Attaching external mouse makes XO irresponsive

[joe]

Build Joyride 2026, firmware Q2D16, machines CSN74801BDF and CSN74804BE8.

Attaching an external USB mouse (either wired or wireless) makes XO absolutely frozen after ~ 5+ minutes. Power to the mouse goes off. The only way to shut the machine down is to hold a power button for at least 5 sec. Reproducible bug, checked several times with 2 XOs.

Does tapping the power button once help? Power to USB isn't supposed to be maintained during suspend.

If it doesn't, I'll need the output of "dmesg". If you don't want to hook up a serial console yourself, I can try it on one of my machines.

It doesn't.

Okay, back with me to investigate.

I'd be interested to know whether this happens on 703 too.

We made some serious changes to the touchpad driver and the way that HAL and evdev interpret the output of the driver in the 703->708 transition. It's entirely possible that we introduced a regression in USB mice.

It looks like a kernel issue, upon coming out of suspend. This is 2.6.22 on a Joyride build. Will retest with 703 and 708.

[dsaxena]

Just tried 703 and manually suspend/resuming the system via "echo mem > /sys/power/state" and was able to reproduce after a few iterations. The system does wake up and I still have serial console but the UI does not respond to keyb or mouse events at this point. If I suspend again, I now can't wake up b/c input events are not triggering the wakeup. I can still ping the machine but that does not trigger a wakeup either.

[dsaxena]

Just tried to reproduce with joyride 2079 and this is gone.
