Which book to buy

[Larksman]

Hi Jan,  I have built a hardware project on a Rasberry Pi using C to control the devices.  I want to be able to access the low data rate output in a c++ program on a Windows pc via usb.  Which of your books is going to give me the most help with this?  Michael

I would start by learning what USB classes your device supports.

USB Complete will help you understand USB classes and communications. The host examples use C#.
