That's all well and good, but on my end, it's (correctly) not detected as a wall charger (i.e., I get to 'Cancel' the connect to computer popup), and it really doesn't let me put it to sleep ;p.
Although, IIRC, that was after a reboot with the thing plugged in. I'll try a clean, unplugged, cold reboot, because I'm used to all kinds of weird and funky behaviour with the USB stack on iMX5 devices...

EDIT: Nope, no dice.
Not that's it's a terribly critical issue, but, still, it makes testing sleep screen related stuff slightly more annoying
