USB Scanner attached Windows 2008 Terminalserver works for one user, not for another
Posted on 2014-12-29
I have a Windows 2008 Terminalserver. Attached to that is a USB document scanner. Drivers are available and installed, the device is visible in device manager. There is one program installed on the server that is supposed to use the scanner's TWAIN interface to scan documents.
Now, here's the funny part: Most users on that terminal server can start the program and it recognizes the WIA source and can scan just fine. Only for one user that program does not see any available scanner sources. So I figure it must be some issue in that user's profile, but haven't found anything about scanners in the HKCU-section.
Note: I have written the program that should scan myself. It's a relatively simple VB application and does nothing overly exciting when listing all available scanner sources. If it works for one user, it should work for all others, too...
Do you have any idea what could make Windows 2008 behave in such a weird way?
Thank you and best regards,
