Do you have any USB2.0 port to test?
When I implemented PID-filter for USB1.1 I reached also similar problem, 
but that was only for broadcasting MUX A in Finland. With other muxes I 
tested it was OK. I don't know why. Can you ensure that problems are 
only when viewing MUX A programs?
Anyhow, USB2.0 port and without PID-filtering your device should work 
like a charm.

When I get some time I will test and sniff how windows driver does 
PID-filtering.
