I seriously doubt it. :) I don't mind C coding a bit, but I'm afraid I don't know where to start here. Can anyone walk me through a low level troubleshooting process? Do I have to have CAMDEBUG in my kernel? (not a problem if I DO, but I don't right now) I'd personally like to know why the /dev/da0sN device isn't being created. I think identifying the reason for it not being created > Some of the cheaper enclosures use USB->ATA bridge > chips which aren't handled by the standard umass driver. Might be the case here. Windows XP detects it as a "USB to ATAPI" bridge though. The Coolmax Gemini enclosure (the one that works with FreeBSD) is detected by Windows XP as a genuine "USB to IDE" device. > Before anyone asks, these are evil, and don't talk SCSI/UFI/etc, they > talk ATA task file register over USB, so branching off ata is more > appropriate; I should be able to leverage most of the existing ATAng > code base for this. Well, I'd be happy to help you test if we can somehow confirm that my device is indeed one of these ugly USB->ATA devices. I'm not 100% convinced though. Take a look at these two posts that have exactly the same dmesg: http://lists.freebsd.org/pipermail/freebsd-current/2003-August/008504.html http://lists.freebsd.org/pipermail/freebsd-hardware/2003-July/000393.html The last fellow shows that his drive works perfectly under Linux with SCSI emulation. -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
