need help with picbasic sample programs. They wont compile.

[FriendOfGhost]

dear friends,

I downloaded picbasic 3.0.5 from sonsivri and everything is fine. except I cannot run usb samples. there's a folder "C:\PBP3\EXAMPLES\LABXUSB-18F4550" and under that folder there's a "USBMOUSE.pbp" file. it loads but consistently I get "symbol not previously defined (usbdeviceinit)" error. I remarked every code and same error raises even with the single "USBInit" statement. I googled so many documents and I guess its about include files. but there's no include file in original sample. also this picpasic pro is clen installation on clean windows xp.

can you help me please ? why original installation samples wont work. what should I change in order to compile this simple program ? it doesnt need to run, I just need to compile it..

Define OSC 20
    USBInit
aaa:
       USBService                    ' Must service USB regularly
'       USBOut 1, buffer, 4, endgame  ' Send buffer to endpoint 1
   Goto aaa      ' Do it forever
 
  End

The best thing to do is search for all the readme's in the directories because there scattered all through them
and of course read them  and don't forget the forum at PBP http://www.picbasic.co.uk/forum/forum.php lot's to learn from there
