The port works fine with anything else. Go figure.
Settle a bet, are you running Windows?

Does anyone have experience with the Papilio one? https://www.sparkfun.com/products/11158
I have one, and I have it setup to run the ZPUino softprocessor. It is very cool, especially with the VGA output arcade shield. Unless you are an FPGA wiz you will have a headache getting other IP cores to port over.

I would start with this book : http://www.amazon.com/FPGA-Prototyping-VHDL-Examples-Spartan-3/dp/0470185317/

and a starter prototyping board from diligent: https://www.digilentinc.com/Products/Catalog.cfm?NavPath=2,400&Cat=10&FPGA

Design using VHDL is difficult and time consuming because it isn't very incremental. Commonly everything has to be 100% laid out and perfect for anything to work properly. Build and Simulation times are very long (multiple minutes).

If you want to have fun learning FPGA dev, start small.

So, I've always been interested in embedded programming, since it's so far removed from what I do (web development). I'm thinking I'd like to buy a board and gently caress around with it, but I don't have any ideas for projects. So I'm wondering, what kinds of DIY projects you guys have been working on with your Arduinos and Teensys (Teensies?) and whatnot?

(fwiw, I'm thinking of making a "light show" sort of thing that can take audio and blink lights to the beat or something, which seems doable with Arduino)

I was curious if I was able to spot windows USB behavior. It's like each root-hub is it's own island, and a device can become unwelcome on that island.

Retina MBP.
Windows (for *all* of its faults) is really great about having turnkey solutions to new technology. Getting certain MSKinect toolkits to compile/install in linux is a complete nightmare. In windows there are three .MSI files to click and we're running. I have a dedicated windows laptop as my Kinect manager for my projector installations.

Also, when OpenCL was "first released" it was nearly impossible to get an NVidia card properly configured in Linux to work with it, so I had a windows box to learn OpenCL development on.

About to purchase an Altera DE0 nano board. Am I getting myself into trouble?
I know nothing about FPGA and hardware design and I don't really understand HDLs.

Also what's a good book on hardware design + vhdl/verilog? Preferably something that doesn't shy away from the math.
Get a spartan S3 (http://www.xilinx.com/products/boards/s3_sk_promo.htm) and this book http://www.amazon.com/FPGA-Prototyping-VHDL-Examples-Spartan-3/dp/0470185317/

The DE0 Nano is good if you kind of already know what you are doing.

 FPGA boards are not cheap. The time you spend banging your head against the DE0 will be that $110 dollars 10 times over.

The S3 board also has a lot more features, and is more suited to actually learning.

http://www.digilentinc.com/Products/Catalog.cfm?NavPath=2,400&Cat=10&FPGA - here you can get it for slightly cheaper, and if you are in school you can get it for $159.

Unless you know exactly what you want to do with it, the DE0 is best suited for collecting dust on a shelf. It's cheap for a reason.
