Maybe someone can enlighten me on this... I have a 250GB maxtor drive that I am trying to use as an external drive. I bought a usb2 enclosure for it and had trouble with it on my gentoo box. I later found out it was because it was a Genesys chipset which is broken on 2.6.x from what I understand.
After some reading of the compatibility list on linux-usb.com, I decided to just buy another enclosure with the Cypress Semiconductor usb2 bridge. After installing, it is dyeing with an error message (dmesg output follows): usb 3-6: new high speed USB device using address 2 Initializing USB Mass Storage driver... drivers/usb/core/usb.c: registered new driver usb-storage USB Mass Storage support registered. scsi4 : SCSI emulation for USB Mass Storage devices Vendor: Maxtor`6 Model: Y2u0P0` ` ` ` ` Rev: 0 0 Type: Direct-Access ANSI SCSI revision: 02 SCSI device sdb: 1563976576 512-byte hdwr sectors (800756 MB) sdb: assuming drive cache: write through sdb:SCSI error : <4 0 0 0> return code = 0x8000002 Current sdb: sense = 70 b ASC= 8 ASCQ= 3 Raw sense data:0x70 0x00 0x0b 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x08 0x03 0x00 0x00 0x00 0x00 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 SCSI error : <4 0 0 0> return code = 0x8000002 Current sdb: sense = 70 b ASC= 8 ASCQ= 3 Raw sense data:0x70 0x00 0x0b 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x08 0x03 0x00 0x00 0x00 0x00 end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 unable to read partition table Attached scsi disk sdb at scsi4, channel 0, id 0, lun 0 USB Mass Storage device found at 2 usb 3-6: USB disconnect, address 2 Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0 It says it is attaching, but with those errors I am unable to fdisk /dev/sdb. I added the generic scsi module as a test because I read somewhere you might need it, so you can probably ignore the sg stuff.

I am running a stage1 gentoo build, currently running gentoo-dev-sources-2.6.5-rc1. I have tried 2.6.4, 2.6.5, and 2.6.6 with no luck. I run a serial ATA boot drive, WD raptor 76GB, and have scsi disk support compiled directly in the kernel because of that. Thanks for the help.
