SEM-V completely steath after failed(?) firmware flash

[RogoRogo]

I recently flashed my VKB NXTs (one of them a merged device) to firmware v2.20.

In the process I also wanted to flash my SEM-V (standalone device) to the latest version.
I chose the correct firmware package, the flash seemed to work fine, the SEM-V restarted and then.... poof
"USB device cannot be indentified", device no longer there in VKBconfig, the whole show.

All lights on the SEM-V turn on correctly, but it seems to no longer have a hardware ID to be recognized by the OS on any level.

I tried the following.
- replugging on powered USB hub
- replugging directly on PC
- hardware reset on the device itself (button combination)
- change devioce # on the device itself (button combination)

but nothing works.
I have submitted a ticket but have not heard back for two weeks (oh look, a DCS pun ).

Does anyone have any idea what to do - I would really not want to consider this reliable and barely used module a write-off...

The SEM, like any other NXT module, can't work independently as a USB device - you'll either have to connect it to a Gladiator, like shown here, or upgrade it with a GNX HID Controller.

Thank you for the reply.
Well, of course my SEM V has a GNX HID, as you stated, otherwise it would have to be a merged device.
And as a standalone, it has been working flawlessly ever since I purchased it.

It was when I flashed the firmware to v2.20 (using the correct package), that the module - as described above - suddenly ghosted, despite a success message from the flash.

So again, my desperate plea for help remains.

What I have not done was take the GNX HID out, attempt to merge it with my LEFT Gladiatator NXT (that is already merged with a GNX THQ with WWII grip) - hopefully I will not have to try that, I will, but only if told to.

All I did was perform proper maintenance, and now my module is ghosting, as described - the hardware ID no longer transmits, not on OS level, not in the VKB suite, nothing.

Try the latest firmware and configurator from here.
The package contains a text file and an image, which you should review.

Thank you!

But - again - I must refer to my OP and my first reply -> how am I to flash anything if the SEM-V Module (with USB HID controller inside - and working flawlessly before the flash and still showing all lights when powered on) does..

• no longer transmit a USB hardware ID
• does thus not show up in zBootloader
• does not show up in VKBDevCfg
• does not show up in the device manager or any USB device checker

that is my problem, after doing a correct flash with the correct WHQL package from the manufacturer website (2.20C in that case) and a sucess message the device went inert when it comes to transmitting a hardware ID. And I have already tried all recommendations for replugging and hotstarting and even doing a button-press hardware reset.

So again, please help and advise (yes, I have made a ticket too which is as of now unanswered (for over a month as of today)

Disconnect the HID controller from the SEM and try flashing it. What firmware are you using? Show screenshots.
Show photos of the controller from both sides.
