usb keypad

[Demon]

I'm stuck to using my cell phone so I can't do serious debugging.

Do you issue that USB SERVICE command or whatever it is called to keep your connection alive?

Sorry, wished I could be of more help.

OK its done. The problem was in the serial bootloader.
And for ICSP the reset cap C3 must be far below 100nF - 10nF or lower.
I will post code soon as is ready. Then will make fun with the serial bootloader. I love UARTs!
Thank you Demon, you break myself talking hardly.
Cheers to all of you.
