Looking at the files that come on the CD I see that it's using the Mars
USB Camera Driver:

[Manufacturer]
%MarsMfg%=MARS

[DestinationDirs]
MARS.USBDCam.CopyDrivers=12

[MARS]
%USB\VID_093a&PID_010e.DeviceDesc%=MARS.USBDCam,USB\VID_093a&PID_020f

A bit more googling shows that linux has a Mars USB Camera Driver in the
kernel. And ghphoto http://www.gphoto.org/news/ shows support for MARS
USB drivers in libgphoto2 2.4.1., 2.3.0. etc. And I'm showing:
/usr/lib/libgphoto2/2.4.0/mars.so is available... unfortunately I don't
know what to do with it.

I also find the device listed here:
http://www.linux-usb.org/usb.ids
093a  Pixart Imaging, Inc.
	020f  Bullet Line Photo Viewer

So I'm getting closer...
