Re: Cypress / First touch I/O module recognition by DS after suspend

This is really quite a serious problem, and FRC should make an update telling teams no to do this.

Thank you both for reporting similar issues.

We'd gone a similar route to Allison's team; we've configured our Classmate to not go to suspend when the lid is closed. But this has severe drawbacks in elimination rounds where you'd like to sleep it between matches to preserve battery (and speed the charging process when on charger between match).
