[pvrusb2] KnoppMyth R5A26 backend with pvrusb2

[Mike Isely]

A long time ago the KnoppMyth community expressed an interest in including 
the pvrusb2 driver directly into KnoppMyth.  This was roughly back around 
last May.  At the time the driver was not all that stable so I kind of 
"warned them off" for the time being.  Since that time things have 
improved considerably.  A while I posted an update on the forum discussion 
thread, suggesting that it might be worth trying now.  I never saw a 
reply.  Probably the message wasn't noticed.  But since you have an 
interest in this, perhaps you might want to bend their ears a little - 
especially since you've already blazed the trail to show that it can be 
made to work.
