I thought I replied to that. This product's pages open only in German even if I search on the English site. So could not find where to ask. For the encouraging words, thanks. I'll keep it up. As I mentioned the glaring gaps between wireshark and usbmon and quality issues with the former are disappointing and so is the word length limit in usbmon. Next time I take this up, I'd use the binary interface of usbmon to get more reliable (hopefully) and complete data - probably next weekend. Also, will try and call ioctl directly in C when experimenting to avoid any possibility of pyusb doing something wrong (this is not meant to suspect so, just reducing the layers in between to reduce things that can possibly hinder something). Will try and ask on sane mailing lists in the meantime. Thanks for the suggestion and all other pointers.
