I have 5 Qualcomm 888 HDK boards, which I'm using to drive tests using adb connection over USB to my desktop that is downloading and running tests on them. 3 of the dev boards are rock solid and have been up and running for weeks. 2 of them keep dropping the USB connection after a few hours. The devices are not rebooting, if I unplug the usb-c connection on the dev board and replug it reconnects to my desktop no problem. I have a screen attached, and it shows nothing visible that I can see that might help explain this, I've looked at the logcat output, and nothing obvious there either.
So how would an android developer go about debugging this flakey USB problem?
