Hi!

When you have installed a bootloader (4550.hex) in your pic and then you have programmed with it and Microchip USB HID Bootloader v.2.2 an application to it, how can you then afterwards invoke the bootloader ?

Is it by pulling down RB4?

I have RC5 pulled up to tell the hw that a bootloader is in use "here. Can't remember where from I got that info. Is that correct?

If you can, please help!
