Subject: Proposal: change keycode for scancode e0 32 from 150 to 172

Hi all,

As some of you might know from my earlier post/thread about atkbd and softraw, 
I'm currently working on getting keyboards with internet/easy access keys to 
work painlessly / plug and play.

In order to be able to better test / develop this I've bought 2 cheap such 
keyboards today, one ps2 and one both usb and ps2 capable.

When comparing usb vs ps2 / testing the keycodes generated for the easy access
keys on my trust (microsoft compatible) keyboard. I noticed the homepage key 
sends keycode 150 with ps2 and 172 with USB, or for those who don't know the 
keycodes by head with ps2 it sends KEY_WWW and with usb it sends KEY_HOMEPAGE

I personally believe that the usb behaviour is correct and that the ps/2 code 
should be modified to match for consistency. The ps/2 scancode to keycode 
mapping is set up to handle easy access / internet keys for microsoft 
compatible keyboards. So what is the right code to send here, tricky, see:

http://www.keyboardco.com/keyboard_images/microsoft_ergonomic_keyboard_4000_black_usb_large.jpg

The logo on the key is a homepage logo, the text below is www/homepage. So what 
to send? I believe that for consistency with the usb codes send it should be 
KEY_HOMEPAGE, but thats based on a sample of 1 usb keyboard. Input on what 
other usb keyboards send for the key with the homepage iocn is very much welcome.

Regards,

Hans
