According to this wiki page, USB (at least for 1.1) is doable on my board, but I can't make sense of the two pictures and the accompanied instructions attached in that page.
Is there a place I could find more detailed/clear instructions on how to do this? Also, from those who have attempted this or have it installed and functioning, does it affect the stability/performance of the device? Are there any pitfalls I should be aware of before attempting this?
