That USB-C guy at Google
Benson LeungSep 12, 2023

Two big USB-C news stories today!

Intel has announced Thunderbolt 5, which is their high-end implementation of USB4 80Gbps and the advanced 120G/40G asymmetric mode.

Apple has finally made the jump to USB-C on iPhone, iPhone Pro, and many of their varied lightning accessories too.

Very positive news all around!

@ant_pruitt Thank you so much for hosting Stacey's Book Club today on Project Hail Mary! It as a lot of fun to nerd over the book with you all in Discord. (I'm LaughingMan11 in the Discord chat, btw)!

chrome://system/#typec_connector_class will display information about any USB Type-C partner and cable you attach. The output is only lightly processed from the raw objects we get from the devices themselves, but the info is there!

All of the above are notifications that occur to inform the user when something goes wrong, but what if you just want more info on the devices or cables you have plugged in? We built a diagnostic utility into M99+.

We also detect conditions where the device is functional, but limited in speed because of the choice of cable (ie, cable's only 20 Gbps rated while the device is rated for 40 Gbps).

Our USB4 Chromebooks also support Thunderbolt 3 peripherals, and just like USB4, the speed and capability of the cable matters. Once again, we've built a notification to warn the user when a combination of cable and device don't mix.

Many of our latest Chromebooks support USB4. USB4 is an advanced mode where the speed and limitations of the cable also matters, and we've built notifications to help the user when connecting to USB4 devices with a cable that can't support the new mode.

All USB-C cables, even those without logos, identify themselves to the computer precisely (using USB PD), and my team reads that info now, and we eliminate a silent failure when the user uses a USB 2.0-only cable with a DP Dock or Monitor.

Good quality cables certified by USB-IF may have these official logos. These help distinguish cables visually. Logos are only half the solution though: How is a user supposed to know which logo to look for to support DisplayPort?
