Confused Cant mount R60 linux using USB. Help RAM GUY!

I can't mount my r60 in linux via USB. It's formatted ext4 with a couple partitions. The wierd thing is I can plug it in via SATA and mount it just fine. Also I can install lilo to the mbr and boot it via SATA or USB! In FAT format it is mountable in OSX over USB. But when I plug it via USB linux doesn't give it a sd[a-z] assignment but rather sg0, which is "not a block device" according to mount. Heres the dmesg:

[ 816.578030] ehci_hcd 0000:00:0f.5: port 4 reset error -110
[ 816.578053] hub 1-0:1.0: hub_port_status failed (err = -32)
[ 816.846733] usb 1-4: new high speed USB device using ehci_hcd and address 11
[ 816.997730] usb 1-4: configuration #1 chosen from 1 choice
[ 817.009651] scsi4 : SCSI emulation for USB Mass Storage devices
[ 817.050326] usb-storage: device found at 11
[ 817.050326] usb-storage: waiting for device to settle before scanning
[ 822.048191] scsi 4:0:0:0: Direct-Access Corsair CSSD-R60GB2 PQ: 1 ANSI: 0
[ 822.048706] scsi 4:0:0:0: Attached scsi generic sg0 type 0
[ 822.049623] usb-storage: device scan complete


and lsusb:

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 013: ID 1b1c:1ab8
Bus 001 Device 002: ID 1286:2001 Marvell Semiconductor, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The r60 is the one with no description. Am I going crazy or whats going on here?!?!

I am sorry Nick but I would suggest you contact the maker of the version of Linux you are using.

I am having the exact same problem. The disk can't be mounted with usb on linux. The problem is that Linux is not creating the /dev/sd* device needed.

I have tested with 3 different usb disks which are working fine, so it's not a general software problem. And I have tried to mount the disk on 3 different computers without success so its not a problem with the computer. (And the disk is working fine when using usb with Windows, except that it is called a fixed disk which it clearly is not).

A much better description of the problem including debug output can be seen at http://superuser.com/questions/22531...eate-sg-device
But it seems there is a bug in the firmware on the disk where it set scsi_level=0 which seems to cause problems.

Did you ever get it to work?

ps: I have tested the disk with Fedora 13, Fedora 14 and the newest Ubuntu. And they all have exactly the same problem.

If it will run properly when connected to the S-ATA Port I am sorry but there is little we can do.
