[PATCH 031/229] USB: cp210x: increase bulk-in buffer size to 256 byte

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johan Hovold <jhovold@xxxxxxxxx>

The cp210x requires a bulk-in buffer larger than endpoint size to keep
up at high baudrates without loosing data.
