#39c3 was amazing again! Met lots of old and new friends again despite having to build slides and unfortunately missed a few people I wanted to talk to as usual. Didn’t get much sleep and looking forward to catch up on that now.
Can’t wait for next year!

The plan: I’m gonna finish my slides on day 1 long before the evening, this is gonna be easy and there’s plenty of time.
Reality: spent the past hours talking to people and not even starting with the title slide 😅

You may have heard of eUSB, the low-voltage cousin to the venerable USB 2.0 from 25 years ago. It's used on SoCs made on small process nodes that can't support standard USB 2.0 voltage levels. Turns out, it recently got an upgrade called eUSB2V2 (yes, really). It supports asymmetric operation (which is a first for USB) at up to 4.8Gbit/s and is aimed at connecting high-resolution webcams in laptops.
