Subject: [usb] timeout
Hi,I would like to ask about timeout values in usb 2.0 core, why these are
622 ns FS(7.5b times) and 400 ns HS (192b times)?
Shouldn't these be 18 bit times in FS and 816 bit times in HS as stated
in 7.1.18 of usb spec (end to end delay)?
And how timeout is checked? Is timeout counter started when linestate
enters squelch level (or SE0 to J transition for FS) and reset when
linestate leaves squelch (or J to K transition for FS), when device waits
for data or response from usb host)?
