So I tried plugging in my USB keyboard when the update froze at “Waiting for device, exit with ctrl-c” but nothing happened. In fact, I do not even get to the point where one needs to hit fn-esc or LAlt-RAlt-Start. All I can do is reboot to get the keyboard back.
How recommendable is it to switch to QMK?
is it somehow “stable”?
can I safely switch back to stock firmware?
Is the USB Device Bug the only known one?
you will have gamepad + select+ball as scroll
(on lates stock you have fn + ball as scroll)
yes

Yup, I fixed this. They work great now.

May someone else has trouble to flash the version because of Failed to open serial device -w option of dfu-util and a power hungry USB-Device like a USB ventilator helped in my case - just plug it in and out during the wait - somehow the USB-Host reset helped doing the rest:
sudo dfu-util -d 1EAF:0003 -a 2 -w -D clockworkpi_uconsole_default.20250725.bin -R

What about the problem with the keyboard and trackball disconnecting if you connect anything to the USB port? Has this been resolved?
that’s not the QMK issue itself (probably it could reconnect usb device though), but hardware’s uconsole’s. Seems like less problem on CM4 than on CM5.
and seems like there is a solution, feel free to try on your own risk: Fixing uConsole power delivery limitations with CM5 - #16 by QuantumKraken

Even plugging in some power-hungry device into USB does not move things forward for me. I am at the point of just giving up. Things still work, after all.
can you update the stock firmware to the latest version by instruction from their github?

At this point, I do not know which firmware I have installed any more. I just re-installed the stock firmware according to the uconsole wiki page on github:
~/uconsole_keyboard_flash $ sudo ./flash.sh

Then used maple_upload, but both operations yielded errors:

Is there a simple way of seeing the currently running firmware version?
@yasbean Did you tried my version of the command with the -w to flash?
Yes, I have. That is where I get stuck.

Thank you for asking!
So I was able to reproduce your situation and successfully reverted back to stock from QMK.
To do it I connected by ssh from laptop and run command twice. As I understand after first try it go to bootloader state and flashing works on the second run. (Probably you can replace ssh with external keyboard):
first time:
$ sudo ./flash.sh
Failed to open serial device.

It helped without restart. Bye-bye QMK.
@olly Is there any git repository for the firmware or only your private binaries?

The repo is here. Make sure you’re looking at the uconsole branch.
