I am using the 18F4550 pic, Picbasic Pro 2.50 and MicroCode Studio Plus 3.0.0.5

When I compile it gives the following errors.

Error[118] c:\progr~1\mecani~1\mcs\usbdemo.asm 87 : Overwriting previous address contents (0000)

Are these errors anything to be concerned with?

Also out of interest, I am using a 4Mhz Resonator but in the code it is: DEFINE OSC 48

What is that about?

However, I seem to be making progress because when I plug it into the USB of the computer. I get the message found new hardware "USB Demo" but then it gives a message There were problems ........ etc etc.

The VB Application is not picking it up yet.
