I have had a few reports that people are having issues with the USB drivers on Windows XP.

The problem

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.


  • Make sure you have Win XP SP2 installed.
  • Get the latest .NET Gadgeteer bits. Probably from GHI, and remember they are updated often; probably fixing some other issue you may hit!
  • During the install select the ‘Legacy USB Driver’ option.
  • Plugin your mainboard (spider) and in device manager right click the unknown/error device and update the driver to a legacy driver. (located in the GHI install directory) – something like
  • “C:\Program Files (x86)\GHI Electronics\GHI Premium NETMF v4.2 SDK\USB Drivers”
