This project is a USB 2.0 high speed (480mbps) capable bus capture device built from a low cost FPGA development board and USB 2.0 PHY evaluation board.

The FPGA development board is the miniSpartan6 , based around Xilinx Spartan 6 LX9 (there is also a LX25 version available), which has 32MB SDRAM, FTDI USB 2.0 interface, SPI Flash, SD card, 2 HDMI interfaces and numerous digital and analog I/O connections for expansion.

The USB 2.0 PHY interface is based on the SMSC/Microchip USB3300 which is a ULPI based high speed USB PHY. The 'USB3300 USB HS Board' evaluation board has both USB A and USB B mini connectors which are wired together, making it suited to constructing a cheap USB bus analyser from!

The miniSpartan6 is available from https://www.scarabhardware.com/minispartan6 for $75 and USB3300 PHY board is available from http://www.waveshare.com/usb3300-usb-hs-board.htm for $9.

• Support HS (480mbps), FS (12mbps) and LS (1.5mbps) captures.
• Supports continuous streaming, one shot and detects buffer overruns.
• Dense logging format that is expanded on the host PC.
• Filtering based on match or not match of device ID and/or endpoint
• Filtering of SOF packets (which are every 125uS in HS USB, 1ms in FS USB).
• 0.5uS timing resolution (HS) or 4uS timing resolution (FS/LS)
