Tytera Be gentle! TYT MD-UV390 connection problem

[VK5AC]

Hi there, TYT MD-UV390 HH. Can program in the unit, now connecting to PC for programming. Windows 11 desktop. (Core security has been disabled by registry).
Have the ST DFUse drivers 3.06 loaded, the original supplied TYT cable and I can see the "USB Digital Radio" in the control manager under Universal Serial bus device section, when the cable and the radio are all connected and radio is turned on. This looks like normal USB driver availability. "Digital Radio in USB mode".

Then I start the "CPS MD-UV390 V2.39" software which loads just fine. Then I press the "read from radio" and OK, then an error message shows straight away!
This error is "Please check that USB is not occupied or not connected".
Seems like the program is not connecting to the USB port to me.

As an alternative there is a alternative program called "DMR_Codeplug_Editor.exe by G6AMU version 1.1.21.0" which is supposed to work with several DMR radios.
When I load that program, select a new codeplug for the TYT MD-UV390 the radio connect button becomes active. Press this loads a communication module screen.
On that screen there is a lot of options like load codeplug, send codeplug, load firmware, send firmware.
Select Radio is blank but when click in here a UsB device shows up. Seems to me that this is the id of the radio hanging onto the usb cable. However any attempt to read or write comes up with an error message!
I have tried all TYT downloads and their driver for DMR radios.

open failed
-----------------------------------------------------------------
So any clues? I am about run out of ideas. Having worked with the small handhelds and the USB to serial cables and the driver problems and fake chips in there problems this one had really got me. Very frustrating.
Open to suggestions guys.

It would be interesting plugging the radio and cable into a Linux computer and then run sudo dmesg. Lots of info would pop up for sure.

I wonder if there might be something similar in Windows CMD or Powershell. Might be worth a search or perhaps a Windows guru will chime in.

The factory CCR CPS is garbage. The same team writes it for all the CCR companies. I suggest you read the link, & consider using the openGD77 CPS, & FW. It really improves the radio in every way. It turns Clark Kent into Superman.

Intertesting. Here is the fix.
-----------------------------------------------------
The problem is that STM have 2 completely different DFU drivers for their MCU's
All OS's before Windows 11 seem to load the older / correct drivers, for Windows 11 it installs the new / incompatibe driver
These are the drivers which are compatible.
downloads/drivers/Dfuse_3.0.6_drivers.zip
You can also get the drivers by finding a firmware update package from TYT or Retevis for the radio, however its not easy to find these firmware update packages on either TYT or Retevises websites
----------------------------------------------------------------------------------------------------------
Then the driver appeared in the Universal serial bus controllers section as "STM Device in DFU Mode". And not in the "Universal Serial bus devices" section. Now we have read and write capabilities to the Radio.

Just a lot more to learn about in actual programming.
