problem with Olympus USB camera on 8.0 RELEASE

The camera in question is an Olympus C-2040Z, I've had no problems using 
it with 6.4. I tried rev. 7 some time ago but plugging the camera in 
always caused a panic and crash so I stayed with 6.4. Now that 8.0 is 
out I'd like to move on and the good news is that with 8.0 I can 
connect the camera without a panic but the bad news is that although 
the system detects the camera I'm not able to access it. On plugging in 
the camera I see the following console messages:

ugen0.2: <OLYMPUS> at usbus0
umass0: <OLYMPUS C-2040ZOOM, class 0/0, rev 1.10/1.00, addr 2> on usbus0
umass0:  SCSI over (unknown 0x00); quirks = 0x0100
umass0: could not setup required transfers, USB_ERR_INVAL
device_attach: umass0 attach returned 6

... and camcontrol devlist returns nothing at all

I only see this problem with this particular camera, 2 other USB devices 
(Nikon Coolpix 3100 and Canon iP4500 printer) can be accessed OK.

In case the info is any use for comparison here's the messages when I 
connect the camera on the same PC running 6.4:

 umass0: OLYMPUS C-2040ZOOM, rev 1.10/1.00, addr 2
 da0 at umass-sim0 bus 0 target 0 lun 0
 da0: <OLYMPUS C-2040ZOOM 1.00> Removable Direct Access SCSI-2 device
 da0: 1.000MB/s transfers
 da0: 62MB (128000 512 byte sectors: 64H 32S/T 62C)
