From the USB 2.0 spec: 5.5.3 Control Transfer Packet Size Constraints An endpoint for control transfers specifies the maximum data payload size that the endpoint can accept from or transmit to the bus. The allowable maximum control transfer data payload sizes for full-speed devices is 8, 16, 32, or 64 bytes; for high-speed devices, it is 64 bytes and for low-speed devices, it is 8 bytes. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
