- Add more fields for USB device and host mode - Add more information to USB PF header so that decoding can easily be done by software analyzer tools like Wireshark. - Optimise usbdump to display USB streams in text format more efficiently. - Software using USB PF must be recompiled after this commit, due to structure changes. MFC after: 7 days Approved by: thompsa (mentor)
