On my Macbook Pro, I routinely use two keyboards:
#1 is Apple Keyboard (A1243) with International English layout
#2 is Apple Keyboard (A1048) with French layout.
I already have set up a keyboard shortcut to switch language, but I'm looking for a way to automatically switch the language as soon as I begin typing on a given keyboard.
Does the OS even know which layout each keyboard has?
Apple Pro Keyboard: Product ID: 0x020c Vendor ID: 0x05ac (Apple Inc.) Version: 4.10 Speed: Up to 12 Mb/sec Manufacturer: Mitsumi Electric Location ID: 0x26443000 / 11 Current Available (mA): 250 Current Required (mA): 50 Apple Keyboard: Product ID: 0x0221 Vendor ID: 0x05ac (Apple Inc.) Version: 0.69 Speed: Up to 1.5 Mb/sec Manufacturer: Apple, Inc Location ID: 0x24120000 / 4 Current Available (mA): 100 Current Required (mA): 20
Do keyboards even have a language, or just different stickers on the keys ?
I could maybe take advantage of the fact that I'm using two different models. I'm open to a low level solution (something like listening to keyboard inputs and switch language accordingly, if you can find the origin on the USB bus of a keystroke, but it would be a programming question for StackOverflow I guess).
