A couple of questions:
1) Where do I get the angstrom image that Adafruit uses? I am going to try start fresh and see if that is the problem with the USB Hub in the BB.
2) Are there messages in dmesg that would indicate that the USB Hub is malfunctioning?
3) Are there any diags that I can run for the USB Hub?
BTW, my suspicion is that the wifi nub that Adafruit sells fried the BB USB Hub. Anybody else had this problem?
