The kernel can see the "drive", but no partitions. And fdisk
doesn't believe it is there. To me, that suggests it has some other
form of partition. I suggest you select all the partition options
in the kernel (including 'Advanced'). If someone sent this to you,
ask them how they created it. If it is new, I guess whatever
options match current macs might suffice.
Alternatively, there are a number of different options under
CONFIG_USB_STORAGE for different hardware : again, try enabling them
You might also want to review the messages the kernel is giving
you, in case anything there identifies the hardware.
