USB device bulk transfer benchmark

About

usb_dev_bulk is a utility for measuring the performance of USB bulk transfers to and from any USB device. It was originally written to test the performance of libopencm3 drivers for the USB stack.

Usage

• -c | --copyright: -- print license and exit
• -d | --device -- device to test, in the form VID:PID (i.e. c03e:b007)
• -e | --endpoint -- endpoint to use for bulk transfers
• -I | --IN -- use IN transfers (default)
• -O | --OUT -- use OUT transfers
• -s | --sync -- run transfers synchronously (default)
• -a | --async -- run transfers asynchronously
• -q | --queue-depth -- number of simultaneous transfers to issue in async mode
• -t | --transfer-size -- length of each transfer

Examples

Asynchronous EP2IN, with 1024 byte transfers and a queue depth of 32

$ usb_bulk_bench -d c03e:b007 -e 2 -I -a -t 1024 -q 32

Synchronous EP2IN, with 1024 byte transfers

$ usb_bulk_bench -d c03e:b007 -e 3 -I -s -t 1024

Building

Prerequisites

• gcc or any working compiler
• cmake
• libusb

Working with cmake

1. Create a build directory and cd into it:

$ mkdir build; cd build

1. Now tell cmake to crate the build system, pointing it to the source directory:

$ cmake ..

1. Compile:

& make

1. Profit
