USB Hub

I purchased a targus 7-port USB hub for my powerbook, but in about 30 minutes of it being plugged in, I get increasing background noise from the fan that then gradually becomes even more increasing to annoying limits and prevents any work from being done.
Can you suggest a powerbook friendly hub?
Thanks

USB 2.0 hubs and devices increase the PB's fan activity. For connecting low speed devices, use a 1.1 hub. If you need an external hard disk, better choose a Firewire or a Combo drive.

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The first problem I see with this hub is that it is USB 1.1 which is a very slow out of date protocol.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.

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.

USB hub does not work! Help

I was attempting to install a KVM switch for my G4 and G5 that required me attaching my keyboard and mouse to the usb port on the back of the monitor.
The USB hub does not work! Monitor cable has no bent pins, and works perfectly for video with all my Mac's, G4's, G5's. The problem is I have had this monitor awhile and never tried these ports so apple won't help.
Anyone have any suggestions why these ports don't work and if there is a fix?
Can any one recommend a KVM switch that supports ADC, and USB so I bypass this hub.
Thanks

Some USB 2.0 hardware works very well w/USB 3.0 & some don't. Suggest that you contact the sound card manufacturer & ask them. Perhaps they can recommend a work-a-round.
Another user posted about the same problem some weeks ago regarding a sound card.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not. I've tried several USB connectors, and several different ports on my USB hub; same result. I need to have the HP connected to the hub 'cause from there it's connected to our desktop Mac.

Hi,
I am currently replying to this as it shows in the iChat Community.
I have asked the Hosts to move it to Snow Leopard (you should not lose contact with it through any email links you get)
I also don't do Wirelss printing so I can't actaully help either.

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.

Time capsule doesn't see printer through USB hub

I can't seem to get the TC to see my USB printer if it connects through a hub. I have an external drive plugged into the hub and I can plug it into any of the ports and the TC log file shows the disk plug in and unplug. The disk works great.
So far, the only way I've been able to print via the TC, is to connect the USB cable direct to the TC. But there's no indication in the AirPort utility that the printer even exists. Using System Preferences printer setup, I'm able to see the printer, add it and print a test page. At no time did the AirPort utility indicate that the printer was indeed attached to the Time Capsule and functioning correctly.
How do I get the AirPort to give me more log information? I can't believe that I'm able to print via the TC, yet the printers pane is empty, and nothing in the system log.
After doing this test, I again tried using the hub, and the printer is no longer visible on the Mac, but the disk on the hub is there. I unplug the hub and plug the printer direct, and it's again visible on the Mac. At no time does the TC indicate that the printer exists.
I do Linux system admin all day and bought a mac because it runs Unix for command line, and is supposed to be a "no brainer" to manage - a big plus as I really don't want to bring my work home and just use the computer. Sigh....
Macbook is running 10.7.2
Time Capsule is a new 2T unit
Printer is Canon iP4300

The thing that really bothers me is that when I connect the printer direct to the TC, the Mac sees it, but not the Time Capsule... ***?!?
Resetting the print system may...or may not....help here.

You are power cycling the entire network after you make a change in the USB connections, correct?
A powered USB hub will run $15-20 or so. Highly recommended.

USB hub and internet sharing stop working after sleep

Hi,
I have a relatively new Bluestork USB hub I purchased to connect multiple USB devices I have at the same time. It used to work correctly under Leopard, but now it stops working each time the computer wakes up from sleep. I have to restart the computer for it to start working again. Both link and power LEDs stay on, even when the hub is not recognized.
My second problem is related to internet sharing. It stops working after each sleep/wakeup cycle and the only way to make it work again is to restart the computer. It used to work correctly before Snow Leopard as well.
I have all the Mac updates installed.

Thanks Barry.
The hub is on its way to the manufacturer for after sales service...
But the issue with AirPort remains the same, even after resetting SMC.
Some clarification:
* It happens just after computer wakes up from sleep. Restarting solves the problem and the issue doesn't arise until computer goes standby again.
* The whole WiFi card becomes unresponsive. It is not only the Turn Off button, but the whole functionality is stopped. The card can not be activated/deactivated and it doesn't connect to any network. If it is used for internet sharing, clients are unable to connect.

Macbook Air + 30" Apple Cinema Display + Powered USB hub

I just received my dual link DVI to mini display port adapter in the mail today, and so far it's working just fine connecting my newer generation Macbook Air to the older 30" Apple Cinema display (the Air is closed, with an Apple wireless mouse/keyboard connected via Bluetooth).
I'm wondering if anyone has any success connecting a powered USB hub to either the adapter itself or the 30" display in order to gain some USB functionality out of the Air? I have a powered 4 port D-Link hub which worked fine directly into the Air, but I can't seem to power any devices when it's hooked up to the 30" display or directly into the adapter. I can't even get devices (external powered hard drives, Mbox) to work when plugged into the screen directly (no hub).
I called AppleCare about the problem and they said they don't support USB hubs via the 30" Apple Cinema Display when connected to the Macbook Air, but if anyone has any experience with this situation or if someone could offer me advice to get USB functionality out of my MBA + 30" ACD, it would be greatly appreciated!

Unfortunately not.

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.

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.

Can I use a USB hub to connect to multiple USB ports from one GPIB-USB-HS?

I have one instrument which has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple PCs to connect using USB hub at their respective USB ports? If so, how many PCs can I connect using the USB cable?
I have downloaded the latest NI-VISA from the website.
Solved!
Go to Solution.

You would first need a hub that allows you to switch between multiple pc's and then only one pc at a time would be connected and in control.
When you buy this special type of hub, one of the specs is how many pc connections it has.

Can I use a USB hub to connect more than 1 hard drive/flash drive device to the EA4500?

That's not possible, it was designed to handle one device at a time.

Setting up a USB external Drive with USB Hub on Airport Extreme

I have successfully hooked up the Airport Extreme Base Station (n) with two printers using a USB Hub. I am now trying to hook up an external hard drive(acomdata 250 gb). When I plug the hard drive into the Hub and turn the drive on the Airport Extreme Base station resets to amber and flashes green for a second then resets to amber again and it keeps doing that until I shut the drive down. I have a Mac Book Pro and an iMac on the network as well as a HP pavilion a730n on the network. I am able to share files between the PC and the Macs; however I can't seem to share the external hard drive. I tested the external hard drive by hooking it up directly to the Mac book and after a few seconds it mounted correctly and I was able to read and write.
Any help with this would be greatly appreciated.
Thank you.
Nick

What version of the AE firmware are you running? If you upgraded to 7.1, LOTS of people have discovered that Apple broke the USB connectivity for both disks and printers big time. With the 7.1 firmware version a few people can see the disks, but most people CANNOT see the printers.

Multiple Printers on USB Hub with Airport Express

I have been testing all day and I think my question is already answered. However, I would like to confirm with the gurus in here: Can AE be hooked up to a powered 4 port USB hub to which three printers are connected?
In the hardwired situation, there seems to be no problem. All three individual printers are recognized by Printer Setup Utility on the computer to which the USB hub is attached. When I attach the USB hub to the AE and restart the hub, only the first (closest to the USB out cable) is recognized, no matter which one I place in that first socket. And only that first one is seen over the wireless network.
I was looking for a way to allow other computers in the house to be able to utilize these three different speciality printers (labelmaker, DVD printer and LaserWriter), without having to have the connected computer always on as host.
Any suggestions would be appreciated-short of buying two more Airport Express units.

Can AE be hooked up to a powered 4 port USB hub to which three printers are connected?
Sorry, but no. The USB port on the AirPort Express Base Station (AX) can only accept a single USB printer. (ref: http://docs.info.apple.com/article.html?artnum=107857)
