Is there a usb trace tool in mac like USB Trace or Bus hound in win os ?
The developer tools include USB Prober.
I know it. But it seems that USB Prober can not catch usb data when plugging a custom usb device.
I would go to the Wireshark forums and ask your question. I know Wireshark can do it, I don't know about the situation your specifically looking at.
Wireshark is used for network data analysis,but I am looking for usb data analysis tool in mac.
A simple google query proves the opposite - it's a very versatile application ;-)
Huh, I didn't know that either. It's been a staple of mine when I play with low-level network protocols. But too bad it seems to only work when the device is plugged into Linux.
I guess this raises the broader question. How do people developing USB drivers for Mac generally debug them?
You need a debug version of IOUSBFamily.kext for the USB Prober, that output log information. More about that here: http://developer.apple.com/hardwaredrivers/download/usbdebug.html
On that page you also find a link to a Q&A about USB development on machintosh, with information regarding 3rd party USB analyzers, both hardware and software.
There are 4 companies mentioned in the Q&A.
Thanks for indulging me Subsonix. Perhaps this is the route the OP should also use.
