I’m returning to BeagleBoard after a long absence, and have managed to get most stuff up and working, including upgrading to Debian (5-13-2016 release). However, I’ve got good video on my HDMI monitor so I can see a cursor, but I cannot get any mouse to work to move it. I’ve tried several and even went out and bought a wired mouse on the off chance that it would make a difference. I also tried hooking up a wired keyboard and tried a bunch of ctrl key combinations to see if there is any response. No luck. I can talk to the board over the USB ethernet via PuTTY, so I know the OS has not crashed.
How do I go about troubleshooting a problem like this?
