.NET 2.0 & USB support?

[Claus Konrad]

Hi

Anybody got an impression whether .NET 2.0 supports USB ports?
I know that the Serial (COM) and parallel ports (LPT1) are included, but how is the story on USB ports?

Claus,

There is no support for USB devices out of the box. You will have to use COM interop or P/Invoke to make calls to unmanaged APIs in order to access this functionality.

Hope this helps.

What exactly do you mean with "support"? All device access in Windows goes through device driver interfaces, while the device drivers can only be implemented in C , all user code should be able to access the device, irrespective the implementation language. The way this is done depends on the device type itself, f.i to access a generic USB Disk device one can use the IO namespace classes. However if the device is a non generic device, one should access the device through it driver interface using CreateFile and DeviceControl Win32 calls. If the device manufacturer has added support for higher level language interfaces like COM (or .NET) you can use COM interop to access the device.

Wlily.
