Regarding the USB PID definition naming, there is no problem for me.
Actually, some product names were used in the modified versions of your
old driver, so I converted them to the format above just for
convenience. The only problem is that there are so many variations of
the Avermedia sticks that it's hard to give them proper names.

Some of this IDs are already tested (if we include the several
modifications of your old driver).

In particular:
AF9035_0CCD_00AA : confirmed working on Ubuntu.it forum with the old
driver (don't have the link);
AF9035_07CA_0825 : confirmed working on OpenPli forum with the old
driver (see link above);

Others comes from the official Windows drivers so they should be just
little variations of the retail products:
AF9035_07CA_A825, AF9035_07CA_0835, AF9035_07CA_3867.

This IDs are can be the more problematic:
AF9035_15A4_1000, AF9035_15A4_1002, AF9035_15A4_1003,
AF9035_07CA_A333, AF9035_07CA_0337, AF9035_07CA_F337
since there is little or no information about this products.

Anyway, this patch can be a reference for users willing to test the new
driver.
