You cannot receive all channels in the mux at the same time (at least in 
case there is more than 32 PIDs in the transport stream).

I think in theory yes. One program stream is typically less than 5 
Mbit/s and USB1.1 can carry around 12Mbit/s. Anyhow, you are now using 
USB2.0 with PID-filter which means USB can transfer 480 Mbit/s in 
theory. AF9015 does have 32 PID-filters which sets some limits. 32 is 
still more than enough for 2 channels....
