I'm using FreeBSD 6.0-rc1, and I'm having trouble with removable usb memory drives. I plug the device in, and get this from dmesg: umass0: LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2 There is no mention at all of /dev/da0, which is, as I understand it, the device that is traditionally presented to mount. usbdevs sees the device, and gives this output. port 8 addr 2: high speed, power 70 mA, config 1, JUMPDRIVE2(0xa300), LEXAR MEDIA(0x05dc), rev 1.25 This occurs both with GENERIC kernels, and a custom kernel that I configured. The custom configuration is listed here: http://www.dickinson.edu/~zeiglerr/STRMKERNEL Other things of interest. At random intervals, unplugging the device and replugging it gives me this out of dmesg: umass0: LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2 da0 at umass-sim0 bus 0 target 0 lun 0 da0: <Generic STORAGE DEVICE 1.25> Removable Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: 250MB (512000 512 byte sectors: 64H 32S/T 250C) (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x10, scsi status == 0x0 However, the mount command hangs in this case (I left it, and came back an hour later and it hadn't mounted). The USB drive works, as it is autodetected and mounted by Mac's and various other USB memory drives are not properly recognized either. On a whim, I booted into a FreeSBIE live CD that I have, and it was automounted and functioned correctly. One last little bit of interest, booting hangs immediately before attempting to mount / if I boot with the device plugged in. Booting continues normally when I unplug the device. I am not sure if this is significant. I would appreciate any help that could be offered. Thanks. -- Ryan Zeigler Dickinson '08
