Ducky Shine II and Linux
« on: Tue, 27 November 2012, 19:03:43 »
So I finally joined the mechanical keyboard community with a Ducky Shine II and am loving it so far.  The only thing I noticed is that the NumLock LED is on when it should be, however the ScrollLock and the CapLock never light up though they do do what they're supposed to.  Anyone know what's up?  The LEDs work fine in Windows 7 BTW...

I use a Ducky Shine (version 1) on a Mac, and Num Lock does not light up (Macs do not have that facility).

Maybe Linux is just not recognising the key code when you press those keys.  Although Caps Lock is suspicious.

"Because keyboards are accessories to PC makers, they focus on minimizing the manufacturing costs. But that’s incorrect. It’s in HHKB’s slogan, but when America’s cowboys were in the middle of a trip and their horse died, they would leave the horse there. But even if they were in the middle of a desert, they would take their saddle with them. The horse was a consumable good, but the saddle was an interface that their bodies had gotten used to. In the same vein, PCs are consumable goods, while keyboards are important interfaces." - Eiiti Wada

It probably has to do with the multiple HID profiles aliasing - there are N number of virtual keyboards to allow registering for N-key roll over.

Its a nasty steaming hack, but then you'd be limited to USB's ~64 key rollover limit...IIRC.

Somehow the numlock indicator was on the 1st keyboard, the others elsewhere...linux has no idea which keyboards are real.
(KB should probably just merge all the LEDs in software)

This is another reason why PS/2 is still superior -  The USB HID profiles have a great many limits, this isn't even the worst - have you ever wondered what the USB  (UHCI) software stack does to latency?

It destroys it.

Thanks for the replies!  I wish there were more PS/2 support in keyboards, but they all seem to be going the way of USB...  just curious, would one suffer these hacks if it was a PS/2 keyboard with a USB adapter?
