Did you try my new driver?

What I do to look for errors is examine the error counters using either=20
ifconfig or better yet /sys/class/net/irda0/statistics
and run irdadump and look for whether data is having to be retransmitted=20
all the time.

When I was testing with my PDA, I saw that the stir4200 needed a=20
turnaround delay otherwise it couldn't
go from transmitting to receiving fast enough.
