Hi Ronnie,

I'm only vaguely involved with Linux USB but I have spent some time 
experimenting with the Linux USB/IP implementation by Takahiro 
Hirofuchi (http://usbip.naist.jp).  Does Wireshark have any support for that?

I have never been involved with reverse-engineering a Windows USB 
protocol, but from what I hear people are happy to use a Windows 
program called "USB Snoopy".

However, the Linux USB/IP mailing lists (sourceforge) have questions 
from people asking about communication between Windows USB/IP and Linux 
USB/IP, for example so that a "USB server" running on something like an 
NSLU2 can serve printers, scanners etc to Windows machines.  From this 
point of view, it would be interesting to know what wire protocol these 
Windows USB/IP devices use.

(BTW, I am curious to know how many Linux USB developers actually have 
access to an analyser: I have considered various hacks that could be 
used to build a homebrew analyser, and wonder how much "supressed 
demand" there is for something like that....)


Regards,

Phil.
