Thanks for pointing it. It seems very interesting. Paul, On a quick test, it seems that it doesn't recognize the tcpdump file format (at least, it was not able to capture the dump files I got with the beagleboard). Adding support for it could be an interesting addition to your code. Btw, it seems that most of your work is focused on getting VMware logs. Most USB adapters I handle are USB 2.0 only, and have very high bandwidth requirements (something like 40%-60% of the total bandwidth available at the USB bus). It would be nice to be capable of using a VM on some cases, but the last time I tested VMWare, kvm, etc, none of them were capable of properly support USB 2.0 with isoc data transfers. Do you know if any of them are now capable of properly emulate USB 2.0 isoc transfers and give enough performance for the devices to actually work with such high-bandwidth requirements? >> I know you are doing this in console mode, but it looks close to the >> same idea. Yes, there are some similarities, although I think that the tools complement each other. Doing it via console is nice, as I can just use the serial interface of the beagleboard to capture and parse data in real time. An offline graphic analyser is interesting, especially when you need to filter data and check event timings. > Perhaps there should be some references to vusb-analyzer and similar > tools in Documentation/usb/usbmon.txt (it now only mentions "usbdump" > and "USBMon").
