After doing a bit of searching - it seems this is a common problem -
The USB port just fell into the unit. This is definitely a design flaw since the USB port is used for the editor as well as something very important - RECORDING with the option of re-amping. I'm always careful when I walk around the USB cable (I try to remember to take my shoes off, but often that is not practical). FAS says I can send it back to them - it would only be $50 repair - but then of course there is shipping and insuring the unit. I'm wondering if a local computer repair shop that is decent would be a safe choice. Ian from FAS support (who has been very helpful) wrote me "It has 6 pins in total all need solder, 4 in a very small area that needs to be done delicately as to not damage the board which would prevent USB from working any more even with a new port."
I found this thread to be informative -

Any advice - ship it back to FAS or someone local?
