You have the Manufacturer and the Card type, but no Card model..
The card model starts with VP-XXXXXX

A few possibilities that could exist ..

(1) The card model is not supported by the driver..
(2) You are doing something wrong..
(3) Some bugs in the driver..

Option (3) is less likely as i haven't seen the error what you have, 
with any others. Or is anybody having the very same error.. ?
