usb keypad

Well, there is missing USBInit in the code.
This is happen when my beer is over.
Now Windows say: "There is unknown usb device"
What must to be changed in the descriptor?

I cheat when it comes to simple keypad applications. I just take the PCB from an old USB keyboard and hack the 2 connectors . The ones I have used so far use 2 connectors, then I map the connectors into a table.

The nice thing is that the USB communication is already complete and Windows recognizes yor device without problem. You can connect more than 1 identical keyboards in Windows XP.

There are several examples on google to hack a USB keyboard.

Thanks Daemon
The task I'm doing is litlle more complicated.
I need to send serial commands to other devices (HDMI Switch, etc.) and Keyboard events simultaneously from
this board. I also image a situation to receive commands from something.
If I use standart keypad I must to design serial-to-command-to-matrix decoder and vs.
By the way the board is still not recognized by Windows as HID. I check report descriptor twice,
the device descriptor seems ok but pic freezing by usbout.
May be some configs are wrong? I dont have any.

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.
