TBS 5927 driver not installed issue -error code 28

You can try self-signed debug driver and check debug messages with DbgView from driver

1.Unpack archive TBS5927-debug.rar
2. Enable test-mode and add my cert to trusted with testcert.cmd (Run as admin)
3. Run Dbgview and enable kernel logging (see picture)

4. Force update 5927 debug driver from device manager, check DbgView messages on driver init (see my sample log)

After running testcert.cmd as administrator I get this in command prompt:

C:\Windows\system32>C:\Users\SUPERB\Desktop\debug\testcert.cmd

C:\Windows\system32>certmgr.exe -add CrazyCat.cer -s -r localMachine root
'certmgr.exe' is not recognized as an internal or external command,
operable program or batch file.

C:\Windows\system32>certmgr.exe -add CrazyCat.cer -s -r localMachine trustedpublisher
'certmgr.exe' is not recognized as an internal or external command,
operable program or batch file.

C:\Windows\system32>bcdedit -set testsigning on
The operation completed successfully

Also, I didn't find the 5927 debug driver in device manager.

I added CrazyCat.cer manually in Trusted Root Certificate Authorities and Trusted Publishers.
I also did step 3 but the last step I couldn't understand it can you explain it more.

Windows still cant update the driver of the unknown device in device manager even when searching for drivers in the computer.
