It was originally a Kickstarter campaign, perhaps the oldest one to be reputed for delivering spectacularly late. Only several hundred of these were ever made. The oldest and probably best of these is OpenVizsla. They also have USB3 models starting at $5000, but if your devices are USB2 then you don't need that, since they'll only use the USB2 part of the USB3 connector.ģ: Use an experimental, (probably) not-so-stable open source hardware analyzer. You can use a 2nd computer to capture, which avoids loading the machine under test. The Beagle480 from Total Phase is the one I use. But if you are monitoring already-working USB devices or experimental devices built with already-debugged USB code, which are only connected to your own PC, this can give pretty good results.Ģ: Use a mature, stable, well supported hardware analyzer. It can't monitor between a board like Teensy and other devices. It can't capture many types of mal-formed packets and transfers. Just to make sure you get a clear answer, no, Teensy's USB port does not work that way.įor capturing USB packets, you have roughly 3 options.ġ: Run software-only capture on the same PC.
When the developer rolls-out an app update with unintended consequences, I would like to capture and document what’s different when I roll-back the update thank you.Ĭan Teensy be used to see and capture USB traffic? I would like to document baseline comms for 17 different applications. I can capture TCP/IP packets via wireshark. * PC ETHERNET PORT TO ETHERNET SWITCH PORT = * PC USBv3.0 TO BAR CODE SCANNER v2.0 PORT I would like to capture traffic as follows: HP PRODESK 600 G1 SFF PRODUCT - # K1K49UT#ABA I want to setup a usb testbed for the following:
