What is interesting is that "low security" of the flashing process won't hurt their sales - I would expect the opposite to happen. Free publicity exactly where your customers are. Good for you, Coolermaster!

#12This was very educational. I find it equally hilarious, scary and wonderful that it's now cost-effective to build a keyboard whose brain is a 72 MHz ARM Cortex-M3 with 127 KB of program space. Of course the manufacturer also proudly tells you this, that the keyboard is powered by an ARM. It's also fun that the firmware of the keyboard is protected (partly by the old-faithful XOR trick, even!) against IP theft. Too ba…

#13I like skimming articles. Got to page 2 and lost interest. If it was all in one page, I may have found something of interest further down and gone back up to read the whole thing.

#15Earlier quoted context omitted.
It's probably more than powerful enough to emulate a C64... where the computer is literally inside the keyboard. But with all the concern over malicious USB devices, I'll take a dumb and simple PS/2 keyboard with a mask-programmed 8048 over anything "smarter". Otherwise, his idea of requiring a special key combination to enter firmware update mode is also good - something like "unplug, then hold down X while plugging…
Personally, I think we need more open source day-to-day peripherals like this: keyboards, USB hubs, card readers, everything. It all needs to be replaced with open, inspectable, blob-less, user-upgradable alternatives.

Another view is that microchips are made of what is essentially sand.
