Hello, Background: I'm running an experiment that is sensitive to USB latency of a few milliseconds. During a typical overnight run I encounter a handful such "high latency events" and I am trying to understand why they happen. If you can recommend kernel settings/hacks that will decrease USB latency, please share! === Question: How can I retrieve a count of USB transmissions that failed or were retransmitted (similar to ifconfig on ethernet)? I am using bulk transfers. If you do not answer this question, can you instead recommend documentation that will shed light on the subject? Can you recommend somewhere else for me to ask this question? Thank you!
