Alan Stern ba516de332 USB: EHCI: check for STALL before other errors ... This patch (as1257) revises the way ehci-hcd detects STALLs. The logic is a little peculiar because there's no hardware status bit specifically meant to indicate a STALL. You just have to guess that a STALL was received if the BABBLE bit (which is fatal) isn't set and the transfer stopped before all its retries were used up. The existing code doesn't do this properly, because it tests for MMF (Missed MicroFrame) and DBE (Data Buffer Error) before testing the retry counter. Thus, if a transaction gets either MMF or DBE the corresponding flag is set and the transaction is retried. If the second attempt receives a STALL then -EPIPE is the correct return value. But the existing code would see the MMF or DBE flag instead and return -EPROTO, -ENOSR, or -ECOMM.
