I do and have done similar stuff. For example for a Teeny 3.6 and now T4.x that have the ability for USB Host setup, I often try to capture the USB data transfers and try to get the data into a format maybe more similar to what WireShark or Beagle USB 12 might output. (Wish we could do the 480, but that is probably wishing for too much).

I have mentioned it in a few of the different threads, including: [Logic 2.1.5 (Alpha 17) - #17 by Emmanuel](https://discuss.saleae.com/t/logic-2-1-5-alpha-17/252/17)

And I know that one of the Saleae developers was working on being able to do an HLA doing something similar:

I know I mentioned earlier about USB capture stuff, (USB LS/FS analyzer) and mentioned, that I wish I had more control over what things that showed up in the decoded protocol and later output reports. I use this analyzer when working with Teensy 3.6/4.0 USB host code support. Often when I wish to help support a different USB Mouse or Keyboard, Joystick, Serial Adapter,… Often times I try to analyze the communications that hap…

> Hi Kurt. The work involved for the HLA will be more involved than I originally expected. It will require adding HLA support to the USB analyzer, which is one of our more complex analyzers (if not the most). I’ve added partial support, but unfortunately I won’t have more time to complete it this week. I’ll let you know once I have time to revisit it, but it’s on hold for the moment.

I don’t remember if this was ever added to the feature requests and/or if any progress has been made since then.
