The umax backend uses fork() to create a reader process in its code.
At least with USB scanners, that makes it impossible to access the
scanner. Maybe it's the same with SCSI scanners?

There is now code for using threads on MacOS X instead (sanei_thread).
But the umax backend has not yet been converted to use that code.

But I'm not sure if that's really the reason for your problem.
