yeah, this "mistake catching" aspect is the only thing stopping me doing
autodetection.

Since

#define PIPE_ISOCHRONOUS                0

in usb.h, these two macros do the same thing!  I think I am going to go
for a simple "use_iso" flag.

More about this in another email.

> PS : any news about the quirk patch ?

I think I will incorporate the "options" version.

Ciao,
