Hmmh, what version of FreeBSD and what SCSI controller are you using?<br>
|
|
I find it strange that a user-level SCSI program would hang the entire<br>
|
|
system. I suppose it might be possible for the scanner to block the<br>
|
|
SCSI bus if something bad happens, but it should not lock up the<br>
|
|
entire system. Hence I wonder whether the problem might be with the<br>
|
|
generic SCSI driver, rather than the UMAX backend.<br>
