Debugging USB stuff can be a bit ugly.
One technique is to have USB_DEBUG set in your kernel config file,
and then after rebooting, play with setting values of the
following sysctls: hw.usb.umass.debug and hw.usb.debug .
The other technique is to have two machines set up for
kernel debugging, set a breakpoint somewhere in the USB
code that would be accessed during an fdisk,
and single step through the debugger until you hit
the point where things reboot. It's not pretty....
