Re: Controlling USB devices from C# -

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? |

However, depending on the device that you're trying to control, there is a
good chance that the manufacturer will instead provide an AP to call.
That would probably be easier than trying to talk to the USB device
yourself.

You'll have to turn to the Win32 API.
If you just want to enable/disable the driver (like right click->Disable in
Device Manager) there is a standard way to do it.
If you need to communicate with the device itself, then you'd need detailed
information on the particular device.
