Beagle USB 480 Protocol Analyzer
The analyzer itself works great, it captures all traffic in real time and it is very easy to connect it. However, the Data Center Software for PC does have issues which slowed us down considerably because we were not aware of them. It sometimes does not order the USB packets correctly, showing some packets that were transmitted later above the packets which were transmitted earlier, instead the other way around. So if the sequence of packets is, for example: IN(NAK), OUT, SOF, IN, the software would show OUT, SOF, IN(NAK), IN, which is not the expected behavior. It took us a whole day of thinkering why the packets were being sent that way before we figured out the it was just the software showing them incorrectly. The absolute timings are correct though. We don't know if this is a known problem, but we have a proof that it can happen on Data Center v7.01.
Used for hobby.
Easy to use.

Amazing tool and student friendly company
I recently purchased the Beagle USB 480 for some embedded research that requires some advanced features such as high-speed USB monitoring combined with hardware I/Os for triggering other test equipment. On the HW side I am very happy with speed and resolution of the Beagle 480. I have found the SW very intuitive and easy to use and I am constantly discovering new features. Finally, I would like to mention the great support I received from TotalPhase previous to purchasing the device. I requested a quote and inquired about academic pricing and received an immediate response (from great sales agent Karen). As a grad student on a tight budget I really appreciate a company like this. I highly recommend the Beagle 480 and TotalPhase. Thanks, Gabriel

Amazing: I had an older C# program for the SPI-Beagle, just changed a few lines and it worked for the USB-Beagle. Same API, same programming interface, same concept behind. Great!

Nothing short of epic...
This little but amazingly powerful device has saved my technology startup. I had such a hard time finding a contract firmware developer with experience in USB that I had to become my own. This tool has proven itself priceless when it comes to debugging and improving our company's prototype. We are now back on schedule thanks to Total Phase!

It is sad that you confined to send to Russia packages that cost more than $270.

A very useful tool
Money well spent

Does what it should
Needed to debug an embedded full speed USB connection (no USB cables, devices are both on board.) Was able to cut a USB cable in half and solder wires to the signals and plug the other end into the Beagle. Worked like a charm. At full speed, wires didn't need to be too short, making it easier to solder. Software is all right, but had to read the manual to really find everything I wanted. Total Phase customer support is excellent.
