USB 2.0 Loopback plug - Benchmark mode - more detail about the History report?

[markalamo]

Hi,

I'm working with usb_example.cpp code under linux. Its not clear to me (from the code or PDF guide) exactly what measurement is provided by the History report entries.
Can I get more detail about the History report entries?

Do they provide bits per millisecond? Per frame or per microframe?
Are the History report entries measuring the hardware xfer speed from host controller to loopback plug?

Thanks,
Mark A

Each entry in the history buffer is the number of blocks transferred per frame or microframe (depending on the connection speed) between host controller and the loopback plug.
The block size is 64 bytes for full speed and 512 bytes for high speed.
Each frame is 1 millisecond and each micro frame is 125 microseconds.
