I'm baffled as to why bfgminer keeps crashing on this system. Why is it looking for USB devices when I'm trying to mine scrypt?

I used WeBisect session "purelithiumNov29" to try and bisect the problem. This is what it gave me once I bisected all I could:
There are only 'skip'ped commits left to test.
The first bad commit could be any of:

We cannot bisect more!
The build I got before that message didn't have the error I described in my quoted message, but It did have another issue of crashing almost immediately on connecting to a pool. Not sure how I could bisect that one... As of right now 3.2.1 is the only functional build for my machine.
