hi there, when i connect my mobile phone to a recent HEAD (amd64; r211393) i get the following: ugen3.3: <Samsung> at usbus3 umass0: <USB Mass Storage Interface> on usbus3 (probe0:umass-sim0:0:0:0): TEST UNIT READY. CDB: 0 0 0 0 0 0 (probe0:umass-sim0:0:0:0): CAM status: SCSI Status Error (probe0:umass-sim0:0:0:0): SCSI status: Check Condition (probe0:umass-sim0:0:0:0): SCSI sense: UNIT ATTENTION asc:28,0 (Not ready to ready change, medium may have changed) da0 at umass-sim0 bus 0 scbus9 target 0 lun 0 da0: <Samsung SGH-i550 1.0> Removable Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: 3777MB (7736320 512 byte sectors: 255H 63S/T 481C) when i try to read stuff from the phone, it resets and i get this: ugen3.3: <Samsung> at usbus3 (disconnected) umass0: at uhub8, port 3, addr 3 (disconnected) (da0:umass-sim0:0:0:0): AutoSense failed (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0xa, scsi status == 0x0 (da0:umass-sim0:0:0:0): lost device (da0:umass-sim0:0:0:0): removing device entry it both happens if i mount it and read files or if i directly read something from the /dev/da0 device using `dd`. interestingly it always crashes after the same ammount of data read: dd: /dev/da0: Input/output error 4+0 records in 4+0 records out 4194304 bytes transferred in 3.333149 secs (1258361 bytes/sec) after a few retries the usb port i was using becomes unusable and nothing is being detected any longer. i'm pretty sure this didn't happen a few weeks ago, but now it does. cheers. alex -- a13x
