The API hasn't been changed for years. The sanei functions may change,
but I don't think there has been a relevant change lately.

Just use the sanei_usb functions. They'll select automatically libusb
or the kernel scanner driver.

Direct hardware access like ioctl shouldn't be in the backends directly.

What about libieee1284? I have seen some defines for that? Does the
backend work with parport also? If yes, that'd need some work to only
use libieee1284 if it's available.

I'll check how much work it is.

cvs [login aborted]: end of file from server (consult above messages if any)

I'll try later.

Ok.
