Hello all,
I have a 128MB Sony USB Memory stick (Micro Vault) but mounting doesn't work.
This is what I do:

modprobe usb-storage
(ok)
mount -t vfat /dev/sda1 /mnt/usb_stick

mount: wrong fs type, bad option, bad superblock on /dev/sda1,
or too many mounted file systems
(ups!)


This is what I get from lsusb:
Duplicate HUT Usage Spec at line 2650

Bus 001 Device 002: ID 054c:0105 Sony Corp.
Bus 001 Device 003: ID 054c:008b Sony Corp.

This is part of dmesg:

Can anybody help me please! (this thing was expensive)
Thanks a lot

I solved the problem myself:
It must be mounted like this:


mount /dev/sda /mnt/usb_stick
