It doesn't look like the drivers will work with this. I found this thread:
http://www.mythtv.org/pipermail/mythtv-users/2003-April/002508.htmlIt doesn't seem to be supported by either the ivtv drivers (which work with the pvr250/350), or with the blackbird drivers we're working on.
I found this project to write Linux drivers for it:
http://pvrusb.sourceforge.net/But it doesn't seem to be active. Here's another project:
http://pvrusb2.dax.nu/but it also isn't finished.
So from what I can tell, there are no complete Linux drivers for this product.
