Win7/64 - The drivers for this device are not installed. (Code 28)

Hi,

got the same problem after update via Microsoft-Update-Service. Driver for the device not found (Code 28). Tried to uninstall the new driver and reinstalled the original (version 5.5 something), which previously worked, but with no success. Added the output of the debug-tool.
Just to check that the device isn't broken, i installed the original driver on a fresh Windows7x64 (VM): that worked. But i would like to have the device back working on the real PC. The newest driver 7.6M0 doesn't fix the issue either.
