Yeah, that is not an easy one to find.  Unfortunately the USB spec does 
allow control pipes to be non-default (i.e. not endpoint 0), and there are 
device manufacturers who build devices with non-default control endpoints.  
I personally don't see the point, but javax.usb had to handle the case.

For the TCK testing, we used a D-Link DSB-V100.  I just happened to have 
one and I knew it had a non-default control pipe.  As far as finding 
another device with a non-default control pipe, I don't think 
manufacturers provide information like that, you'd have to actually buy 
something and connect it up to look at the topology.  You may be able to 
find a programmable USB test board that can support non-default control 
endpoints, however not all of them support that.

You might be able to find a DSB-V100 on ebay...


I'm also curious, do you have a javax.usb implementation for another 
platform that you are testing?  Have you got all the other TCK tests to 
run successfully?
