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 :) -- Regards, Christian
