10.6.2 USB troubles

[waynem]

After a few issues, I was able to get my GA-EP45T-UD3LR running with full graphics (ATI 4850) and sound (ALC 888).

 

The only remaining problem appears to be USB related. First off, iTunes won't launch when I plug in my iPhone (I've tried both front and rear USB ports) but if I launch iTunes manually, I can sync and update ok.

The second, and I'm assuming related problem, occurs with any USB based network device. Tethering my iPhone or using a ZTE HPSA+ 3G usb modem/stick.

 

I've tried in both 32bit and 64bit modes.

Any ideas ?
