Montage 6 USB intermittently loosing connection to Computer

My Montage 6 had an electrical surge knock out the main board and the output board which luckily I was able to have replaced under warranty. Ever since getting it back from the shop it has intermittently been disconnecting from my computer and I don’t think they replaced the board the usb connection is on.

Does anyone know if this is the part I’m looking for to replace said board?
