This is great but why cannot you do it? I think it is cheaper, no mechanics (that can fail), easier to build and only you have to disable it by software. Even if user pushes the button, nothing will...
Yes, that explains everything. Unfortunately, I can't use the HSERIN/HSEROUT ports available in the 18F4550 because they are already taken doing the hardware communication. Increasing the baud rate...
The PIC ports with HSEROUT and HSERIN are already taken. Using a baud rate of 9600 instead of 19200 made a difference. It is now working fine. The USB Darrel's interrupt takes micro seconds to...

Since this question has come up again, I thought I'd throw this module out to the masses. It is something I worked on a while back, with DT's help. Amid life's other priorities, it got put on the shelf to collect dust.
The basic idea is that by adding the module as an INCLUDE and inserting a couple of commands inside your code, you can have the PIC send timing data to your PC via the hardware serial port. It's made for 18F PICs (although some 16Fs may work too). You also need a timer that is not being used for anything else.
1) Instructions are included, as well as a small example.
2) It worked well for me, and as I recall, DT in testing.
3) Use it however you want.
4) I won't be able to offer much support, but figure there are enough knowledgeable folks around here that can help those who need it.
