Using simultaneously SCSI HDD and external USB CD under QNX4

Hello,

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:

Fsys.umass -vvvvv &

[00] 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.

Regards,
Jacek

Take a look at the “fsys -N name” option (set unique version name).

ie Fsys.umass fsys -Numass

The -N option did a job.

Thank you,
