I am able to reproduce the disconnect+reconnect behavior even without hald running. So I guess that this clears hal of suspicions. Sorry for the noise. Hans, I've put a usbdump file here: http://people.freebsd.org/~avg/kindle.usb.dump.gz This is is without hald running. The following system log messages correspond to the dump: Apr 2 10:49:41 trant kernel: ugen2.2: <Amazon> at usbus2 Apr 2 10:49:41 trant kernel: umass0: <Mass Storage> on usbus2 Apr 2 10:49:41 trant kernel: ugen2.2: <Amazon> at usbus2 (disconnected) Apr 2 10:49:41 trant kernel: umass0: at uhub2, port 5, addr 2 (disconnected) Apr 2 10:49:43 trant kernel: ugen2.2: <Amazon> at usbus2 Apr 2 10:49:43 trant kernel: umass0: <Mass Storage> on usbus2 Apr 2 10:49:44 trant kernel: da0 at umass-sim0 bus 0 scbus8 target 0 lun 0 Apr 2 10:49:44 trant kernel: da0: <Kindle Internal Storage 0100> Removable Direct Access SCSI-2 device Apr 2 10:49:44 trant kernel: da0: 40.000MB/s transfers Apr 2 10:49:44 trant kernel: da0: 3090MB (6328768 512 byte sectors: 255H 63S/T 393C) -- Andriy Gapon
