>Description:
	pilot-xfer (comms/pilot-link) does not backup Palm device.

	With kernel built for USB diagnostic, the following is logged
	when accessing Palm:

		ehci0: handing over full speed device on port 8 to uhci3
		uhub4: port 8, device disappeared after reset

	"pilot-xfer -b" finishes normally, except for incomplete result.
	Relevant kernel options:

		uvisor*	at uhub? port ?
		ucom*	at uvisor?
		options	UVISOR_DEBUG
		options USB_DEBUG
		options UCOM_DEBUG

	Kernel built with options:

		options 	DIAGNOSTIC
		options 	DEBUG

	after running pilot-xfer crashes:
