Re: [Trisquel-users] Apple keyboard firmware hack demonstrated

[dguthrie]

Apple keyboards, even the internal ones, are USB, so the logic is stored in  
flash memory on the actual keyboard. Keyboards on most other laptops connect  
with LPC.
USB has other problems, because it is designed for dynamically plugging and  
unplugging peripherals. For example some OSs download drivers, and partition  
tables have to be refreshed, for instance, so there is much greater attack  
surface than other connection protocols like LPC.
