USB hub issues

I'm not sure exactly when this started happening but I ran out of usb ports so I purchased a usb hub. Now every time I shut down my iMac it appears to go off but when I try to turn it on the next morning and I push the power button, nothing happens. I have to hold the power button in for 10-15 seconds (to completely power it off I'm assuming) and then when I push power again it boots up. I've also had connection problems with devices running through the hub. I've replaced the hub with a brand new powered hub and I have the same problems. If I plug the devices directly into the iMac it works fine, I just don't have enough ports. Is this a hub problem or an OSX problem with usb hubs? I don't remember having this problem pre-Leopard.

Since I've posted this, I've noticed if I unplug my hub before shutting down, at next bootup it boots up fine.
Devices plugged into hub:
MS Intellimouse Explorer
USB Extension cable (for flash drives)
USB Cable for digital camera
hp Scanjet 4370
The hub is a Cyberpower 7 port hub CP-H720P with power adapter.
The 3 ports on my iMac are:
Canon ip6000d printer
LaCie External 320gb hard drive
Cable to USB hub
The three ports on the mac are always plugged in. I stated above that I unplugged the usb hub before shutting down last night and it booted up fine this morning. This leads me to believe OSX is still powering the hub which is why it doesn't shutdown all the way. When I went from Tiger to Leopard I did an upgrade not a fresh load, I'm thinking that might be the next step.

IPad 2 iOS 5 Windows 7 USB hub issue solution

I thought I would post this message to help those running Windows 7 (or other versions of Windows) that might be having "USB Device Unrecognized" issues with their iPad when going to iOS 5. In my case it is an iPad 2.
Long story short... When upgrading to iOS 5 using iTunes 10.5, if you are getting "USB Device Unrecognized" error messages or Windows has trouble installing the USB driver with your iPad (or maybe another iDevice) and that device is connected to a USB hub of some sort that may have worked previously under iOS 4.x or earlier, the solution for me was to connect the iPad to one of my PC's main USB ports (as in the ones directly connected to the motherboard). For whatever reason, Windows is not able to recognize my iPad 2 running the first release version of iOS 5 when it is connected to the USB ports on my Dell 2408 LCD panel's hub. Even though this was never an issue with iOS 4.x
More detail...
I am running Windows 7 (64 bit) with all the latest updates and I had an iPad 2 running iOS 4.3.5 and I always docked it and my iPhone 4 to my PC using the USB hub on my Dell 2408 LCD panel. I NEVER had any USB issues with either device until going to iTunes 10.5 & iOS 5.
The issue came up when I was doing a restore of the iOS 5 GM (which is the same as the final release of iOS 5) to my iPad 2. When I started the restore, the iPad 2 gets reset to DFU mode (or whatever mode it gets in to start the restore) and at that point Windows complained about the USB Device being unrecognized. After I gave up I told iTunes to do a regular restore back to the previous version (4.3.5) and Windows had no issues seeing my iPad and doing the restore connected to the same USB port.
So there appeared to be something about iTunes 10.5 or iOS 5 causes Windows to not be able to install the correct driver and have "USB Device Unrecognized" errors when my iPad 2 was connected to my Dell monitors USB hub. I should mention that my iPhone 4 running iOS 5 has no problems being connected to my Dell monitors USB hub. I tried all the suggestions that Apple has on their support section. Restarting the Apple Mobile Device service, Uninstalling the bad USB device under the Device Manager in Windows and rescanning for devices, un-installing and then reinstalling iTunes 10.5 and the other Apple software etc... etc... Windows still could not find the correct USB driver and couldn't recognize the device. Nothing worked or when it did it only lasted for a very short time. One of the 4 ports on my Dell finally installed the correct drivers but then it stopped working.
The solution was for me to use the built in USB ports that are on my PC itself. After I did that, Windows has no issues installing the proper driver for my iPad 2 and seeing it once I used the PC's USB ports.

Yes, Apple has caused people to go through massive panic, anxiety and wasted time by not coming out and telling us about this problem. They must know about it. How can we tell them? Now I understand why it took me 50 tries to upgrade to OS5. We all got the same crazy errors that caused us to reinstall iTunes, turn off our firewalls, buy new USB cables and basically waste tons of time and energy, when the solution was very simple. Plug your device into a USB port on your computer.
After years of using a peripheral USB hub successfully it's no wonder we all started freaking out and thinking it was a major problem. Yes, I'm blowing off some steam, but I've been an Apple fanatic for a long time and I'm not happy about their lack of response to this issue.

Yosemite 10.10.2 and USB hub issue

Hi there,
I got a MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite last December and bought a USB hub (four-port) on Jan 3rd. I was using it for one month with
OS X Yosemite 10.10.1 without any problems.
On Feb 4th I switch to OS X Yosemite 10.10.2 and I started to have 2-4 times the following issue per day:
- mac frozen (I cannot use the keyboard or the mouse) but I see that the clock is working. No other way that a hard reset.
I did check memory and hard drive and everything is ok
- for one week I did use the USB hub and didn't have any issue
- I started again and less than 24h hour later I got a similar issue !
I am not 100% sure this related to 10.10.2 but before with 10.10.1 I had no issue ! I am not sure to understand how a USB hub can crash a Mac.
I try to look a the Consol application but couldn't really identify a common issue a the time of the issue but maybe some messages like that :
Any idea or suggestion ?
Thanks

DELL 2713 USB hub Issue on MacBook Pro Retina 15

Hello,
I have a new MacBook pro retina 15" and Dell 2713 monitor.
the Dell works fine with the MacBook with supplied DP cable.
BUT the USB hub doesn't work, the monitor is connected to the computer with original dell usb 3.0 cable.
Note: on PC & win7, it works fine
How can I find a proper drivers for this built-in USB 3.0 hub.
thanks,
Tomer

The Retina models are full of flaws. You have found one of them. For some reason the discrete graphic card is being shut off in Windows and you are now using the built in Intel HD Graphics 4000. Why I have no idea.

Sun Ray 2 - Connecting to monitor with USB Hub issues

Hi,
We recently purchased 21 Sun Ray 2 devices and 21 Dell 1909W monitors with built in USB ports to go with them.
This combination works great with 17 of the Sun Ray 2 devices, i.e. mouse and keyboard connected to USB ports on monitor then A to B USB cable running from Sun Ray 2 to Dell monitor.
However, on 4 of the setups this combination fails to work, and after troubleshooting we identified neither the Sun Ray 2 or Dell monitors were faulty. Our support agents suggested since Dell could use a different USB hub 'engine' for their monitors (Even the same model of monitor) this may cause problems being picked up by the Sun Ray 2 devices.
After trying out a box of spare A to B USB cables we had lying around spare, surprisingly 3 of the 4 before non working devices are now working. However, if the 'magic' leads were to be stolen etc we would have a problem again!
Are there any sorts of firmware updates etc for the Sun Ray 2 devices that would mean we could get all the monitors working with the standard Dell provided A to B USB cables? At the moment the optical light on the mouse will 'blink' and then nothing else will happen (It does 'blink' on the working setups before getting full power).
Many thanks :)

no I tried with bro's iPod which have 4.x firmaware and it works fine. So I guess it's safe to assume this is problem because of firmware

USB 3.0 Hub Issue with W510 Please Help

I tried to search for this but no luck. I just bought a Syba 4-port USB 3.0 hub to use with my W510. After plugging in the power and then the USB cord, the drivers installed and everything seemed fine. After restarting the computer I noticed that I had lost Bluetooth (even the LED was off). I tried restarting again and using the Function-F5 keys but Bluetooth wasn't even an option. I disconnected the hub, restarted the computer, and was able to see and reenable Bluetooth. I repeated the problem, and now have resorted to hooking up the hub to my desktop. To make sure it wasn't a "hub" issue I tried a USB 2.0 hub with the laptop and it booted up just fine, with Bluetooth still enabled. Also, while I didn't confirm it, somehow I think plugging the Syba hub in (AC adapter) and then inserting the USB cable actually turned my computer on...weird. Does anyone know why this USB 3.0 hub won't let my computer boot normally? Can anyone recommend a USB 3.0 hub that can be left plugged in and doesn't have any boot or Bluetooth issues? I couldn't find a BIOS setting that might be the culprit.

There appears to be a BIOS bug with the latest BIOS (1.34 for my 4318 CTO W510). After the above failed attempt to hook up a USB 3.0 Hub I tried a different brand (Monoprice) and had exactly the same result. You can't have a hub (with AC Adapter attached or not) to my laptop without it disabling Bluetooth at bootup (the radio is unavailable in Windows until you unplug the hub, restart the computer, and reenable with Function F5). I've elevated the issue to Lenovo and hopefully they'll have a BIOS update...it isn't a driver issue (I don't think) as the Bluetooth gets disabled prior to Windows booting. Has anyone else successfully been able to get a USB 3.0 hub to work, while mainting Bluetooth? By work...I mean not having to plug and unplug everytime...you should be able to leave it plugged in, turn off the computer, turn on the computer, and everything still work. Frustrating.

Printing issues via a Belkin USB hub to a Samsung ML-2240

Hello All,
I am trying to help a friend of mine setup wireless printing from her Macbook. Unfortunately I don’t know very much about Macs and OSX but I am a quick learner
The setup:
Virgin Media Cable Modem -> connected (RJ45) to a Wireless Linksys Cable Modem -> connected (RJ45) to a Belkin USB Hub.
From the USB hub I have two printers connected:
1 x HP Deskjet
1 x Samsung ML-2240 Laserjet
Both these printers install to the Macbook perfectly as default USB devices (wirelessly) via the USB Hub. They also appear correctly in the Belkin USB Hub software console.
The HP printer works perfectly every time it is used, no issues whatsoever. The Samsung printer prints ok the first time but the print jobs do not disappear from the print queue on the Macbook, the print job doesn’t appear to complete even though it has actually printed without any issue.
The problem this causes is that after the first print job has been printed it is not possible to print again. Even if I delete the print job from the queue manually I cannot still not print a second time. The only way I can get the printer to print again is to unplug and then plug back in the USB cable that is connected to the USB Hub. When I unplug the cable the print job disappears from the queue on the Macbook. I can then reconnect the USB cable and connect to the printer and it will print again.
I have made sure that I have the latest firmware on the Macbook which is running 10.5.* OSX. I have also installed the latest Firmware and Drivers on the Samsung Printer and the USB Hub.
Is there a different way to setup the print queue that you think may help? Any ideas would be greatly appreciated. I spent 5 hours on this yesterday and it still isn’t working
Thanks
M

Further info:
- it appears that the firmware version is 5.7 on this AirPort Extreme
- when I plug in my other printer (Samsung ML-1710), it appears in the list of USB printers in AirPort Utility.
- unfortunately, the ML-1710 is no longer supported in Snow Leopard
- under Printer Setup, Driver, I selected Generic PCL Laser Printer for the ML-1710 as a test - the print queue opened, my printer did its "about to print sound", the print queue told me the job had printed, but nothing came out (yes there was paper )
- found the entry below (from Neptune78 on http://discussions.apple.com/thread.jspa?messageID=10067336&#10067336) re. driver for ML-1710, followed steps successfully until the final printing part when the printer stalls and pauses @ 10% printing stage
Any help appreciated

USB port issues (hub, EyeTV Hybrid, speakers)

Balky USB ports continue to be a problem with me. Not to get off subject, but I had a horrible time with my old iBook that one day decided it didn't like to recognize my iPod Shuffle.
Now I've got a new MBP that doesn't seem to want to play nice with my Kensington USB pocket hub, Altec Lansing XT1 speakers and, particularly, an EyeTV Hybrid that worked great at install and ever since has shown as No Device Found.
I've tried restarting, plugging in devices in various sequences, resetting PRAM and performing an exorcism. I can get the speakers to work, and the hub with some effort. But I can't get the EyeTV Hybrid to make an encore appearance to save my life.
Thoughts?

My USB hub does have external power, but the issue with the EyeTV Hybrid continues regardless of whether it is connected to the hub or directly to either of the computer's two USB ports.
I'm tempted to think I just need to replace the EyeTV unit, but I have had so many problems with Apple USB ports, I thought somebody out there might have found some solutions. They have been extraordinarily finicky about what they play nice with, it seems to me.

Issue: USB HUB displaying corrupt drive Icons

Hello everyone,
On my new computer (Windows PRO 8.1 64 Bit, Intel X99 (i7-5960X CPU)) I decided to install a 3.0 USB HUB. The HUB is a EXSYS EX-1181 10-port USB 3.0 HUB. In my initial configuration of my computer, my wireless headphone (LOGITECH wireless G930 Headset) signal
receiver was connected to the HUB as well as other USB keys. Little did I know that for proper use of my wireless headphones, the wireless signal receiver had to be connected
directly onto the computer and not indirectly like via a USB HUB port. Upon correction of the problem, my headphones worked properly.
However the fact that I plugged the headphones wireless signal receiver onto the HUB somehow corrupted the USB HUB. Now, whenever I plug a drive (USB stick, external hard drive, Ipod,...) onto the HUB, my computer always shows the connected drive with an
icon corresponding exactly to the headphones. No matter which port I use and no matter what I connect to the HUB, the drive will always have a Headset Icon on Windows Explorer and not the standard drive icon image.
Could anyone please help me with this issue?
Thank you a lot,
Best,
Marth 286

Mega PC issue with usb hub

I have an MSI Mega PC with the following config:
2.66GHz P4 533Mhz FSB CPU
2x512MB PC2700 DDR
160GB Maxtor 7200RPM IDE Drive
ATI Radeon 7500 All-In-Wonder
TDK 440N DVD±R/RW drive
Windows XP Pro SP1a
I have a ton of USB peripherals
Linksys USB Wirless Ethernet
ATI Wireless Receiver
Western Digital 80GB External Drive
Epson Scanner
Epson Printer
Veo Webcam
Canon S400 Digital Camera hookup
To support the additional peripherals, I added a powered USB 2.0 hub to the rear of the system. This worked for a week but then the card readers in the front no longer were recognized by the system. Also the boot up into Windows would take 3-4 minutes where it used to take less than 30 seconds. Under the Device manager, one of the USB controllers has a yellow exclamation mark that I could not get rid of.
I can alleviate these problems if I hook up the hub to one of the front usb ports instead of the back. This is ok though I would rather have the usb hub connected to the back for aesthetic reasons. Anybody know why there would be a problem hooking a usb hub to the back?

The most likely problem is the cable or USB connector. First, try another USB port, preferably in the back of your PC, and not on an external hub. Next get another cable.

USB HUB connection issues

I recently added a D-LINK DUB-H7 to my macbook.. The usb hub works fine when my macbook pro starts up but after the laptop goes into sleep mode I will experience either problems with a few of the devices connected not responding or all of the devices not responding. The only solution seems to be a reboot of my macbook pro.
Does anyone know if this problem is Mavericks related or if there is something I can do within the system to prevent the connection from being lost when waking my Mac from sleep mode?

I was having the same problem with my USB hub after connecting an audio interface that used up one of my USB ports on my MacBook Pro. I connected the hub to the other computer port. That's when all the trouble started with trying to come out of sleep mode.
My solution was to connect my keyboard directly to the computer port and then daisy chain the hub out of the USB port on the keyboard. It seems that you need to have your input devices on the first part of the chain.
I hope that's helpful
Cheers.

Compatibility issue with USB Hub?

I have a Toshiba Satellite A505 laptop. I added a Rocketfish 4 USB Hub and started having problems. Now when I put my laptop into SLEEP mode, about half the time when I try to wake it, it's unresponsive. I've tried all kinds of things, but the only way I can get the screen back on is to unplug the USB Hub. Thoughts?

There are FireWire printers, but these tend to be expensive specialized printers, like large format printers. Most consumer printers these days are USB.
There are FireWire flash drives
http://www.kanguru.com/fireflash.html
But they are expensive compared to USB flash drives. There are also FireWire memory card readers, but again, more expensive. In your case, if you really need a high-speed flash drive, you have to get a FireWire flash drive because your iMac USB 1.1 ports are so slow. You can even boot your Mac from it, if it's big enough to hold the OS. For people with USB 2.0, it's much cheaper and almost as fast as FireWire to get a USB flash drive.
I don't know of any FireWire input devices (keyboard, mouse, etc.).
USB hubs are pretty cheap, even the powered ones. This one from Belkin is only about $20 after the $10 rebate (and it has seven ports).

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?
Message was edited by: wlfpck

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.

USB hub does not work with iTunes

I have been trying to add USB ports to may Mac's and am not able to synch through the hub. They are hi speed 2.0 USB hubs by Rocketfish and Belkin. iTunes locks up until I remove them from the USB cable (spinning color wheel) and then iTunes goes back to normal. I have tried with both my 24" Intel iMac (Metal one) and a new 15" Macbook Pro. When I use the USB port on the Mac iTunes works great. There seem to be a ton of USB problems posted and zero answers on how to correct. I have tried with an Color iPOD, iPhone and an iTouch to no avail. Having a couple of USB ports won't work in my situation. Anyone know if Apple has posted a workaround or a real fix anywhere.

Thanks, I missed where I posted But I tried with my HP - Same issue. I think others have had this. I believe that iTunes is hit or miss on Hubs. I wish I could figure out what makes them a hit - instead of a miss.

30'' Cinema Display with mini-display-port to dual link DVI adapter usb hub

Hi all, I don't know if any one of you experience this issue and can help me.
I am using an unibody macbook pro (late2008 model) to connect to a 30'' cinema display via the famous $100 mini diaplay port to dual link DVI adapter. I have connected the usb cable from the ACD to the adapter and the usb cable of the adapter to my macbook pro. This setting works fine under OSX 10.5.7.
When I am using Windows Vista under bootcamp the USB hub on the back of the ACD doesn't work. The device manager of Vista shows an excalmatory mark besides the device "Generic usb hub"; and it reports a problem of "the device cannot be started".
I doubted this problem is due to Windows cannot recognise the $100 adapter as a "generic usb hub"; and apple has not release a driver for this $100 adapter for windows.
Since my MBP only has 2 usb ports and the $100 adapter already occupied one, it would be very much helpful if the usb hub of the ACD can work just like in OSX. Can anyone think of any suggestion?
Much appreciated for reading this post and thank you.

i don't have an answer for you, but i feel your pain. very frustrating when this happens with Apple products and Vista/Bootcamp. wish they were more compatible, for it would make things so much easier for the consumer.
