USBPcap to capture RF Air Interface data. However, my device is in fact a USB serial device, so I turned to Portmon which can sniff serial port traffic without the USB overhead. It produces huge dump files, but everything is there. It works under Windows XP (but not later) and has a much nicer GUI than earlier versions. This is a great tool that finally brings hobbyist-level USB analysis up to Full Speed USB. USBPcap is open source USB software sniffer for Windows XP, Vista, 7 and 8. For USB traffic, it seems that SniffUsb is the clear winner. Software solutions on a PC obviously won’t work because doesn’t even know if he’s sending valid USB packets. Sniffing USB Power Delivery traffic on both Control Channel lines (CC1/CC2) Transparent interposer on a USB Type-C connection Monitoring VBUS and VCONN. Our first USB traffic sniffer and protocol analyzer was the ezSniffer, an add-on to the commodity EZ-USB FX2LP board. This is a rather novel device V-USB is limited to Low Speed USB, and other USB capture tools are far out of reach of the hobbyist budget. The miniSniffer2 is a hardware packet capture and analysis tool for inspecting and debugging USB connections to Full Speed and High Speed devices. The logging and analysis board attaches to this dongle, and uses a rather fast ARM microcontroller to listen in on USB packets and send everything over serial to a PC. The first is either a dongle or a pass-through device that simply serves as a tap between a USB device and a USB host. The design of this USB Packet Snooper is split up into two parts. This multimedia dial is bitbanging USB with an STM8, which means needs a tool to capture raw USB packets. It’s kind of like the Microsoft Surface Dial or the ubiquitous Griffin PowerMate that has been on the market for the better part of two decades. is building an HID Multimedia Dial for this year’s Hackaday Prize. It’s a small device that allows for capturing and analyzing Full Speed USB traffic to debug one of ’s other Hackaday Prize entries. This is exactly how ’s USB Packet Snooper was created. Sometimes you run into a few problems when developing your own hardware, and to solve these problems you have to build your own tools.
