"device unknown" on every USB port


Check that the ports work OK with another device - a printer for instance. They are pretty tolerant things when it comes to connectivity. If no joy there, go into "Device Manager" (I assume we are talking about Windows) and look in "Universal Serial Bus controllers" (at the bottom of the list) and see if there are any conflicts or absence of controllers. If so you could try to get Windows to fix itself by booting up with the Windows disk in a drive and following the onscreen instructions to repair the installation.
Do you use USB for your keyboard or mouse? Do they work? Or a joystick or game controller?
If none of the above help, your motherboard is probably kaput.
You could try a PCI (or PCIe) board with additional USB ports. Not the ones that plug into the internal USB headers (if the M/B is broken they probably won't work either).
That's all I can think of without seeing the PC myself.
After that - build yourself a new PC! Good luck.

USB port gives new message "unknown device"


hello allan213

my name is ausi.

is it on all usb ports only one of them if it is in only one of them then the message you getting generaly means one of thw follwng.

1- if it is in only one of the ports then try it with a different device as well to see if it is the actual port or not.

2- the device you have plugged in needs to have drivers installed. normally should have been supplied with it.

3- the device you plugging in is faulty and the system can not access it.

4- the system usb ports are overloaded. (too many usb devices connected simultaneously)

good luck

Please ensure that the drivers are compatible with windows 7 else try with compatibility. but it may work or not. If failed in compatibility mode, you would require the driver for windows 7 version

IN MY PI945GCM USB DRIVES ARE NOT ACCEPTING PEN


hi,
please check the device manager if USB is enabled there
to go to device manager
start menu > run > type in without quotes"devmgmt.msc" > the device manager look for usb (universal serial bus controllers)

if they are ok ( there shouldn't be any exlamation sign next to any usb device check expanding the title for universal searil bus controller)
neither they should be disabled no cross should be there next to them

then go to computer management by going to

start menu > rin > type in without quotes 'compmgmt.msc' >
removable storage > right click > properties > security > use, control, modify should be allowed for your user name

if this is also right click on disk management in same window and then insert the usb drive in check if it detects and show here, if it shows format the drive as fat

and now when you insert it the next time it will show automatically

if any of the above doesn't work

restart the system and then press F2 /delete key (whichever applicable in your case) to enter bios at mercury logo and check here if usb is enabled or not. if disabled enable it and follow the above steps again.

Further Queries are welcome

Usb problem


You shouldn't need the USB driver 2.0 from mercury because windows installs this with SP2. Suggest you un-install what you installed from mercury & update your version of windows (completley), through "Windows Update". Once windows is all updated & you have finished with a reboot. Plug your pen drive in a opened usb port. Open windows explorer. Scroll down & you should see an icon (left side of explorer), thats named like, Removable Disk. Give windows time to see the device. After a few minutes if your pen device does not show up try another usb port. One you know does work. If after a couple of minutes go by & you still don't see the device listed in explorer I would say the device is defective. Your Mp4 uses a cable to connect to the usb. Try connecting to another PC's usb port. It is possible the cable is dirty or bad.
