Model 100 unresponsive after factory reset

First, let me say I’m not a programmer and have no experience as such. I’ve been using the Model 100 since kickstarter, however, and this is the first time I’m having difficulty.

When I came back to my PC this morning, my keyboard was lit as normal, but unresponsive. After unplgging and then reseating all cables, it went dark. I then opened Chrysalis, unplugged the USB cable, held down the PROG key, and reconnected the cable. As usual, the PROG key lit red. I then attempted to update and restore to factory defaults. The left hand column flashed green for about 4 seconds and then a single key (usually PGDN) lit solid green. After clicking the OK button to reconnect, the connect to serial port dialogue pops up, but it states “no compatible devices found”.

Does anyone have any suggestions or tips?
