[Note: Firmware, versions and hardware will change over time and I expect this guide to get out of date, it is intended to help those with 4.1 –> 4.2 migration issues.]
I have had a few reports that people are having issues with the USB drivers on Windows XP.
When a mainboard (spider) is connected the USB driver never loads, the device is not found and VS cannot deploy. If you look in the device manager it will appear as unknown.
.NET Gadgeteer now supports v4.2 of NetMF, which means that you can now code in VB! For those of you that use the Resources feature you may notice that there is a slight bug.
For example importing and using an image as a resource does not work as expected (if you come from C# land).
