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

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 canīt 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?

Dominik

Update : I attached the Debug Logs for further analysis.

Hi James,

this will not work. I donīt 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,

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

Default No driver found after update

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.

Partially,
Installed the latest DisplayLink driver, at first sight with no success, but then did the following:
1. go into device manager, selected the faulty device and choose update driver software.
2. search driver software on local pc
3. use select from driver list installed on ...
4. remove the check mark from show compatible hardware
5. find the usb display driver list
6. select from displaylink drivers the one, that matches the hex-code hardware id
7. installed that driver
After that, atleast the video worked as usual, audio didn't. But probably you'll have more luck. For me this issue is of no more interest, because I set up a completely new machine, which has a 4 channel graphic card. One channel over hdmi. Thus I don't need the extra external usb->hdmi device any more.
