It would. Serial is ~11KiB/second. From memory, USB is ~0.5MiB/second (50 times quicker). It could be quicker, but we used the same (slow) serial protocol over USB. USB requires 32-bit Windows.

Ideally, use Ethernet. You'll get much quicker speeds (usually limited by the disk in the empeg). As usual the FAQ has you: https://riocar.org/FAQ/6/248.html#248

Maybe. The empegUpgrade process is a bit timing-sensitive, so might not work with USB/serial adapters. The last time I did an upgrade, I did it with the disks physically connected to a Linux desktop, but that's outside most people's comfort zone.

If you have one available, that'd potentially be best.

I'm sure someone else will be along shortly to give more advice. Here, let me see if saying his handle three times works: tfabris, tfabris, tfabris.
