Thanks to everyone that offered suggestions and help. Eventually, I deleted everything in the build directory and reran configure.sh from the ~/sources/reactos directory as per the web instructions and lo - problem solved. Only thing is - why did the original procedure suddenly fail? Is it necessary (or just a good idea) to re-initialize the build output directory each time? Would be nice to know.

I had this same problem and solved it by going into the file drivers\usb\usbdebug.h and adding this as the fourth line.

#define BUGCODE_USB_DRIVER (0xFE)

This may have come from where I had seen this line in a previous review or post.
Unfortunately, I cannot remember exactly now.

The error may not occur for some that retained the pre-compiled header with this already included, but I am no expert here.
Maybe this will help someone else who has this same problem.

Edit: Due to recent additions in the USB programs directory, I had to move the line above into drivers\usb\usbport.h file.
I added it at line #46 based on surrounding defines and now I can compile again.
