    USB ports

    One of our machines isn't displaying devices, such as memory sticks, which are plugged into the USB ports on the front of a computer for a particular user. This is an isolated problem with this machine and this user. Any ideas?

    Does it happen on another user?
    Is it a software issue, can you boot from a pendrive?

    Same as FN-GM,also is it just pen drives your using? aka if u plug a mouse in are you getting power etc for it, if its just pen drives check under disc manager check its getting a drive letter etc.

    It's user specific, nothing works in the front for the user. The pen drive flashes as though it's being recognised.

    We had a wierd problem like this awhile ago think it got fixed in a windows update tho, as the usb sticks would only appear if you put the stick in before the student logged on if the pc had a cd drive (random i know) Also another great one is windows sometimes will set the usb stick to the same letter as a network drive if your using network drive mapping.

    So if its one user it will probably be a profile issue. Have you wiped the profile and started a fresh?

    ive had success with weird problem like this with uninstalling some usb devices in device manger. I have also had succes removing keyboard and mouse access by selecting the wrong usb devices.

    worse case is you lose keyboard and mouse but they will be re-installed at next startup.

    If the memory stick is flashing, but not doing anything, go into Control Panel and run Add Hardware and see if it detects the hardware being there.

    You could try this - had a similar problem with a load of ACER GTs - not showing the devices, scanners, lego robots etc - this works [ and has worked with a load of other devices.... ]
    Anyway I knocked this up after some investigation.....

    You need to change the PASSWORD to your local PC PASSWORD & have the remove catroot2.cmd in a folder called c:\logs
    Oh yes and compile the AutoIT code to an exe....


    Code:
    rd c:\windows\system32\catroot2 /s /q
    Either do all that or work out what the script is doing and Henry is your Uncle's sister's cat's neice as they say....

    Code:
    ; AutoIt Version:  	3.2.8.1
    ; Language:        	English
    ; Platform:        	WinXP
    ; Author:          	Matt 
    ; Script Function: 	USB Admin Rights Box Fix
    ; Version:			1 Beta
    ; Date:				Sept 2008
    
    
    Opt("TrayIconHide", 1)
    SplashTextOn("USB Device Driver Repair by Matt","Remove any USB device from the computer NOW","300","50","-1","-1",2,"","","")
    Sleep(5000)
    SplashOff()
    RunAsSet("administrator", @ComputerName, "PASSWORD")
    Run(@ComSpec & ' /c net stop cryptsvc', '', @SW_HIDE)
    SplashTextOn("USB Device Driver Repair by Matt","Trying to fix problem - this may not work","300","50","-1","-1",2,"","","")
    Sleep(5000)
    SplashOff()
    Run("C:\logs\remove catroot2.cmd")
    sleep(3000)
    Run(@ComSpec & ' /c net start cryptsvc', '', @SW_HIDE)
    RunAsSet()
    If FileExists("C:\windows\system32\catroot2") Then
    	MsgBox(4096, "USB Device Driver Repair", "Ooops, Fix Failed, Re-boot PC and try again")
    Else
    	MsgBox(4096, "USB Device Driver Repair", "Lucky You - Fix may have worked, insert USB Device and cross fingers")
    	EndIf
    Exit

    Have you tried going into control panel/admin tools/computer managment/disc management and seeing if the USB stick shows up there? I had a problem in the past where the system was trying to allocate a drive letter that clashed with an existing network drive letter ... I changed the USB drive letter to a non used one and them problem was solved .....

    Cheers
