Re: windows noob needs pointers to writing a device driver

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

the extra key's scan codes in a sun keyboard are not handled by the keyboard
stack, they are handled by windows input subsystem itself (the raw input
thread (RIT)). if it is a ps2 device, the scan codes bubble up to the RIT.
if it is a usb device, they are probably lost at the HID mapper layer
(kbdhid.sys) b/c the parser does not know about the usage -> scan code
mapping for those keys (but it could, this is off the top of my head).
Technically you could attempt to add value here, but that would be very
difficult given how kbdhid reports packets.

If the device is neither ps2 or usb, you have a lot more work to do b/c you
need to interface w/the hw itself.

USB keyboards do not need drivers. Windows supplies one automatically.

What about a Sun Type 6 keyboard? I can't seem to the the extra function
keys (cut/paste/front/again ... etc) to work.

I'll have a look at the DDK, thanks.
