i know it sounds weird, that because i did not explain my project exactly, thanks for the help

It sounds like you are not very clear on the project.

If all you want is the computer to recognize a device then take any old device and the computer will recognize it. That part of the project is done. You just need to write a new driver and app which do what you want instead of what the original driver did. There, problem solved.

 

Michael,
If you can't already tell many of us have short fuses around here for new people who are provided with information that would be very beneficial for them to learn about yet they refuse to take the 5 minutes to actually read and learn instead of just expecting it to be handed to them on a silver platter.

This site isn't for free Engineering services... We try to help.. But we aren't going to do it all for you for free.. Let alone for a product that you may make money on..

 

Ok maybe i will have to explain better,
lets say i want to make a fast discharge component for android devices. of course this is stupid but lets say that. now i want to open a battery stats app that i maid when the discharging cable is connected (lets say its just a resistor between +5V and GND). i will short the sense line to GND to cause the phone to output power (OTG) and thats it. now i can make an app with the usb host mode android api. if i understand correctly all i need is to put the usb ids on the app (in the correct xml file.. blah blah) and the rest of the app is just stats of the battery. now what is the best way to present usb ids on my free D- and D+ data lines so that i can define my app to open when a usb "device" with these ids is connected?
again, thanks for trying to help.

 

you need a flux capacitor

 

you need a flux capacitor

And you only have TODAY to get it...

CUBS WIN....!!!! Horray
Oh Marty...
Doc?

Jokes aside, here's an idea. Some USB memory sticks (specifically those of the kingston brand) have a unique serial number that can be read with a simple app that you could write in .NET, for instance. You could use that memory stick as the key that will activate whatever routine you want in your computer, assuming your app will constantly monitor your computer's USB ports.

 

flux capacitors are illegal to manufacture in china

 

of course this is stupid

I think some of us had already come to this conclusion.

 

Mostly because they haven't been invented yet.

Yes i thought about that, but i want a general solution than i can produce in large quantities. i want my own simple way to identify my "cable". i understand that maybe there isnt a way, at least without deep learning, but i thought its worth to try asking. Tanks again

 

Well first you are going to have to get a license to produce USB devices with your "name" it only costs 5000$.
After that computer needs to know VID & PID identifiers so it can recognize the device in case that you want to use HID interface,in case you dont want to use HID you will have to write your own Drivers.

for you i will change my story to "i want to make a portable finger warmer" (the resistor will make that anyway)

 

You might be able to use a device like an FT232R. It does all of the heavy lifting of talking USB and then converts it to a UART interface.

You may still need the microcontoller but you will not have to know how USB works.

getting a license is one option, and i also thought about another option, which is, if ill have to use a microcontroller anyway, so its VID and PID exists already, and i will only change the classes or sub calsses
