Hello, First excuse my english.
Since one week, on own/use a 0xcb static.
All composnent on the pcb where soldered by the vendor/creator of the kb except switchs that i soldered.
Since the begining, i have different problems.
Theses problems are on 4 different PC, laptop and desktop, Linux and windows
The keyboard didn’t like all usb cable/port. For exemple with ŕ custom cable, i use with all my others keyboards without pbms, on static, one time on 2 windows say "unknow device" when plugged.
On my desktop pc, impossible to flash firmware.
On some usb port, some letters write sometime several time (not always the same letters).
Finally, i found one cable and one usb port that work without problems since one week.
Yesterday, suddently after day and hours of using, when i press "u" it write yuhjbn.
Tested with via matrix keytester, same pbm.
Yesterday, i have unsoldered/resoldered the "u" switch, made several tests (wrote 200 tirme u without pbms) and think that it was the problem.
This morning after one hour of use, pbm came back again...
I have unsoldered/resoldered ŕ New switch and it worked 10 minutes.
After that i have tested another cable, to test, and with the new cable, U wrote U. I came back to old cable and U wrote U too, 10 seconds and pbm occur again. Came back to new cable -> same pbm.
Do you have an idea of what could be the pbm ? Contrôler, diode, pcb, other thing ?
Thanks for reading
