Jason Wessel 815e173e1d USB: ehci-dbgp: split PID register updates for IN and OUT pipes ... This patch addresses two problems: 1) Bulk reads should always use the DATA0 for the pid, and the write PID should toggle between DATA0 and DATA1. The fix is using dbgp_pid_write_update() and dbgp_pid_read_update(). 2) The delay loop for waiting for a transaction was not long enough to always complete the initial handshake inside dbgp_wait_until_done(). After the initial handshake the maximum delay length is never reached. The combined result of these two changes allows for the removal of the forced resynchronization where a bulk write was issued with a dummy data payload only to get the device to start accepting data writes again.
