Has this device always needed a reset? The interesting bits of the log are probably the ones immediatelly preceding the decision to reset it. Two possibilities come to mind: something broke the reset logic (the device is clearly not working right after the reset) ... or something changed to make the device go bonkers _before_ the reset, which seems a bit more likely with my current lack-of-facts. (Especially if rc2 works and mm3 doesn't.) - Dave > ... > > > 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..
