I plan to set up a Linux box for use with the QV3000 (among other things). So I'm just going to put together some links with the intent of creating a resource page.

UPDATE 9-May-2001
Harald Schreiber has gone and made a kernel patch for 2.4.2 to support USB access of Casio QV-Cams including the QV-3000EX. Others at the DP Review forum have reported sucess.

UPDATE 31-Dec-2000
The latest kernel 2.4.0 seems to provide support for USB. But my LLG (local Linux guru) thinks it's way too wobbly for someone like me to go near it.

The standard Linux interface for digital cameras is gPhoto. Multiple cameras supported but not for the new Casio cameras ... YET.

Robert Harrision has created:

a small tool for controlling the QV3000 record mode, including time lapse, from Linux (x86). It is being distributed as freeware. Linux users that are interested please look at http://3-cities.com/~rjh/
'edge' in this message had this to say about getting a card reader with the microdrive working over USB:
I just finished getting my Microdrive recognized as /dev/sda1. I'm using an old p166 with a Xircom PCI-USB adapter and a SanDisk SDDR-31 ImageMate II card reader. Kernel is 2.2.16-3mdk, which the usb-storage kernel module developer says shouldn't be used for usb mass storage devices. :) I don't know if it was needed, but I recompiled the kernel with usb and scsi support as modules. The backport patch for usb that I read so much about wouldn't work for some reason.

At first, I had troubles getting the drive to mount. It kept reporting "mount: /dev/sda1 is not a valid block device". The key was the sequence of loading the modules.
1. modprobe sd_mod
2. modprobe usb-storage
3. modprobe usb-ohci (motherboard usb may use uhci).
After that, I received a string of kernel messages about the drive and was able to do mount /dev/sda1 /mnt/temp. This allows me to copy files from the microdrive at hard drive speeds instead of the ten hour transfer via serial cable.
