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

[moelski]

Hi !

I have win7 64 Bit and the Fujitsu PR08 (which is a DL3900 Chip) worked very well the last time. Today I got an driver update from Windows Update. I installed it and after that the device stopped working.
I tried to install the original 7.5M2 driver but can´t get my device back to a working state.
The Device Manager tells me "The drivers for this device are not installed. (Code 28)" for the PR08 DisplayPort Dock.

I tried to reinstall the driver and used the EndUserCleaner to clean up my system. Nothing helped right now.

Can anyone tell me what to do now?

Update : I attached the Debug Logs for further analysis.
