If you have purchased a Virgin Mobile Broadband2Go pay as you go aircard (actually a novatell wireless ovation MC760), and find that the driver installation hangs on Windows 7, you will also find that the internet is little help.

The solution is to disable USB Selective Suspending until Virgin Mobile releases a driver version later than 2.02.04.002

Here is the link to the release notes for the OQO drivers – which are newer that either the Virgin Mobile or Novatel generic drivers.

You disable USB selective suspend from the advanced power settings screen.
