You don't mention your OS "patchlevel." Maybe some maintenance has fixed your problem?

Oops! This Does Not Work Here. :-/ Camera (Olympus) has SmartMedia card; usbd does properly sense camera attachment & make/model, but if I try to mount it, the OS reboots(!) I tried using fdisk to look at the camera's "filesystem" but got an "invalid sector size" & then "synchronize cache failed" in syslog. Here's the relevant syslog: Jul 4 13:48:01 <kern.crit> myname /kernel: da3: invalid sector size 3273166177 Jul 4 13:48:01 <kern.crit> myname /kernel: (da3:umass-sim0:0:0:0): Synchronize cache failed, status == 0x10, scsi status == 0x0 Restating, if I try to mount that da3 device (the USB camera with SmartMedia) I get what appears to be a lockup & the system reboots. :( Ideas?
