Linus Torvalds 4dce920c79 Scubapro G2 usb: always use exactly 32-byte packets (plus report byte)
It turns out that the Scubapro G2 itself does not care at all, but
apparently some of the other dive computers that use the same protocol
do).

In particular, Vincent reports that his Scubapro Aladin Square downloads
ok with the USB ID's switched to c251:2006, but only if we send 32-byte
USB HID payload packets, even though the command itself is much smaller.
Otherwise it will simply not reply at all.

To actually download correctly, we'll still need to do some model-
specific USB ID updates, and there will be some model changes for the
Aladin Square, but this at least fixes the transport side.

Jef had actually already done this because of the Windows behavior side,
I just hadn't thought it could possibly matter. Mea Culpa.
