How to work with USBMOUSE ?

[iugmoh]

Hi all, thanks for all members in our favorite forum

I build the USBDEMO and I can play with PIC and VB6 which add new interface in our knowledge.

now I want to update my code so I can control of mouse cursor , I saw that there are an example usbmouse but not working with PIC18F4455.
so I need help in this problem
Here is my code which nothing happened to mouse cursor:

' Pic Configuration

Oky , I have got it work now
I discover that I must add MOUSDESC.ASM file and change USBDESC.asm file to include previous file. But I have another question how I can combine usbdemo with usbmouse so I can control mouse curser and control pins from VB6
here is my code:

i NEVER EVER messed with the mouseDemo...

BUT...You need to know which PID/VID it use.. if any (USBDemo use the default one generated with EasyHID).. unless it will never work.

Q: Sir... how may i know the VID/PID?
A: USBDeview is a nice & free Utility ( http://www.nirsoft.net/utils/usb_devices_view.html )

thanks mister alot and I don't know how to thank you.
I now can plug in using vb6 but no data recieved or nothing transmited to PIC I don't now why

Hi all, I want to ask how to implement right click button and left click button and scroll click button for usbmouse

[iugmoh]

Oky after no replying from anyone I try by myself to make this thing, and after many searching and trial and error, I achive it and done it.
this site help me in our work
