The proper working environment for USB development is a recent 2.6 kernel. Don't use Linux 2.4. Which distribution you use isn't important. In the end you will want your work to apply to a vanilla kernel from kernel.org anyway. > Also, I've seen quite a few patches float by since I joined - is there > a list of essential patches for USB hacking? If you're going to change the core or an existing driver, you will want to have the most current patches installed. For USB, those patches are located at http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/ in the gregkh-all patch sets. If you're going to develop a new driver, having the most recent patches doesn't matter so much. It would be okay to use the 2.6.14 kernel.
