the latest bk revision of drivers/net/usb/pegasus.c seems to agree with
you. From the changelog
- Stop log spamming ... at least some of these chips seem
to get confused about data toggle, no point in warning
about each packet error as it's detected.
I also asked one of my colleagues to try the dongle on another of our
boards with an OHCI controller and we saw EP3 toggle errors there as
well.
