Well, you can also just test out the "maybe it's the extra zero byte
for hidusb" directly, without capturing any packet trace.

In scubapro_g2_transfer(), see how it does that:

        // BLE GATT protocol?
        if (io->packet_size < 64) {
                // No report type byte
                status = io->packet_write(io, buf+1, csize+1, &transferred);
        } else {
                status = io->packet_write(io, buf, sizeof(buf), &transferred);
        }

and the difference is exactly that the BLE GATT stuff does _not_ want
that silly report type byte.

libusb doesn't really either - it was added just for hidapi.

So try just changing that

        if (io->packet_size < 64) {

to a

        if (1) {

and see if your Debian case magically works.

(Of course, this is in _addition_ to all the USB ID hackery to make it
use the right device ID)
