Hi Matthias,

I found that your last change (rev. 1.249) to src/sys/dev/scsipi/sd.c 
makes my digicam no longer:

 	noon% dmesg
 	...
 	umass0 at uhub0 port 1 configuration 1 interface 0
 	umass0: DSC DIGITAL CAMERA USB, rev 1.00/1.00, addr 2
 	umass0: using ATAPI over Bulk-Only
 	atapibus0 at umass0: 2 targets
 	sd0 at atapibus0 drive 0: <DIGITAL, CAMERA, 1.00> disk removable
 	sd0(umass0:0:0): readonly device
 	sd0: drive offline
 	noon% sudo disklabel sd0
===>	disklabel: /dev/rsd0d: Read-only file system
 	noon%

Backing out that change gives me a working cam again:

 	noon% dmesg
 	...
 	umass0 at uhub0 port 1 configuration 1 interface 0
 	umass0: DSC DIGITAL CAMERA USB, rev 1.00/1.00, addr 2

I haven't looked at your change in detail yet, but maybe you have an idea 
how to make both that cam and USB floppies work... (I can test changes for 
an USB floppy if that helps...)


Thanks,
