If anyone has any objections, please let me know. ------------------ From: Chris Brandt commit dd14a3e9b92ac6f0918054f9e3477438760a4fa6 upstream. The timeout for BULK packets was 300ms which is a long time if other endpoints or devices are waiting for their turn. Changing it to 50ms greatly increased the overall performance for multi-endpoint devices.
