Firmware Upgrade Hangs at %0

Ok, so performed the firmware upgrade last night and everything went along happily…except the upgrade stopped at 0%

An hour later it stayed at 0%.  Bit the bullet, tried the USB key with the **bleep**.  Panic Mode started to set in.  However, I did discover that if I plugged a SECOND USB key in with the firmware on it, the firmware upgrade suddenly started working.  Required both keys with firmware to be connected.  Strange but true!  Hopefully, if this happens to someone else, it might help them out too

I see that happen before, but usually it cause by the format on the flash drive. Usually coping the firmware update again or reformatting the drive seem to fix it.
