USB footswitch

[Michael Culley]

I've made a footswitch that works off the serial port of a PC but the problem with it is that it needs an external power supply. I
would prefer to convert it to USB but have no knowledge of USB. Can someone tell me what's involved? I'm currently using an Atmel
2051 chip. All it needs to do is determine if a few switches are open or closed.

Is there a chip available that will interface the 2051 to USB. Cost isn't that important because the overall package of software/pc
will be a few thousand dollars.
What is involved in writing software, I'm using C# but could write a dll in C if needed.
Do I need to purchase a USB manufacturer ID? Can this be avoided?
How much will it cost me to get it all done. Depending on the cost I'd probably just prefer to pay someone to do it. If anyone is
interested mail me at news at mikedriveway.com

Cheers,

You may find an easier way is to look at what "footswitch usb" pulls
up on Google - certainly if you are thinking about "transcription"
foot switches the Olympus one might be the go.

A company I have worked with before have one they sell - probably
manufactured in China. It is used for PC based transcription.

Personally, I hate reinventing the wheel, so for a few things where I've
needed to interface to a computer for pushing buttons i've modified
keyboards - that way all the circuitry is there, the driver is there, i just
have to write my code to react to certain keys.
