix this is by rebooting the computer.
I've ascertained that the USB hub has to be the issue because this problem never occurs when I eject all the devices and unplug the hub. Though I know the powerbook has problems with hubs that mix USB 2.0 and 1.1 - that's buried deep in the manual - I have made sure to have only 2.0 devices plugged into the hub, so I know that isn't the issue.
The hub was bought new, as was everything connected to it, so I really doubt that the issue is defective hardware on that end. I would assume that Apple makes their computers so they actually work when USB devices are plugged into them and left there - I use my laptop as my home computer, so it's often in this state - so what's the deal? Apple won't help because it's a third party device that is triggering the problem. The USB hub is the one that Apple sells on their website, so I know it's supported! Any ideas?

Ian, I am not sure if this will help explain about USB connections or not.
USB connections are temperamental and can sometimes cause several different disruptions.
I will give you a few of the anomalies that I am sure USB connections to peripherals can cause. This includes just about any including Camera's Scanners, Printers, and External Zip Drives.
More often than not You need to have the devices plugged in before you start your computer before it can be recognized. This is not always true but it happens, so this is a contradiction, It can work either way but this is the reason they recommend not to disconnect a USB devise while your devise is plugged in. There seems to be a disruption in the connection and if you do unplug it and then plug it back in it will not remount unless you, re- boot, or restart your computer before it will work again and recognize the devise.
It appears that USB devices are normally good in there operation when plugged in directly to your computer, rather then a HUB.
After reading the different posts in these forums on the inconsistency, and from personal experience in there use.
It is know wonder that there is such poor performance in the use of USB Modems, and everyone recommends Ethernet or Firewire connections over USB.
USB is and can be functional, if you remember the simple rules to follow on connection and disconnection of the devises, and special care is taken.
Yes I know we as users feel that we should be able to just plug and play but this is not always the case.

How can I get my iPod Classic to be recognized by my laptop through a usb hub?

My new XPS 13" recognizes my iPhone 4 when run through the 3.0 USB Hub but not the iPod. If I connect thhe iPod directly to the XPS iTunes will recognize the device.

recommended only 2.0 usb.

Laptop not powering off with powered usb hub attached

I have an external powered USB hub which I have attached to my G60 running Windows 7 Home Premium. When I try to shut down the G60 with the hub attached and powered on, the shutdown sequence goes through Logging Off to Shutting Down but never fully powers off. The power and wireless lights stay on and the fan continues to run.
Is there a way around this apart from powering off the USB hub before shutdown?
This question was solved.

Hi @Andrew_c51 ,
I saw your post regarding the problems with your notebook not shutting down all the way when the powered USB hub is connected. It almost sounds like your notebook is going into sleep or hibernation. I would recommend contacting the manufacturers of the powered USB to see if there is a way of stopping this or just disconnect the hub.

USB Hub does not work

I recently purchased this USB hub.
http://www.jascoproducts.com/products/pc/viewPrd.asp?idproduct=8&idcategory=13
My laptop cooler is able to be power through the USB hub.
However, my mouse, keyboard, and external harddrives are not working. For instance, the laser on the optical mouse is not even lighting up.
My mouse, Keyboard, and external hard drive works fine when it is connected directly to the USB pots on my macbook Pro.
Is this a compatibility issue? I mean, GE says that the hub works with mac os. And for a generic hub like this, there shouldn't be any issues right?

Hi wifpck;
The first problem I see with this hub is that it is USB 1.1 which is a very slow out of date protocol.
Secondly it doesn't appear to be a powered hub. Hence all of the power for the hub must come from the USB on your Mac. Powering laptop cooler maybe over loading the USB port. I would suggest that you try it without the laptop cooler connected and see if works better that way.

MacBook Pro (mid-2010) Internal USB HUB freezes/locks up

MacBook Pro (mid-2010) wilth the latest firmware, etc.
OS X 10.9.1
USB KVM to share keyboard and mouse with another computer
This has been working flawlessly until I upgraded to 10.9.1
The KVM uses the Scroll Lock key to toggle the input between the two computers
I switch back and forth many times a day.
Almost once a day now, all my input to my MBP will lock up when switching the KVM over.
The MBP track pad, keyboard, blue tooth Magic Mouse, KVM mouse and keyboard all become unresponsive.
I am assuming that the interal keyboard/track pad/blue tooth transceiver are all tied to an internal USB HUB.
The MBP is up and running and I can ssh into it. The only error message in the log is that the mouse device coming from the KVM is busy and it will be disabled. I have tried to close the lid for several minutes and then re-open, but it does not resolve the issue. I have tried connecting another USB mouse/keyboard during this time and it will not work. I have tried kill -HUP on the usbd and USBAgent processes. Everything stays unresponsive. The only way to resolve this condition is to reboot the MBP. Note: the KVM works find on the other computer when I switch it back and forth regardless of the state of the MBP.
I am suspecting that when this happens it is some how disabling the internal USB HUB, which if all the other devices are connected through it, nothing no longer works (but maybe I am crazy with that thought). Anyone have any insight? Is there a way to reset the internal HUB short of a reboot?
Thanks in advance!

I'm seeing the same problem with a 2010 Mac Mini with IOGear KVM and MS wireless mouse. This setup worked flawlessly for years on Snow Leopard but started hanging soon after the Mavericks upgrade. I'm running 10.9.4, currently the latest release. The system usually hangs after a KVM keyboard switch from Windows on the other set of KVM cables back to the Mac Mini. ssh into OSX works fine but a shutdown hangs indefinitely. top showed no processes spinning. The 1st console message after the hang was:
8/6/14 8:49:21.000 PM kernel[0] USBF: 1317978.201 AppleUSBHubPort: Port 2 of Hub at 0x6200000 about to terminate a busy device (Microsoft® 2.4GHz Transceiver v7.0) after waiting 10 seconds
There were no other messages for hours before this. I'm using VM Fusion but I think it hung once without it running. The Windows 7 side of the KVM works fine.

Why do USB drives plugged into USB hubs make my Mac Book Pro (Retina late 2013) wake from sleep?

I have 2 x USB hubs, a Logitech USB 2.0 hub and a Broway USB 3.0 hub. Tested both and both seem to be the cause of my late 2013 Mac Book Pro waking from sleep. I ran syslog to find out why (syslog |grep -i "Wake reason") and the reason I got back was "kernel[0] <Notice>: Wake reason: XHC1" - this means nothing to me, but it didn't take too much mucking about to hunt the problem down and figure out it was the USB hub with any USB drive attached. If the drive is attached directly to the computer. No problem, computer sleeps fine.
This was a problem I encountered (and never solved) with OSX 10.6.8, a 2008 Macbook Pro the same Logitech USB 2.0 hub, but with different drives. I put the problem down to a bug that never got solved in an old system. But I am simply AMAZED after my update to a new MBP and new system that it is still about almost 6 years, a dozen MBP's and 4 systems later.
The other problem is that not only does the USB drive/ USB hub combo wake the computer it also loses the drive upon sleep and mounts it again upon wake. Then repeats this process every couple of minutes. And it obviously doesn't eject the drives properly because each time I return to the computer after I put it to sleep or let it go to sleep I get a giant list of "Disk Not Ejected Properly" notifications about it. Which I'm guessing could eventually cause some file damage.
I've tried combinations of different drives, different hubs (a Belkin and a no-name Chinese brand 2.0 hub) and the problem persists. Is there a solve to this problem? I'm surprised to see so little posts on forums about this. Am I just unlucky and got another combination of faulty/problematic hardware, or is this a real problem that exists for everyone? If not I would love to know if people have found winning combos of USB hubs and drives. But if it is, then it HAS to be solved.
If you have a Macbook Pro, then you are limited to 2 USB outlets, this is obviously a bare minimum and I would say that 95% of people using their laptop computer in the office or at home have a hub, and very likely a USB drive attached to it. I know actual Apple reps don't really pay much attention to the community support posts, but I've got 6 months worth of Applecare left and would like suggestions about how to get Apple's attention about this problem.
BTW Jettison (a 3rd party app that ejects drives properly before sleep) is not a solve. It is a 3rd party app that tries to fill a hole in a broken system. I don't want to eject my drive upon sleep, I want it to got the **** to sleep.

Is there a pattern to the time of day or other detail that may be
traced back to a OS X system cause of this odd phenomenon?
Are there any copies of system files on any of the attached USB
external drives? Any libraries, such as iTunes, iPhoto, etc?
Once the drives are indexed by Spotlight, are their permissions
ignored by the OS X? Content, if neutral, should not affect the
wake or sleep cycle; especially if they're ignored by the OS X.
Could there be a bad cable or other component? If so that would
be a difficult process of elimination to detect it. Usually replacing
most suspect components in the USB stream (external to Macs)
is a rote way to mechanically test that idea; & not 100% sure.
Does the equipment all have a good ground to the utility or house
electrical field? An intermittent ground may affect more than sleep.
Hard to say at this point. Maybe a late-night talk radio guru on
remote viewing could peer into your situation and sleuth it out?
Sorry to have run out of ideas, but the process must be electrical
& mechanical to some extent. - Or perhaps odd software inspired.
Do you have any phone-home spyware items inside, just jumping
at the chance to spill your information? Little Snitch may help.
PS: Perhaps the computer needs to go into Apple & have a genius
or product specialist at AASP test the unit thoroughly... BlueTooth?

External Drive won't show up when connected to Airport via USB Hub

I just got a new external HD and hooked it up out of the box. There were no problems until I tried copying 117 files to it. An error was encountered (Couldn't complete command due to something or other) and after that I never showed up on my computer again. I tried rebooting... hooking it up directly to the computer...the whole bit. Nothing.
So I then hooked it up to our laptop. It was found, I erased it, hooked it up to the desktop... it was found there as well... but whenever I hook it up wirelessly via the USB Hub and Airport... I can't get it.
Everything else that's hooked up to the hub is still working wirelessly (Printer Internet).
Is this an isssue with the drive?

Ya' know.. I'm not totally sure. I went to Airport Utility... selected my base station, clicked on Manual Setup... clicked on Disks and saw that my USB Drive was listed. After that I opened the finder, went to network, connected to my base station from there and my USB Drive popped up and I mounted it.
It's been working fine since.

Can i connect to a 'belkin USB Hub' so i can print and save images direct from my ipad 2..

I have just bought a 'Belkin USB Hub' so that i can have my printer and external hard drive in a home office rather than carting them around the house or having to sit in my back room when i want to print from my mac lap top, works fine , but my question is, is it possible to connect my ipad 2 to the hub so i can edit and print directly from that rather than having to re-sync to my laptop.

The only solution to enable printing with the iPad is via WiFi or by using one of the HP AirPrint compatible printers.

If you don't own of these printers you will need a third party app that will allow you to print. Print n Share, Print Central, and others are available in the App Store. Some of these apps will work only if your computer is turned on and may need a helper app for the computer as well. if you have a Mac you can use Printopia. The computer must be on for this app as well. Print Magic has been mentioned on this site a few times. Google or check the App Store.

Macbook Pro freezes when I unplug USB hub

When I unplug my USB hub from my Macbook Pro it freezes up and I have to turn it off and back on. I did not have this problem before, it just starting happening recently. The only thing plugged into the hub at the moment is my keyboard which has the wireless reciever for my mouse plugged into it. Any solutions would be greatly appreciated as this makes it a hassle to take my Macbook anywhere.
The USB hub is Gigaware brand, my keyboard is Apple, and my mouse is a Logitech MX Revolution, if that helps. I also have a LaCie 1tb external hard drive plugged in but that's using the firewire 800 slot so I wouldn't think that would affect it.

I have a somewhat similar problem with my Macbook Pro and USB hub - it just started happening last week as well. I have a USB (external power) hub that hooks to an audio interface, piano keyboard, wireless keyboard and mouse. I normally have my laptop off when I hook up the hub because I've been traveling. Last week I plugged it in while the computer was on and the hub froze. I turned off the computer and unplugged everything. I turned everything back on and the hub worked...for a few minutes. Now anytime I run any type of audio or video from the computer (itunes, LogicPro, internet video) the hub freezes as soon as I press play. Then the program (like Itunes) freezes and I have to force quit. This makes me wonder if it is not the hub but something that the computer is using to run audio and video. None of my external equipment has caused problems for a year now - there is no new equipment - and just the standard Mac software updates.

Mount USB Ext drive that is connected to Airport Ext base sta via usb hub

My Lacie drive disappeared from the desktop after downloading a recent Mac software update. It is connected to my compter wirelessly via a usb hub connected to AirportExtreme Base Station. The only way to get it back on the desk top is to connect it directly to either th Airport base station or the laptop without going through the hub. I've tried different hubs and none works. However, all of the support the printer wirelessly. Is there another usb drive out there that works? I'm ready to dump the Lacie.

Make sure your lacie firmware is up to date as well....I dont know which drive you have but you can visit http://www.lacie.com/us/support/drivers/index.htm?id=10007 to see what the latest firmware downloads are for your drive. I have an Ethernet Disk mini v2 (Gigabit) and firmware update solved access issues.

Attach Ethernet dongle via USB hub?

Hi. I'm getting a new MBA at work and the only reservation I have is the single USB port. Can the Ethernet dongle be plugged into a USB hub, or does it have to go straight into the port on the laptop? Does i tmatter if the hub is powered or not?
Thanks for any help.

You should be able to use the USB Ethernet adapter on a USB hub. The hub needs to be USB2 (not the slower USB1.) I don't know if the hub needs to be powered or not, but in the past, I've had trouble with non-Apple USB Ethernet adapters on non-powered hubs. [This thread from a few days ago|http://discussions.apple.com/thread.jspa?threadID=2497134&tstart=0] was from someone with issues using the adapter with a hub, although he has not posted his final results yet.
If you can't find a compatible hub, perhaps you can use a Wi-Fi access point. It's like a typical home router, but just the wireless part. In essence you'll have a "wireless" ethernet adapter for your Macbook Air, instead of a USB adapter. Some companies internal policies do not allow wireless networking so you may have to check with your network administrator.
Some consumer home routers can be configured as an access point (a.k.a. bridged.) If you don't need to take the "ethernet adapter" with you on the road, then you can just get a non-portable access point. Otherwise something like an [Airport Express|http://store.apple.com/us/product/MB321LL/A/AirPort-Express-AirTunes?fn ode=MTY1NDEyMQ&mco=MTA4NzI4ODU]. Other companies have similar products. I used the [dLink DWL-G730AP] in my pre-Macbook days. I believe dLink has [a faster one now|http://www.dlink.com/products/?pid=753].

Multiple Printers off USB Hub

I run a complete variety of macs as a home network and am thinking of buying a new Airport principally so that I can use it as a server hub with the external drives I have (holding backups, photos, music etc).
I'm quite happy setting up the network (mixed wire and wireless) but am wondering if I can run multiple USB drives and multiple printers (colour and cheap laser).
If I place these in one location running a powered usb hub, will all the drive show up ? and If they are switched on, will all the printers show up as available ?
Any helpful hints, I'm looking to hide backup drives and printers leaving a minimal desktop and laptop footprint.
(PS buying new macbook soon to get the speed benefit from AE, but the network disk/printer is what interests me most)

Airport Extreme REQUIRES powered USB hub for external HDDs

Just bought an Airport Extreme Wireless dual-band N router (January 2012). It works very well and having the separate 2.5 and 5 GHz bands is a fantastic feature. Setup was really easy and it essentially worked 'out of the box'. The one issue I had is attaching a USB Western Digital 1 TB HDD to share on the network and use for Time Machine backups from multiple MacBook Pro laptops.
The drive would appear in the Aiport Utility's "Share Hard Drive" tab, but it was listed as zero bytes and wasn't available to actually share out over the network. I formatted it as a single volume to make sure there wasn't an issue with the drive itself (although it should support multiple partitions on a drive), and it mounted to my Mac just fine, but it still would not work with the Airport Extreme.
After reading several posts on these Apple forums I picked up the fact that the only way most people get their hard drives to work is by purchasing a powered USB hub and connecting that between the Extreme and the hard drive. Some hard drives do appear to work plugged directly into the Airport Extreme, but that seems to be more of the exception than the rule.
The reason given is that the USB port on the Airport Extreme was originally designed for printers and is basically underpowered for proper HDD connections. Adding a powered USB hub not only allows USB hard drives to work, but you can connect multiple USB devices (hard drives and printers) to share over the Airport Extreme through the powered hub, so you do get that added feature.
So if you have plans to upgrade to the incredibly fast and efficient Airport Extreme and plan to do your Time Machine Backups wirelessly (which works very well), add a powered USB hub to your purchase to avoid some frustration. I picked up a four-port powered USB hub at Staples for $30.
It's a great purchase otherwise. Four out of five stars in my review.

For anyone else who reads this post, the respondents are correct. I cannot find anything directly from Apple that states explicity the support for Time Machine backups to a USB drive on a second generation Apple Airport Extreme. I would love to see their detailed case studies and latest tests that demonstrate the backup corruption isues, and more recent tests conducted with the latest Airport Extreme, running the latest firmware with Lion 10.7.2.
Having said that, each person who is interested in this as a backup solution should consider more than one source before making a final decision:

http://news.softpedia.com/news/Time-Machine-Update-Back-Up-on-AirPort-Extreme-Ad ded-81256.shtml
The Apple Support articles referenced that explicity state TS does not work with Airport Extreme mounted USB drives are for older OS X 10.5 and 10.6. I cannot find anything for 10.7 that states the same thing:
Older Mac OS X 10.5 and 10.6:
http://support.apple.com/kb/HT2038
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
http://Pondini.org/TM/Airport.html
The other thing you can do is on the Time Machine menu, hold down the "Option" key and use the 'verify backups' option to help ensure that your TS backups are valid.
Hopefully Apple will come out with an official statement soon that speaks directly to the 2nd generation Airport Extreme on the latest firmware running TS backups from OS X Lion 10.7.
My statement about the need for a powered USB hub to have much better success with USB attached hard drives still stands.

Cannot get the 5.1 Multimedia Centre Audio/USB Hub working

Hi there,
I wonder if anyone could help save my sanity...
I have been using a Toshiba Tecra A8 laptop now for sometime with no problems. This is running with Windows XP. I love it, its great, all except for one thing.
I REALLY miss my Creative 5.1 speakers for listening to music to in my box room when working from home.
They just sort of sit there on the windowsill, pining to be used....
So, I thought to myself, there MUST be a 5.1 USB external soundcard that I could purchase to allow these speakers to be operational once again. Imagine my surprise when I discovered that Toshiba themselves made such a thing!!!
In my simple way, I believed that it must be the best solution, to purchase an accessory of the same manufacturer as the machine itself.
This would be a doddle and I would once again be listening to quality top end and punching bass......WRONG!!!
I have now installed and uninstaled the software 3 times.
The thing works lovely as an additional USB hub, perfect, no probs at all, but try to get a single note of music from the thing? Forget it!!!!
I can get sound from the laptops speakers when the usb lead is not connected in.
Everytime I do connect the multimedia (?) centre to the laptop I get the "Found new hardware" wizard come up & I am too simple to be able to simply tell the damn thing where the files that are now necessary might be.
So, I ask for all of your powers to solve this before I load the laptop, the speakers, the multimedia (?) into the car and head off to Toshiba HQ in Addlestone to demand satisfaction.
Many thanks for anything you can do to help me hear sound through these speakers once again.
Soulster

About Multimedia Centre Audio, I have no idea.
1. May be damaged USB 4 port mini hub itself lead to
2.USB Interface Damage
3. Chassis front interface, leading to voltage instability
4. Used to extend the line leading to insufficient power supply to USB 4 port hub Interface Device Not Recognized
*Recommendations directly to the device plugged into the USB port on the back-end chassis (without extension)
5. There is also a very important factor! Now USB, anyone can produce, it is clear there will be a problem, is not compatible with the system, more terrible thing is that these parallel imports please some of the manufacturers rookie programmers to write some of the junk drive and cause problems by virtue by virtue (such as something very popular in China)! So, bought brand on all right!
6. It is possible that the wrong front USB access, and perhaps pick the wrong chip burned
7. Motherboard BIOS settings

Airport Extreme, Belkin USB Hub, and external hard drive

I'm having a serious meltdown. I've been at this all day long and I've reviewed SEVERAL, if not all, discussion threads. I've seen my question many times on many threads, but yet to find a solution!
Just got the hub, and I tried today to connect the Belkin USB hub so I could get my external hard drive accessible from my Mac. My external drive worked fine on my PC. I recently moved to Mac.
Printer works with no issue at all, but my external drive does not even list in either the Disk Utility or System Profiler. It just doesn't get recognized. I've tried EVERYTHING...switching ports, connecting directly to my Macbook, restarting, etc., etc., etc. NOTHING.
Anyone have any insight to this? I'm ready to throw in the towel.

Ok I'll try that! Uh oh...now I can't even see the external drive on my PC! I also spent some time looking at the manufacturer's website to see if there's any software I may have downloaded before using the hard drive, but the website is not helpful in that capacity (www.cavalrystorage.com). I don't remember having software when I first started using it. Furthermore, I just looked at paperwork I received when I got the drive back in Nov.06 and it says not to use "the CD if you have Windows", (to install a driver, perhaps?) which of course, I did. But now I can't find what disc I may have gotten with the drive. It also had no specific instructions for a Mac. Although the external drive has wonderful reviews, and says you can use it with a PC or Mac. I hope this helps. I certainly appreciate your help!
I'm starting to think something has gone awry with the external hard drive? I've tried connecting through the hub (my printer works at least!), direct to AirPort, and direct to laptop and nothing.
