The VP-3040 needs a bit more work. The driver was sent to the 
manufacturer for some lab tests. I will post the updates as soon as they 
get back .. Anyway 2005 should see some good drivers for Twinhan cards. :-)


The VP-3040 still needs some light working upon, upon receiving their 
reply i will fix up things..
