USB Development Tools for Embedded Devices?

engywook asks: "I am thinking about putting a USB interface onto a real-time (home-brew kernel) embedded device, (naturally) with the intent that it talk to another device. I am thinking that it would be very useful to be able to monitor the USB traffic between my device and the other device, and between that other device and (say) a PC that already knows how to talk to it. Looking around, it seems that this capability is available, but at prices in the US$10K and up realm, which is a lot more than I can afford. I am looking for pointers to tools that would accomplish this for much less money. Any ideas would be appreciated! Thanks!"

Cypress USB Kit

I bought a Cypress USB kit a few years ago, it's quite cool. Is that company still in business? Their website seems to be gone.

Yes, I'd also found USB Snoop. I think that it also may be of use in the early stages.

You are right that there is a node=to-node relationship. In fact, I expect that my device and the other will be the only two connected at any given time. Unfortunately, I don't get to pick the interface. The other device already exists, at it is already USB.

BTW, the only reason it is USB instead of RS-232 is that "someone" convinced (nearly) all the PC hardware manufacturers that RS-232 was Evil and USB was Good. So, PCs no longer have RS-232 ports. So, the manufacturers of the device I have to talk to are discontinuing their RS-232 versions and coming out with USB versions. So, we have to talk USB, too, even though the RS-232 stuff was working just fine. sigh.
