Hello all, Can't get my 2.5" USB drive to work reliably. The device has a ALI M5642 Chip and connects 2.5" PATA disks. Vendor 0x0402 is USB_VENDOR_ACERLABS /* Acer Labs */ which ALi is afaik. When I connect it: Dec 8 16:11:20 gw root: Unknown USB device: vendor 0x0402 product 0x5642 bus uhub3 Dec 8 16:11:20 gw kernel: ugen3.2: <vendor 0x0402> at usbus3 Dec 8 16:11:20 gw kernel: umass0: <vendor 0x0402 USB 2.0 Storage Device, class 0/0, rev 2.00/1.00, addr 2> on usbus3 Dec 8 16:11:20 gw kernel: umass0: SCSI over Bulk-Only; quirks = 0x0000 Dec 8 16:11:21 gw kernel: umass0:0:0:-1: Attached to scbus0 Dec 8 16:11:21 gw kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Dec 8 16:11:21 gw kernel: da0: <USB 2.0 Storage Device 0100> Fixed Direct Access SCSI-0 device Dec 8 16:11:21 gw kernel: da0: 40.000MB/s transfers Dec 8 16:11:21 gw kernel: da0: 38154MB (78140160 512 byte sectors: 255H 63S/T 4864C) When I try to dd/fdisk/bsdlabel the disk I tend to get Dec 9 12:47:49 gw kernel: (da0:umass-sim0:0:0:0): AutoSense Failed Sometimes the LED on the cage stays red until I reconnect it. When I first `usbconfig -u 3 -a 2 reset` and then reconnect the disk it is recognized again. Tried both on an Intel GM855 and a nVidia nForce4 system. Errors that pop up when transferring data: Dec 8 16:11:21 gw kernel: (da0:umass-sim0:0:0:0): SYNCHRONIZE CACHE(10). CDB: 35 0 0 0 0 0 0 0 0 0 Dec 8 16:11:21 gw kernel: (da0:umass-sim0:0:0:0): UNIT ATTENTION asc:28,0 Dec 8 16:11:21 gw kernel: (da0:umass-sim0:0:0:0): Not ready to ready change, medium may have changed Strangely it seems that this device was recognized on a previous version of FreeBSD see http://takaq1.plala.jp/freebsd/usb/index.html (not that I've tried!) Not quite clear what version of FreeBSD that is. Ultimately FreeBSD crashes when I play around too long.. Can anyone assist?
