Hi folks,
The device in question is a voice recorder. It is supposed
to show up as a removable drive on the computer and be
accessible with a browser (such as IE) for drag and drop
upload and download via usb.
Further investigations have led me to conclude that this is
a two part problem. One part is a scsi/kernel problem, and
the second is a mounting problem I think.
To see if it was indeed a scsi problem and if the device could
be detected, I rebooted using a stock 2.6.8 kernel. The device
was discovered without a problem and the information revealed
is appended below. So perhaps there is a problem with my kernel.
Also I could not locate the files on the device so that
presents a second problem. No icon shows upon the desktop
for example.
As far as scsi modules go, dmesg shows nothing for scsi.
Likewise, lsmod reveals no scsi modules are loaded. However, in
/lib/modules/2.6.21.5/kernel/drivers/scsi/ I have ide-scsi.ko,
scsi_mod.ko, scsi_wait_scan.ko, sd_mod.ko, and sg_mod.ko. So
it could be I don't have sufficient scsi modules or perhaps
it's a boot problem in which scsi is not being started? On
the other hand, things worked with the 2.6.8 kernel using
the 2.6.8 modules of which there are a huge number.
So that's as far as I've gotten.
Here's the data from the 2.6.8 kernel I mentioned.
Hope it helps somewhat.
Many Thanks,
b.
