Description (last modified by pulkomandy)

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

00000000000000000000000000000000000000

The output on the other machine shows things like: 

11111111111111111111111111111111111111

I the log files we see lines such as: 

KERN: usb error ehci -1: qtd (0x708fb00) error: 0x80068d52

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