This is what happens if I run usb reset twice:

=> usb reset
(Re)start USB...
USB:   Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... 2 USB Device(s) found
       scanning bus for storage devices... Device NOT ready
   Request Sense returned 00 00 00
0 Storage Device(s) found
=> usb reset
(Re)start USB...
