C# and universal serial bus (USB)

hi-

I have spent hours in MDSN and I couldn't find any efficient method for communicating with USB using C#.

I want to create an application to select an MP3 and send it to the circuit I have designed and connected to USB (AM modulator), and then receive and play it with a regular radio. so I need to define the USB to C# and I don't know how to do it.

regards

Here you go

@evildictaitor:

thanks, but I have already tried that. 

no satisfactory results!!!

try this out:

PS:  USB via .net can in some cases need a bunch of work.

I'm new to USB programming on .Net as well. Specifically I need to communicate with this IO controller. The way that one works is that it uses a "CDC USB" driver that makes the USB port look like a regular old serial port, meaning the SerialPort class can be used to easily communicate with it (although don't be fooled by baud rate, stop bits etc as I believe it just ignores those settings - bandwidth is not limited to the baud rate).

That controller came with its own driver but I'm sure you might be able to find a generic driver that can make the USB port look like a serial port. Look here for some info in CDC drivers.

USB Serial is good for a lot of stuff but then you lose a whole lot of what USB can do.

just depends....

True. That last link I gave shows a lot of different USB drivers you can use depending on how you want to use it. The CDC driver is just for the most basic read/write type of access. The advantage it has is that it already has .Net support. I'm not sure how many of those other drivers have .Net support.

Recenty i needed to talk to a USB Printer (not a normal desktop printer, a special Point of Sale /Kiosk One) and found it a real pain. I wish there was a better .Net library for that stuff.  the one i posted the link for can work but the developers are way more into custom device stuff and have no real info for just starting out ... they speak USB and C++ more than C# and .Net ... at least that's the best i can explain it.

@figuerres:POS for .Net?
