Paolo, do you have any comments on the changes?

The only issue I see is the following:

I think that the following line is not good:
622c693
<       pkth.len = info.hdr->urb_len + sizeof(pcap_usb_header);
---
      pkth.len = info.hdr->data_len + sizeof(pcap_usb_header);

The 'packet length' (that is: the length of the URB associated to the current usbmon event) is definitive
info.hdr->urb_len + sizeof(pcap_usb_header), while the latter is the number of bytes effectively available.

ciao,

Paolo
