Controlling USB devices from C#

[Miguel Gómez]

Hi, every body!

I would want to know, if is there any way to control an USB device ( a code
bar reader, for example) connected to the PC, using C# code (or VB). I must
be able, for example, to disable reading, and, depending on the bussiness
logic, enable it again, using C# or VB code.

Does such a class exist in the .NET Framework?

I sicerelly appreciate any help in this subject.

thank you

Mike
