Old description:
usb_serial seems to occasionally insert control characters and also seems
to lose data.
To see the problem we have two machines linked with a serial cable,
running at 57600 baud.
On the Haiku system we am sending simple ascii files, repeatedly, such
as:
11111111111111111111111111111111111111
22222222222222222222222222222222222222

The output on the other machine shows things like:

I the log files we see lines such as:

On OHCI we may not have seen the corruption, though the loss of data
still occurs:
