I need to do some radiated susceptibility testing on a harness which among = other things contains a 4 port USB 2.0 hub. What I'd like to do is have a P= C USB host generate a series of test patterns through the hub, read them ba= ck from the downstream side of the hub into a second port on the PC and do = a binary comparison, logging any errors. I could write some code to do this= myself, but I was hoping to save time and just buy or rent something to do= this. Anyone have any ideas? I sort of assumed that this would be a common= type of testing for USB cable manufacturers and such, but haven't been abl= e to find anything.
thanks,
Bob
