Hello, I have been doing some testing in an attempt to support two USB video capture devices on the same bus. For a single device running with maxpacket of 3072 per microframe, the EHCI driver is indicating 57% utilization of the bus (the sysfs stats already takes into account the fact that only 80% of the bus is available for isoc traffic). Is this expected behavior? By my math, an alternate of 3072 should take exactly 50% of the available bandwidth. Have I misinterpreted the spec? I'm willing to spend some cycles to dig into echi_sched.c if somebody can offer some insight as to whether this is expected behavior. I just want to avoid taking the time to debug this, only to find out that it is behaving according to spec. Thanks in advance, Devin -- Devin J.
