I just started using two AB9-Pros and both of them have a bit of a strange issue. Whenever a USB memory card reader (one being the one built into my Dell 2405 and the other being a SanDisk card reader) is plugged into one of the four on board USB ports, the system will have issues booting. Sometimes I am able to reboot without the hang, other times not so much. This happens at stock settings but when I was over clocking, I had to unplug the thing all together as I'd never post (even with LONG waits) and I'd be reset to my previous settings.
On one of the machines, I could never reboot. Every time it would try, it would hang at the post screen. Powering off and back on would fix that. I eventually moved the card reader to the USB hub on the monitor (Dell 2001FP) and I am fine there.
On the other machine, I couldn't boot until I unplugged the USB cord. I haven't tried it on the USB expansion cord (dongle, thingy).
Any ideas? Anyone else have this issue? What about other P965 boards?
(I wonder if it has something to do with the BIOS being able to boot off USB drives and trying to scan for some drives that aren't really there.)
