I'm all for it.
The bluetooth kit probably goes there too.
Also, the usb_raw header should be made public too (and cleaned up,
I've a pending commit on that but as you are touching it...). The
driver cookie struct should be moved out of it, and the names should be
B_ised.
There is a libusb port working (almost) now, I had it half done and
someone finished it, using this header.
I'll also change SANE to use this API as it's more on line with other
existing APIs (and some projects (ffmpeg...) dislike using C++).
Currently SANE uses the devices published by usb_scanner driver, which
is both useless (does nothing fancy) and uses a redundant list os IDs,
meaning one must both update sane and the usb_scanner driver.
