[CLUE-Tech] problem with usb 6-in-1 card reader

[Eric Jorgensen]

Hello,

I have a Dell Latitude C810 running RH9 and am trying
to read a Lexar memory stick using a USB device.  The
device is an Iogear GFR206.  I couldn't find a link to
it on iogear.com, but here are some specs:


http://prodspec.ibuyernet.com/proddescrspec_id_470943_Iogear_GFR206.htm


The device works properly under win2k (and under win2k
under vmware on this linux setup) and shows up as
device "F:".  However, I cannot access the device in
linux.

After:
# modprobe usb-storage
# modprobe sd_mod

Here is the output from /var/adm/messages

Now the only thing I can figure out, is that the lexar
memory stick has two banks of 128M, selectable by a
tiny switch on the side of the stick, and this is
affecting how linux sees the size.

I've googled on this, but haven't really found
anything apropriate to this problem.  Does anyone have
any suggestions on where to keep looking?

Thanks,

Eric
