Recently acquired a GoPro "Digital Hero 3" digicam. It's got a USB interface and allegedly presents itself as a umass device. When I connect it, I get the following: Sep 1 09:25:57 working kernel: umass0: ZORAN COACH DSC, rev 1.10/0.00, addr 2 Sep 1 09:25:57 working kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Sep 1 09:25:57 working kernel: da0: <ZORAN COACH6 (I62) 1.10> Removable Direct Access SCSI-0 device Sep 1 09:25:57 working kernel: da0: 1.000MB/s transfers Sep 1 09:25:57 working kernel: da0: 982MB (2012160 512 byte sectors: 64H 32S/T 982C) Sep 1 09:25:57 working kernel: umass0: Phase Error, residue = 0 Sep 1 09:25:57 working kernel: (da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 Sep 1 09:26:07 working kernel: umass0: BBB reset failed, STALLED Sep 1 09:26:07 working kernel: umass0: BBB bulk-in clear stall failed, STALLED Sep 1 09:26:07 working kernel: umass0: BBB bulk-out clear stall failed, STALLED The device is inaccessible. I'm able to access it if I reboot to Linux, so the device isn't _completely_ broken. Some google searches turn up similar problems with other USB umass devices that seem to be universally solved by adding quirks to scsi_da.c. Is this the only way to fix this? I know terribly little about USB architecture, but it seems ugly to have to add a quirk for every single johnny-come-lately USB device that emulates umass poorly. I went looking to see if there were any sysctls to tweak, but have yet to find any. Should I file a PR to have a quirk added, or am I missing something? uname -a FreeBSD working.potentialtech.com 6.2-RELEASE-p5 FreeBSD 6.2-RELEASE-p5 #0: Sun May 27 00:53:14 EDT 2007 wmoran@working.potentialtech.com:/usr/obj/usr/src/sys/GENERIC i386 -- Bill Moran http://www.potentialtech.com
