Hi !

I am currently running the public beta for my card which is 1.3.4+539 and
that is limiting the USB streams.

The last one with configurable USB streaming for my card was. 1.2.8+378


I hope the first one for your card 1.2.9+28 still has the option and maybe
1.3.0+59 do as well.

The changlog suggests to me that 1.3.1 is the first crippled one for your
card but since I don't have a 624, I can't check.

Best regards, Anders
