Our SCSI controller is supported by the Fsys.aha8scsi driver
which is started from basic OS image (.boot file).
Now I would like to get an access to the external USB cdrom.
The io-usb manager starts fine and usb command shows my
device without any problem.
When I start Fsys.umass driver then the following error message is printed:
 SIM="" HBA=“QNX USB Storage”
[00,0,0] type=05 ver=00
Can’t attach to Fsys (resource busy)
and in result cdrom doesn’t appear in /dev directory.
How can I solve this problem ?
Is there any limitation in the QNX4 Filesystem manager (Fsys) ?
It seems that I can’t run two SCSI drivers in the same time.
