There are many types of USB slave configurations,
which one have you picked ??

Your device can never read a file from the PC, only the PC can write the file into your memory.

How your memory is configured is up to you.

No

You will need some sort of application running on the PC.
You will need to explain your project more fully, so I am able to understand what you want.

Thanks Don,

Now I'll connect it to the PC as slave, but I can't let the PC recognize my
board.
How can I let the PC know my device as memory to can read files direct from
the PC.
Is there a certain driver for the PC?

The USB port on the 4550 is a slave port, just like a USB Flash stick.

You can read a harddisk drive with a parallel port interface, or a SPI flash memory with the 4550.

Google has lots of examples, try searching "PIC18 harddrive" or "PIC18 MMC" or "PIC18 SD card".

good luck

Hello All,
I'm new to use USB or deal with memory like flash memory or Hard disk.
I need to read or write date from the flash memory on USB bus PIC18F4550.
Is there is any drive using C language to read and write data to the flash
memory?
OR any sites describe how to use?
