Hi
Me again, yes true, true I just don't understand the USB driver... The results
of checking out the partitions formatted on the pendrive
:/dev/scsi/host2/bus0/target0/lun0# ls
disc part1 part2 part3 part4
:/dev/scsi/host2/bus0/target0/lun0# fdisk -l
/dev/scsi/host2/bus0/target0/lun0
Interesting eh? I also checked /proc/scsi/scsi and it shows I have been
plugging in and out various pendrives of which
the USB driver keeps track...
:/dev/scsi/host2/bus0/target0/lun0# more /proc/scsi/scsi

Note there are 3 different types of USB pendrives ... the Ut165 just doesn't
work with the version of the USB driver...
The Ut165 pendrive mounts just fine on my Debian workstation which is running a
2.6.18 flavor of Debian... whereas
the TS7400 is still the stock debian that Technologics compiled and loaded into
the flash ( 2.4.26-ts11 :/dev/scsi/host2/bus0/target0/lun0# lsmod

Could there have been an update to the usb-storage driver ( that seems to be
the one that recognizes various partitions )
Also, should I load msdos filesystem driver or is vfat good enough??

It has 4 partitions, try
fdisk -l /dev/scsi/host2/bus0/target0/lun0
It will show you how the pen drive is partitioned. It might be that
the first partition is not formatted msdos/fat/vfat.
USB device assignement can be a bit of a pain. Just because you plug a
pendirve into the same usb socket doesn't mean it will always be allocated
the same scsi device! It depends on what else is plugged in and sometimes
on what has previously been plugged in. This is the same for all Linux
stuff, and is not particular to this device.

I'm pretty sure it's nothing to do with modules. You just don't understand
partitions and how USB works enough.
The reason this problem is dear to me, is that I have a web app, that allows an
operator
to plug their pendrive into the usb port to perform a backup of the
configuration data....
Well if they can't plug their pendrive , that's not a good thing, yeah...we
allow the
operator a second choice of using their filesystem...using tcp/ip...but what if
there is no network connection?? That is why I have to understand if there is
a limit of pendrive models supported by the usb-storage driver... if so, I guess
what version of this driver was utilized for this build?
THanks for your help!!
