what kind of error do you get when you try to mount?
I found this in the kernel documentation:
===================================================
THE /proc/bus/usb/devices FILE:
-------------------------------
In /proc/bus/usb/devices, each device's output has multiple
lines of ASCII output.
I made it ASCII instead of binary on purpose, so that someone
can obtain some useful data from it without the use of an
auxiliary program. However, with an auxiliary program, the numbers
in the first 4 columns of each "T:" line (topology info:
Lev, Prnt, Port, Cnt) can be used to build a USB topology diagram.
Each line is tagged with a one-character ID for that line:
T = Topology (etc.)
B = Bandwidth (applies only to USB host controllers, which are
virtualized as root hubs)
D = Device descriptor info.
P = Product ID info. (from Device descriptor, but they won't fit
together on one line)
S = String descriptors.
C = Configuration descriptor info. (* = active configuration)
I = Interface descriptor info.
E = Endpoint descriptor info.
=======================================================================
give a look at the /proc/bus/usb/devices file.
Maybe (!) there is something that could help you to find what's wrong, for example the right device to mount (if /dev/sd* was wrong).
