Hi!
Im trying to attach a usb2 200gb drive to my laptop that is runnig
2.6.10-rc2-mm3. Upon connect I get this in dmesg:
usb 1-2: new high speed USB device using ehci_hcd and address 4
scsi0 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 4
usb-storage: waiting for device to settle before scanning
Vendor: Maxtor 6 Model: Y200P0 Rev: YAR4
Type: Direct-Access ANSI SCSI revision: 04
SCSI device sda: 398297088 512-byte hdwr sectors (203928 MB)
sda: assuming drive cache: write through
sda: sda1
Attached scsi disk sda at scsi0, channel 0, id 0, lun 0
Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0
Then I try to access the disk (via fdisk or mount anything) and I get
the following in dmesg:
usb 1-2: reset high speed USB device using ehci_hcd and address 4
usb 1-2: scsi_eh_0 timed out on ep0in
usb 1-2: device descriptor read/64, error -110
usb 1-2: scsi_eh_0 timed out on ep0in
usb 1-2: device descriptor read/64, error -110
usb 1-2: reset high speed USB device using ehci_hcd and address 4
usb 1-2: scsi_eh_0 timed out on ep0in
usb 1-2: device descriptor read/64, error -110
Then it stalls a while and this shows up:
scsi: Device offlined - not ready after error recovery: host 0
channel 0 id 0 lun 0
usb 1-2: USB disconnect, address 4
scsi0 (0:0): rejecting I/O to offline device
scsi0 (0:0): rejecting I/O to offline device
usb-storage: device scan complete
usb 1-2: new high speed USB device using ehci_hcd and address 5
usb 1-2: khubd timed out on ep0in
usb 1-2: device descriptor read/64, error -110
And repeats this.. I think you get the point ;)
The process trying to access the disk hangs.
Note: the drive works flawless under windows and has worked fine under
linux during various stages of the 2.5 and early 2.6 kernels :)
