I have a Belkin 7-port USB hub. It has worked fine in 10.2, 10.2.1, 10.2.2, 10.2.3, 10.2.4 and 10.2.5.
Now, presumably because of some quick "fix" Apple made to 10.2.5 to stop the kernel panics with other USB hubs, random USB devices connected to my hub are not powering on after sleep. One day it might be my Bluetooth adapter, the next day it's my iMic, the day after it could be my Wacom tablet, and so on...
I can't believe how crap Apple's QA is nowadays.
Any hints on what I should to do to get USB back to the way it was in 10.2.5?
