I have vfat in the kernel and have reformatted my usb stick in windows (formatiting in linux won't work). All modules needed for a usb stick are built in the kernel. Any ideas on how to fix this? I am using udev and 2.6.9 custom kernel. Below is some output:
Thanks
[root@wookie jjohnson]# mount /dev/stick
mount: /dev/stick: can't read superblock
dmesg when plugged in and after mount command is run:

Maybe, yah. You need to change your fstab. You've got the right approach, but its a little off. Put the following in your fstab.
/mnt/usb /dev/stick vfat noauto,user 0 0
Then you should mount with the following
mount /mnt/usb
Look at the man pages for mount and you'll see that you just had the syntax switched around a bit.

Actaully your way is backwards... All my other devices are set up the way I had it.... Anyway I just tried it for sake of showing it doesn't work that way (modified fstab to your way too):
[root@wookie jjohnson]# mount /mnt/usb/
mount: /mnt/usb is not a block device
dmesg didn't put anything new in it either.

I was able to test a Lexmar stick and it worked fine... My guess is something changed in the latest kernel and my Sandisk is giving it a hard time. After I try to mount it the device LED shuts down also, and it disappears from the /dev/ listing. No idea why this is,and why it works just fine in Windoze. Oh well, I'll go get a Lexmar stick

Strange. I've got a 2.6.9 kernel (stick also OK with 2.6.9-nitro), a "no name" usb stick and SDDR-09 compiled into the kernel. My dmesg gives:
usb 1-2: new full speed USB device using address 2

then a "mount /dev/sda1 /mnt/tmp" give me access to by stick (ext2, used for backups). I don't bother with an entry in fstab as I only use it once each week.
cat /proc/bus/usb/devices gives

You say you can't format it in Linux. To me "format" means creating a blank file system. Can you partition it in Linux (fdisk)?
Offline
By format I mean mkfs.vfat /dev/uba -or- mkfs.vfat /dev/uba1.
Fdisk returns (dev/uba) superblock error or not a (dev/uba1) block device response and gives dmesg a bunch of these and then the LED on the stick goes out:
end_request: I/O error, dev uba, sector 120
Buffer I/O error on device uba, logical block 15
end_request: I/O error, dev uba, sector 0
Buffer I/O error on device uba, logical block 0
fdisk and mkfs.* for my CF media just fine.
I don't know what it is about the Sandisk usb stick
I searched google and found a minority of people with similar problems but no solutions.
I also tried with and without Sanidisk support built in with the kernel. And the problem is reproducable on my laptop as well.

Having low level USB block device compiled in cripples some usb stick support... Go figure, problem solved.
