The FTDI chips are really easy to use !! They can do JTAG too (don't know if the ISP1362 can do that ) . And you don't need to understand the USB protocol at all ! It's almost a plug & play device .

Thanks for the reply.
I understand that the FTDI chips allow for ease of use, and think that it's great and we're lucky to have something so cheaply available to us.
But I want to learn the USB protocol, I want to build something that log all of the actions and interactions between the host and the device, so that i could learn and understand how USB works.
It might take ages to learn, but I'd still like to try.

The ISP1362 seems to be a bit more difficult to configure ... Have you searched the forums about this USB controller ? Doesn't seem to be as popular as the ftdi devices though ...

Yeah, I've done a bit of searching, it seems that most topics are about getting USB working on uCLinux. I'm not sure that writting HDL for uCLinux would be the same as writting a device mode description.
