i've got the same problem but with /dev/hda. it was working fine before except for this one time when it didn't. i had compiled a kernel. i just restarted and it worked. so i doubt it's a kernel issue. it's happening again now again, with another kernel. i doubt it's even a driver/module issue, but just to let ull know, the fs modules were included (vfat). why does this happen anyway? (works most of the time)

I have a similar problem with a SanDisk Cruzer Mini 128 running on SuSE 8.2 with a 2.4.20 kernel.

On my desktop machine, I can get the thing to mount, but on the laptop machine I have, it hangs trying to mount. When I do a dmesg, I see that the thing is being assigned to /dev/sda1,... but it won't mount no matter what I do.

Frustrating. I can only assume it's a chipset related bug thing with USB services...

After upgrading to 2.6.3 the problem continued however I made the following changes :

1) removed the scsi emulation from the kernel
2) re-boot with the usb_storage device off
3) ran modprobe usb_storage
4) ran modprobe usb
5) lsmod

6) turn on usb_storage device
7) ran cdrecord -scanbus ( only way I know to see scsi devices address)
1,0,0 100) 'IC35L090' 'AVV207-0 ' 'V23O' Disk

At this point I still could not mount /dev/sda1 /mnt/usbhd ? HOWEVER !

I tried this next :

8) fdisk /dev/sda1

There was a message about block 0 that would be corrected with a "write" before
leaving fdisk. ( sorry for not coping the message) Well this always freaks me out so I just quit fdisk instead. When I quit fdisk the light flashed on my usb_storage disk so I tried mount /dev/sda1 /mnt/usbhd again. AND IT WORKED !!

I can only guess something weird was written to block zero at some point and prevented me from mounting the disk. I won't know if it was a complete success until I try to re-boot with the mount /dev/sda1 parameters in fstab

Any how for now my system is running 100% on kernel 2.6.3 Just need to figure out how to load the modules on boot instead of running modprobe manually. I think there is a module.conf file that takes cae of this.
