Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), 
Intel(0x0000), rev 1.00
 port 1 powered
 port 2 powered
Controller /dev/usb1:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), 
Intel(0x0000), rev 1.00
 port 1 powered
 port 2 addr 2: full speed, self powered, config 1, Motorola Phone 
(V3)(0x4902), Motorola Inc.(0x22b8), rev 0.01
Controller /dev/usb2:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), 
Intel(0x0000), rev 1.00
 port 1 addr 2: full speed, power 90 mA, config 1, product 
0x2441(0x2441), Actiontec Electronics(0x1668), rev 5.46
 port 2 powered

output did not hang. Is there anyway to change it so its not self powered?
