I'm not convinced this is the right solution to this problem.

IMO, this problem is caused by the MUSB driver being broken for
suspend/resume.  I've reported this problem (and an RFC/PATCH)
already[1], but I don't think the driver has been fixed.

Can you try my patch[1] to see if it fixes your problem as well?
