My T5720 thin client has very dodgy USB legacy support so this project seems to be awesome for the need as I really do not want to use old peripherals. That being said, I have problems with mouse support I seem not to be able to figure out. I am using CH559 dev board which works but one LED is connected to P4.3 which conflicts with mouse data but aux output works. I also compiled custom firmware and mapped primary mouse to P2.2 and P2.3. Everything works when it works, however...
- T5720 usually does not recognize PS/2 mouse, no tricks seem to work
- "Something" happens and mouse is detected after which is always detected as long as I work with the machine
- "Something" happens again and mouse is no longer detected, usually after machine has been sitting unused
- Soft boot, cold boot, nothing seems to help but sometimes soft boot helps
For me this sounds hardware problem, dodgy wiring or something, but swapping kb and mouse does not help - kb works and mouse does not. Real PS/2 mouse always works. Sadly, I have no other computers with PS/2 ports...
Anybody have any ideas what could be going on...?
Ps. @serisman I think your schematics in GitHub has clk and data lines swapped for aux ports?
