Hi,
I am having the same problem with "USB Device not recognised"
My circuit is the same except i have not connected the LED's and i have connected MCLR & RA1 directly to Vdd
Do you think this could cause the problem?
Thanks
Martin.

Have a look in the usb forum, there are one or two other suggestions there if you have not found them already.

Matt,
Very helpful article. Thanks. Note that #develop (www.sharpdevelop.com) makes for a free open source development environment for C#. I found it made a good environment for your code.

Dave,
I've heard about sharpdevelop before but never had a need to use it, due to having access to C#.NET, glad to know it works though. If you want another alternative free dev enviroment try C#.NET express from microsoft, works a treat with the code also.
