USB communication between VB and an 18Fxx31 device

[HenrikOlsson]

Hi,
Well, the 18Fxx31 series doesn't have USB on-board (like the '2550 etc) so you'll have to use an external USB chip. Something from FTDI, like the FT232R is probably a good option. It's nothing I've played with personally but it's being done 'all the time'....

Or perhaps something as simple as:

Gets around having to solder SMD chips

Sure, if you're building one or a few units or for experimenting it's definitely a good approach. If building several units then the cost compared to buying the IC, connector and supporting components adds up. Sparkfun also has several similar products, based on various IC's.
