when i do 'sg-scan -i' i have :
sg_scan -i
/dev/sg0: scsi0 channel=0 id=0 lun=0 [em] type=5
PLEXTOR CD-R PX-W2410A 1.04 [wide=0 sync=0 cmdq=0 sftre=0
pq=0x0]
/dev/sg1: scsi1 channel=0 id=0 lun=0 [em] type=0
Generic Traveling Disk 1.11 [wide=0 sync=0 cmdq=0 sftre=0
pq=0x0]
where /dev/sg0 is my burner and /dev/sg1 is my USB disk ...
the result of 'sg_map' command is :
/dev/sg0 /dev/scd0
/dev/sg1
so it seems that sg1 device is not linked to a scsi emulation... what
can i do ? any idea ?
i'm running a sid with kernel 2.4.20
...
CONFIG_SCSI=y
CONFIG_BLK_DEV_SR=y
CONFIG_SR_EXTRA_DEVS=2
CONFIG_CHR_DEV_SG=y

(SCSI emulation burner is working great)
thks !
