I think "usb start" and "usb reset" are identical, but anyway:

=> usb start
(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 dev 0

USB device 0:
    Device 0: Vendor:  Rev:  Prod:
            Type: Hard Disk
            Capacity: not available
... is now current device

=> ext2ls usb 0:1
** Bad partition - usb 0:1 **
