I've been doing a bit of research into why my Casio QV-3500 camera won't
work under
NetBSD after I found out it did work with Linux. Here's what NetBSD reports:
umass0 at uhub0 port 1 configuration 1 interface 0
umass0: CASIO QV DigitalCamera, rev 1.00/90.09, addr 2
umass0: using ATAPI over CBI
atapibus0 at umass0 channel 0: 2 targets
probe(umass0:0:0): generic HBA error
A dig around in the Linux kernel source reveals:
/* Casio QV 2x00/3x00/4000/8000 digital still cameras are not conformant
* to the USB storage specification in two ways:
* - They tell us they are using transport protocol CBI. In reality they
* are using transport protocol CB.
* - They don't like the INQUIRY command. So we must handle this command
* of the SCSI layer ourselves.
*/
umass.c gives the impression that CB is not supported (but seeing I don't
know the difference, I could be misinterpreting...).
I can't see any obvious NetBSD quirks which correspond to these issues.
