Anyone can help me?
I would like interface a pic (16f84 or 16f876 or anyone..) with a usb.. If possible, How can I do?

Yes if a small PIC like the 16F84 can interface to USB using a FTDI chip. The chip is simple to use and cheap.
Although the 16F84 and 16F876 can't supply the bandwidth, you will have no problem with the FTDI chip, it can do 1 Mega BYTE /Second (8 mb/s)
I have used it with a PIC18F452 running at 40MHz and was able to do some serious work at 250KBytes/Second (2.5mb/s)

Ok,but were I can find this chip? His name is only FTDI?
And after,wat i have to do for use USB?
I have cmpiler version 3.048 And I haven't the header for USB..

But I haven't the header of usb..
My version compiler is 3.048

Everything is at the FDTI site. Check the "Sales Network" you will find links to all the places in the world that sell the chip.
Aslo at the site there are links to demo software and evaulation kits.
If ytou are serious about doing this, spend $75 on and eval. kit from DLP Designs and you will get enough to understand everything you need to know to use the FTDI chipc and how to talk/listen to your device from a regular PC (Windows or Mac)

I have just used a FTDI part to quick and dirtily upgrade a RS232 based PIC project to USB. Works superbly. You can even edit the .ini file and have your products name in the hardware list under windows!

OK.. but what kind of FTDI have you use?
And, how can I communicate from pc to the devece?
After, I can use the usb at the same how rs232..?

yea, but you get a nuisance WinXP certificate compromised

So,can you use your own product descriptor in that case or not?

With the source code of the driver, you can put any 'name' to it you want. However the USB descriptor, will remain as FTDI's. Neatly though, you can attach an EEPROM to some of their chips, which contains a different descriptor ID, and then provided you have paid the license fee for an ID, have your own ID and description. :-)

Not correct FTDI issue blocks of ID's at no charge. |

Only in their product ID block.
They will custom make chips with different vendor codes, and still with programmable product ID's if you want quantity. If you want a unique vendor code, then you have to pay for this. Otherwise the manufacturing 'source' of the chip, is allways identified as FTDI.
It depends on how unique you want the product to be.

But if you use FTDI VID and the PID that they give you. You will be able to get around the win XP auto driver install problem.
Also see my note related to CCS ICD-U40 that also used the FTDI chip.
