USB port

[Aaron]

Im new to .net. I would like to upgrade an existing application to .net and
add USB support.
How do i write a .net application with USB support?
We used "mscomm" in vs 6 for serial (rs232) ports. Is there a similar driver
in .net for USB ports? any tutorial page out there?

Thanks in advance,
Aaron

USB is a /bus/, not a port. Typically communication with a special device
is done over DLLs/drivers provided by the connected device's manufacturer.

so how can i read data from the usb port, since i am the device
manufacturer.
for serial ports i just need to load the mscomm.dll and start reading.

There might be other products like DriverX USB.

Hi

If you've been using mscomm, then following this link:

will get you started - Dick Grier's website / book are a good place to get
the information you need.

If you're saying that you can just treat the device like a serial port, then
there's a number of libraries out there that provide serial support for
..NET:

Here's one that's supposed to be very similar to mscomm:

but how do you treat the usb port like a serial port?
im very suprised by the amount of documentation available on this topic. i
thought there would be a dedicated class in the .net framework for this
purpose, since most devices use USB nowadays.

I think the problem is that writing a USB driver is still a low level
function - .NET 1.0 doesn't expose enough low level functions to allow you
to write a USB driver effective. As a result, you need to write the USB
driver in a language like C++ and then expose the device via an API to
..NET. In short, I don't think you can access USB hardware directly without
an interface or a specialized component like DriverX for USB.

Hi,

You can use any serial port methods. You can download NETComm.ocx from my
homepage, for example. There are a number of .NET serial port classes
available for download, and I have one in my book, with lots of examples,
naturally. Also, there is a .NET serial dll in the Visual Basic Developer's
kit, which is available from Microsoft (free download).

There is a low level USB library for .NET:
