    USB Unknown device


    Hi
    I have an Acer desktop running win 7. I keep getting two unknown usb devices but there are no usb device connected. I have tried disabling the devices, unstalling drivers and even formatted the HD, but they keep popping back. I have updated all my drivers.

    In device manager the have this as "strong name for drivernode" (translated from norwegian) usb.inf:Generic.Section.NTx86:BADDEVICE.Dev:6.1.7601.17586:usb\unknown

    They are really driving me mad! How can I get rid of them?

    Can you post a screen shot of your Device Manager with the 2 problem devices expanded?

    Also, can you look on the Details Tab for those devices, and under the Property drop down, see what it lists for "Hardware IDs"?

    If truly you have nothing at all plugged-in to your PC's USB ports, does your PC have a built-in card reader? Any other built-in that is USB related? If yes, then I would look for updated drivers for whatever reader/gizmo you may have.

    If not, well, please explain what you mean by unknown devices "popping up"--I don't know what you are seeing specifically. Screenshot(s)?

    Apart from what these "pop-ups" are that are annoying you, I might've said to simply ignore the entries in DM if the PC is otherwise working properly.

    P.S. It occurs to me that "of course" you have USB devices. Unless yours is an ancient PC you have a USB mouse or USB keyboard. Maybe a USB webcam? If mouse or keyboard, does it have any special features e.g. multimedia buttons? Acer PCs will typically have some sort of ancillary software associated with these features e.g. Dritek Launch Manager or some such...

    I dont have a card reader so it cant be that. I am usually an apple guy but need this pc for som programmingwork. Keyboard and mouse are usb and plugged in, but tyhe have been changed and unplugged and it hasnt helped either. Did that before i formatted the disc.

    Thanks for all help and here are some screenshots

    Sorry to press, but you're still not being clear--what is "popping back"? Where is the 2nd "unknown device"? Why are they "driving you mad"? How is this unknown device keeping you from getting your work done?

    Usually unknown devices sit in Device Manager and don't bother anything. I can't tell from your description how this is impacting the operation of your PC.

    They keep going on and of, making the connection sound and so on, showing the alert messages. The second device didnt show up today. As I said I am used to macs and sure know my way around them but havent realy used windows for the last 10 years. I think this messages is a fault and dont like it. I appreciate your effort, but if you dont think its a problem then good for you - its still a problem for me. As I said in my first post I even did format the HD to get rid of it. If its common in the windows world to have unknown devices in the device manager then I'll just have to keep up with it for some weeks - and then its Linux time
