    Unhappy Disappearing Drivers!

    Several months ago I setup a Canon LiDE 110 scanner on my Toshiba Saterlite 660 i3 laptop, running Win 7 64bit. Windows update is active and the system appears to be working fine.
    I have not used the scanner for a while but as always when you need something urgently it always seems to go wrong!
    The problem in this case is the scanner works for one scan and then fails and reports a communication error with "code 5,155, 55". on opening Device Manager I find the device is missing replaced by an Unknown Device with error message: "Windows has stopped this device because it has reported problems. (Code 43)"
    I have repeatedly reinstalled the latest driver from Canon website and on every occassion the scanner works for one scan then fails reporting the same error and the device is once again missing from Device Manager.
    I have a similar problem with a bluetooth device but thats another story!
    Can anybody explain what is going on and suggest a solution?
    Best regards, Kevin

    That's a weird situation. Is the scanner recognized every time you connect it?
    Does the scanner complete a full scan and then fails?

    1. Ensure that the laptop is capable of supplying the current needed to actually run the scanner. Otherwise a powered hub may be needed.
    2. Reinstall the scanner fully.
    Unplug and remove the scanner from the computer. Remove the drivers related to the scanner in question;

    Wink Thanks you all. problem solved

    Thanks to Clint for that great link on hiden devices, but the simple solution came from Roadrunner! Once I changed the USB cable everything worked perfect; the device remained visible and the unknow device was no more. Thank you all once again.
    After following Clints advice I now have anouther question.
    Can I uninstall all unknown and uplicate devices in the hiden list of Device manager; I found tons of them; is it safe to delete them and let Windows rediscover any it may have been using?

    Hi Kevin,

    Glad you solved it.
    You can delete all the devices you want and Windows will rediscover whatever devices really exist on reboot.
