Re: Problems with USB hub in Studio Display

Ok, so I read a couple of posts here about USB hub problems with studio displays. Well... lucky me. I just got a used 17" studio LCD from craigslist.com (a local person) only to discover a day after getting it that it abruptly tries to go to sleep on its own; or the usb hubs in the back stopped responding; and/or it would intermittently flicker on and off like it was trying to go to sleep but couldn't. The screen itself is perfectly fine and clear when its own and I can get it to stay on for awhile with no problems, but just from my impression from the thing, this problem is going to continue. Was there ever a reasonable solution for this USB issue? My computer was running fine before on a 17" CRT Studio Display. And unfortunately, I've already given that one away.
<--- Poor student, so I'm hoping I'm not SOL.

Is your USB hub a self-powered one? Meaning, does it have its own external power supply?
If it is, make sure its power supply is plugged in to a live source. Also, some self-powered hubs have a small selector switch, allowing the choice of bus or self power; if it has such a switch, be sure it is not set to "bus".

  • Problem with usb hub 3.0 to connect printer and hd

    Hello,
    I have problems with using a usb 3.0 hub to connect a HD and a printer to my Time Capsule. HD is found and works properly. Printer is visible in programms but doesnot work.
    How to fix this.
    Ciao Pieter

    OK, plug the hub back in with the printer.. delete the current setup on the computer and try reinstalling it.
    But it tells you something if the printer is not recognised..
    Why don't you just share it from the computer.. USB printer are not supposed to be plugged into a network device. They are designed as local printers.

  • MSI A55M-E33 problems with USB Hub

    When I boot with my USB Hub plugged in the screen will stay black and I get a 9C, 99, 92 or A2 error. Often after a few seconds this will disappear but sometimes it will just hang on 9C forever. Without the USB Hub plugged in it will boot straight into windows with no errors, but the internal buzzer will give one long beep and two short beeps.
    I used MSI live update 6 to upgrade my BIOS from W10 to W50. Inside the BIOS screen it is given as E7721AMS v32.5.
    The boot mode is Legacy + UEFI, and the boot order is:
    Boot 1: SSD (win 8.1 64 bit on here)
    2: DVD
    3: UEFI Hard Disk
    4: UEFI USB CD
    5: UEFI USB key
    etc
    My 2nd hard drive isn't listed as an option, though in another section of the BIOS (can't recall which) it is listed as being in a SATA port.
    USB devices are a wifi dongle, wireless keyboard & mouse receiver, and a D-Link DUB-H7 7 port usb hub (with 2 external hard drives attached).
    Any ideas what I can do? Would a different usb hub solve the problem?

    So I phoned a local computer repair shop, and he said it sounded like a faulty USB hub. He advised me to buy a PCI-E usb card and plug the devices directly into that. I was confident he wasn't trying to just sell me anything, as he didn't have these cards in stock and suggested buying one online.
    So I bought one of those cards and plugged the external HDD's directly into that. It has solved the problem with hanging on 9C (the beeping problem seems to have just disappeared by itself). Now I just momentarily get a 99 and A2 error then it boots directly into windows 8. Unfortunately the external drives won't appear for about 30 seconds, and also I can't use my wireless keyboard or mouse for the same amount of time.
    I'm fairly sure its not the fault of the drives. Today I've plugged them into two windows 7 laptops and booted those and the drives show up immediately. Same with the USB hub.
    Does it sound like a faulty motherboard? Or something not set correctly in the BIOS?

  • Problem with USB hub on network

    I recently added a USB hub to my mac mini server, which has the harddrives plugged in. Its a powered hub and within the confines of the mini is perfect.
    However on the network I can see my mini, home folder and public folder, but cannot see the harddrives connected to the hub.
    Is this a 'feature?'

    HI,
    I knew you were going to ask that...
    The only Information on the Hub is Logitech Premium 4 Port USB Hub  (2.0)
    And of course I no longer have the packaging...
    Picked it up last year at a Local Electronics Store for about $30...

  • MSI K8N Diamond - Boot problems with USB devices attached.

    Hi There.
    I have been seeking the forums, but havent found the answer to my problem yet. 
    This is how it goes with ANY USB devices attached to either of the four USB ports on the Motherboard.
    When i turn on my system, it hangs in the POST right after displaying the BIOS version (Which I have updated to 1.6) - I cant use my Keyboard to get to the BIOS setup.
    Without USB devices attached...
    The system boots without problems. And in Windows XP SP2 i can insert my keyboard, mouse etc. and everything works great - both USB 1.1 & 2.0 devices.
    I have disabled the KB/USB.. in BIOS and I have disabled the "Boot on other device" option as well.
    As I have found on this forum, a lot of people have problems with USB Front panel and D-Bracket (USB ports) connectors causing the system to hang - But my D-Bracket (USB connectors) and my front USB port is at this time DISCONNECTED - so this cannot be the problem.
    The D-Bracket shows the "Bios Sign On" information - and stops at that point 
    Am I having a malfunctioning Motherboard here, or are there any solutions to this problem?
    Please help me as I am desperate to have my system work properly.
    Regards
    Stieper

    Well I have read about that somewhere in here, but my problem is NOT with an USB hub, but with any USB device attached to the motherboard's USB slots. It is driving me nuts to be honest!! I think it might be time for RMA 
    What do you say guys - is my Motherboard ready for RMA, or do I have to try something specific berfore sending it to the retailer??

  • Airport Extreme - problem with usb printer and usb disk

    I have Airport extreme with firmware 7.1. I try connect usb disk and usb printer with usb-hub to airport. I can't get disk or printer working. Also try connect only disk or printer without usb-hub to airport getting same problem. How I get disk and printer working with wireless network (windows pc computers)?
    1)
    My printer is HP PSC 1210 all-in-one ( http://h10025.www1.hp.com/ewfrf/wc/product?product=90764&lc=fi&cc=fi&dlc=fi&lang =fi&cc=fi&y=0&x=0 )
    - printer seems working fine after installing bonjour printer installing wizard.
    - I get error (in windows) when I try print document from word. Error only says "error printing" in status value.
    - In airport utility all seems ok. Airport see usb printer "Hewlett-Packard psc 1200 series"
    - printer protocol is RAW and driver manufacture HP (also try with microsoft driver)
    2)
    USB disk is Targa Databox II 250
    - Airport utility says "Disk needs repair. Errors were found with a disk connected to your airport base station. please connect the usb disk to your mac or pc and use disk utility or another disk application to repair the disk"
    - I have connected Targa usb disk to windows pc and run scandisk and defreg. No errors found in windows. Result..no help for airport

    I have a similar problem to your second issue. Tried connecting a Netdisk to the USB port of the Airport Extreme and it also said there was a problem with the disk. Have performed a low level format on the disk and Airport Extreme still complained the disk had a problem.
    After unplugging the disk, my route decided to stop allowing wireless connections even after rebooting. Ended up having to hard reset the Airport Extreme and reconfigure it with my old settings to work again.
    FWIW, the first Airport Extreme I purchased today only worked on 802.11a and steadfastly refused to work on b/g so had to get a replacement. I suspect Apple's quality control is not quite as good as it used to be.

  • K7N2 deltas mainboards have a problem with usb devices ??

    Ok here is my problem..
    I had installed WinXP Pro with SP1..
    I got a 20 GB USB2.0 disk.i connected it on the both front or rear usb ports.
    When i tried to transfer files to my usb disk or to my PC, in the middle of the copying, i got "Write Delay Failed" error and lost my usb connection..

    Now, i have an DSL modem..Last night, i was disconnected from internet and my modem's lights gone..I plug it again, no lights..restarted my PC, also completely shutdown Windows XP..Again no lights..
    Then, formatted PC and installed windows 2000 Pr and SP4, until now, my modem worked fine..But USB 2.0 ports are still no use for my usb disk...
    In bios , it's enabled as USB 1.1+2.0..
    I think this K7N2 deltas have a problem with usb 2.0 devices and Win XP Pro..
    Some guys talking about, removing 9th wire earth, but couldn't understand which wire from where ? From mainboard or from usd device's cable ?
    Those cables are fabricated, i think it's impossible ?
    My processor is Athlon 2500+, ram Twinmos 512 DDR 400
    Thanks for reply

    I'm also having this problem. It's happening with my USB flash disk. I was almost buying another one when I tried it with Windows Vista on the same machine and it worked ok, then I tried Arch Linux (with kernel 2.6.30.5) on another machine and got the same error. After that I tried Ubuntu and it worked ok. Seems that Arch's kernel doesn't like my USB flash disk.

  • Satellite M70-190 - problem with USB

    Hi!
    After uninstall Windows XP and BIOS update, i have a problem with USB ports. My USB flash drive does't work. Windows find it as USB flash drive, but i can't find it in "My computer"
    So have anyone idea about this problem?
    PS External HDD works perfect, as USB mouse, and USB WiMax modem.
    Im hoping someone out there can help with this problem.

    Is described issue the same on all USB ports?
    I mean, I have Satellite M70-159 in front of me and since long time I use 8GB SanDisc and 2GB Toshiba USB stick and both devices are recognized properly.
    I still use original Toshiba WXP installation (updated of course).

    Okay... I've just found the solution. It's really simple, just plug the phone to the MacBook, fire up iTunes, check the "Sync Photos from iPhoto" option, make sure all the other options are not checked, and just sync. Voila! my iPhoto library is now in the palm of my hand.

  • Satellite M30X: Problems with USB 2.0 external HDD

    Hi,
    I have a Toshiba Satellite M30X. I recently bought myself a 200GB External Hard Disc. It has its own Power supply. If I connect it with USB 2.0 to my Laptop it happens to diconnect and reconnect permanantly. Sometimes it works, then I can put Data on the Disc. Then again it diconnects and reconnects many times. I've already tried another USB Port, but there is no difference. It's very strange, because I connected the External Hard Disc to many other Computers (Laptop and Tower) and it ALWAYS works!!! Its only with my Laptop it disconnects and reconnects the whole time. As I said, not always. Sometimes it works for like an half an hour or so then the action starts again ...
    Can somebody help???
    Greez Lutz

    Hi Andrea
    I really dont know why this happen. A friend of mine has the same problem with his desktop. While copy process runs the HDD is suddenly disconnected and there is also acoustic sound when the hardware is removed.
    I have connected his HDD on my Tecra and there is no problem. I really dont know what the problem can be. Maybe there is some problem with OS because I can not believe that there is some contact problem with USB ports.
    If you use many different USB devices at the same time maybe there is some conflict between few different drivers. Sorry but it is not easy to give some precise explanation.
