I am using microsontroller PIC 18F2450.

The issue is: when trying to compile and assemble the source file USBDemo.PBP from Steeve I get the following error messages:

ERROR: Macro USBINIT? not found in macro file.
ERROR: Macro USBSERVICE? not found in macro file.
ERROR: Macro USBIN?CBBL not found in macro file.
ERROR: Macro USBOUT?CBBL not found in macro file.

I did make any change to the original files as posted on this forum.

Could any one be of help to me?

My file locations are as follows:
MPASM D:\Program Files\PBP\MPASM
PBP D:\Program Files\PBP

When loading the USBDemo.HEX file in my microcontroller (18F4450 and 18F2450) it works fine with the PC application from Steeve.

In advance many thanks for your help.

I have the same problem as above but I am using a 18F2550. What am I missing or where did I go wrong?

I am configured for a 18F2550 but the USBDEMO.MAC file is overwritten without the needed macros each time I try to compile.
