Mounting usb pendrive

[Mark Ferry]

Have you compiled in PC BIOS (DOS) partition table support?

CONFIG_MSDOS_PARTITION=y

menuconfig: File Systems | Partition Types | PC BIOS (MS DOS partition 
tables) support.

I assume your ipod may well have been fat formatted.

Also note that it's using the UB driver introduced in 2.6.9(?) rather 
than the older scsi usb_storage driver.

Many of the features in the old driver may not yet have been implemented 
in the UB driver (CONFIG_SCSI_MULTI_LUN equivalent ?!).

The solution is to remove the UB driver from the kernel...
  (CONFIG_BLK_DEV_UB)
