I was attempting to get my BBB to recognize my USRobotics USB modem. It showed 
up when I entered lsusb, and went through the set serial commands for it to 
recognize it, but it would not show up as a tty device, after having it 
connected for about 2 hours, I did another reboot, and the board no longer 
responded. Only the power light would light up, but none of the others. After 
doing a bit of research, I believe I ended up overdriving the current through 
the USB port. The BBB specs say 100mA is provided, but the modem apparently 
uses between 230-350mA. I guess I should have used a powered USB hub.  Now I 
guess I'm kind of out of luck. I'm just a bit confused why enough power was 
supplied by the BBB to power on the modem rather than it being under powered 
and staying off (like when I try to hook it up to my RPi boards).
