New! RE: PLz Help

Why not just use a cable between the two USB [thingies]?

If one is master and one is slave, and the master has the correct software, then a cable should be enough, unless you need a repeater because of large distances.

If the two are masters, then they are not intended to talk with each other. Same of the two are devices.

So, instead of settling for the non-descriptive subject "PLz Help", I think you will have to sit down and actually write down exactly what problem you have, and why you need a solution for the problem. Yes, I know. Tough work to have to describe your problem...

"i don't have any idea about this"

You really should start with something simpler, then!

Here's a reading list: http://www.keil.com/books

New! make 2 USB Communicate with each other

What do you actually mean by that?!

Remember that the 'U' in "USB" stands for "Universal" - so saying "2 USB" is almost completely meaningless!
They could be just about anything - modems, cameras, speakers, storage, JTAG debuggers, mice, keyboards, etc, etc, etc...

You need to state what two USB "things" you need to "communicate".
You probably also need to state in what way(s) you want them to "communicate".

The first step in any project is to clearly define exactly what you are trying to achieve!

New! RE: make 2 USB Communicate with each other

Stage One : I want to transfer a txt file form one USB flash Drive [ Pen drive] that will act as Host to the other USB flash Drive which will act as Client.

for that i want to know which MC have more than one USB support I/O port so that i can directly connected the USB to the port and get the output from the other one.

New! USB flash Drive [ Pen drive] that will act as Host

No, it does not work like that!

A USB flash Drive [ Pen drive] is a Device (or "Slave") and can never be a Host!

To do what you describe would require something with two USB Host ports.

Was there a reason for you to wait with bringing us this information? In my first post, I did request that you took your time and explained exactly what you wanted to do.

Connecting to two devices, and drag information from one and push it to the other do require two host controllers. The parametric search available on this web site allows you to check what ARM chips that has at least two USB host controllers or USB OTG (On-the-go) controllers.

But the big issue here is your knowledge level. The project is not trivial. If you do have the required knowledge to manage this kind of project, you would have the required knowledge to be able to select a suitable processor on your own.

I very strongly recommend that you select a different project if this is a school assignment. And if you just want a copier - buy one!
