In my opinion, if it's involving looking at individual drivers, rather than
just at doing what's necessary to make the core work within Grub, then it's
being done in an unsafe way. I'll be glad to help have a crack at it if you can
tell me how to set up the right build environment.

I think I must've misunderstood you, then. Maybe you just said "serial" instead
of "serial number". If you mean what follows usb: in the device identifier,
then, yes, it's an optional serial number. I thought you were asking if brltty
treated the device as a virtual serial device.

Well ... I'd rather have a look at such code (there can't be much) to find if
there are other ways to implement it.
Basically, I hate hacking. I'd rather use projects like this one to find ways
to make the code more and more portable. It may be the tougher toad to travel,
but it's always invariably the one which yields the most fruit. This approach
has kept brltty's code rather clean in spite of the fact that it's grown to
support multiple platforms, multiple I/O methods, lots of new features, etc.
>We don't implement libusb
But there'll be some way to do USB operations. They just need to be impemented
in the correct set of low level functions. As long as autoconf can have a way
to know that the environment is Grub, then it can select the Grub set of low
level USB functions and the core will just work.
