We have one that is enumerating but there are FIFO errors being reported by
the pxa270 that we haven’t been able to eliminate. A USB bus analyzer
doesn’t indicate any problems with NAKs and retries during the enumeration
process but the pxa270 has reported a half dozen FIFO errors during the same
interval. So I’m just curious if anyone else has seen this problem or may
have insight into what could cause it. The Intel docs give four instances
when these FIFO errors will occur but it doesn’t seem like any of them could
happen in our code (not that they aren’t). The errors are easy to ignore but
I don’t want to mask a problem.
