API is the best feature
The API is amazing. Whilst the Beagle 12's DataCenter is limited in terms of decoding, I simply extended the multi-platform capture_usb12 example code. I now have class level decoding and proprietary protocol decoding for a few extra hours effort. Fantastic!

Best bang for $
This is an outstanding hardware USB analyzer for device troubleshooting.
Ordered the wrong item, RMA process went very smooth. Ordered the correct items, all work great.

Like the device, needs more documentation
It would be helpful if more documentation was provided for the device. A 'go by' of the analysis of a standard USB conversation with a Microsoft product for example would be very helpful.

Everything it should be.
The Beagle 12 was essential in getting our project finished on time. We should have bought this from the start rather than waiting until the very end. If you are writing a USB stack, you should own a USB analyzer. And this one had everything we needed for our project. We didn’t need more. Nor would we have been able to finish without it.

Beagle USB 12
Not really much to say. The Beagle USB 12 does exactly what it advertises to do. Without it, my job would be a whole lot more difficult.
