I'm hoping one of you guys have experience with this issue, as apple couldn't help me as its a weird little problem. So when starting up my macbook pro, I hold option like normal to see the available start up volumes. This works fine, I see my OSX Lion, Bootcamp, and recovery partitions. When I select the recovery volume the computer boots it just fine, but if I select the OSX or bootcamp partitions the computer freezes and i have to manually restart. Then, i tried the same thing but I removed my usb devices and both volumes work perfectly! Does anyone know why I can't use start up manager to boot when I have usb devices plugged in? It was working before and the computer boots just fine when going to the selected start up disk and usb devices are connected.
The devices I ahve connect are:
KBTalking Race 75% keyboard
Logitech 935 Wireless headset dongle (I know , the sound sucks but I like being wired free while gaming).
Anyway, thanks for looking/helping with this thread.
