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.

Check Include subfolders

Thanks,
James

Hi James,

this will not work. I don´t have a ethernet device available.
The only device i can see (with a yellow warning sign) is PR08 DisplayPort Dock.

See my screenshot ...

Hi,

Sorry - I must have ethernet on the brain!

Does trying the above steps on the PR08 DisplayPort Dock in device manager get you anywhere?

I'll get this escalated internally.

Thanks,
James

Hi !

Have tried that several time - no luck.

What can I do now?

Hi,

I've raised this internally for investigation.

However in case there is an issue with the installer files that are local to your system please try these steps:

1. Reboot your system

2.
Right click on PR08 in device manager
Select Driver
Select Update Driver
Select Search automatically for updated driver software

Thanks,
James
