Are there any networking tools available (even 3rd party) that will 
collect & display
the tcp/udp/ip statistics (e.g., packets sent, packets received, 
errored packets, etc.)
on a per-interface level?     I'm trying to analyze some USB networking 
problems from
a host-to-host link (running UDP/IP over the USB), and need some way of 
monitoring
for networking errors across this link.

thanks for your help,
Dave
