Is 0208 in the interval of known devices > for which sddr09 works? The entry was added before 2.5.0 (more than 7 years ago), and I can't tell who added it. And the entry doesn't say anything about DPCM (multiple-LUN trickery). Ed, it looks like you're out of luck. Unless you can figure out the vendor-specific protocol used by that device, and modify the sddr09 driver to support it, you won't be able to use the device under Linux. Or am I completely off base? Did it used to work with an earlier kernel? If it did, can you get a usbmon trace of it?
