I'm afraid I'm not familiar with this- why did .ep_fifosz_shift for
this case drop to 9? frx = 10 in the temp < 8 case in the removals of
the following hunks. Mostly curious because the others seemed to stay
the same.
Hi Andrew,
It might be an idea to keep the fifosz_shift at 10, else high-speed BULK
traffic won't be double buffered, and this might affect performance.
Should the endpoint 1 size also be fixed? The register has it at 4k, but it
wasn’t an 8k buffer.
No, because High-Speed BULK will only use 512 byte packets, and 4k is
reserved for isochronous, which doesn't need double buffering at the moment.
