Search engines can catch my mail and help any future user of that camera. The camera is supposed to act as a mass storage device on a USB bus. It can be mounted on a file system, and images can be copyed, erased, etc... using usual file commands. There are some caveas to get the device to work though, because the camera does not seem to follow the USB mass storage specification: - The CSW signature is not 0x53425355 but 0x55425355 (go figure) - The camera does not support 6 bytes SCSI commands. DA_Q_NO_6_BYTE has to be set for the device in cam/scsi/scsi_da.c. Once that's done, i can mount the camera with 'mount_msdos /dev/da0s1 /mnt' and transfer pictures easily. The only problem i have is that, once removed, a probe of the devices will crash the kernel. For instance if i run /stand/sysinstall, the kernel crashes when the cammand probes the devices. I do not know why and did not spend any time looking for a fix. I hope that'll help anyone who wants to use the D-100 with FreeBSD. I have some diffs for the kernel driver source, but what i've done is really ugly because i am not very familiar with the drivers, but that could be used by someone who knows the drivers and is willing to modify them. -- lpj PS: I am not on the list. PS2: fyi the d-100 is a cheap ($250) digital camera, 1.3 MPixels. -- Laurent Joncheray E-mail: lpj@cisco.com Cisco Systems, Inc.
