I'm about to start a project for the Compute Module where I use a barcode scanner but I don't know if it's better to use the PS/2 or the USB version.

If I could choose, I would go with PS/2. I what to keep the PIs USB port alone to simplify the access to the flash memory.

I think I'll need a logic level converter. But what protocol should I use? Are drivers already available? Will this be transparent for the applications running on the Pi?

The Raspberry Pi does not support PS/2, so the USB version is probably better.
