Upon further consideration, I’m pretty sure USB 2.0 never touches the Thunderbolt controllers. And so there don’t appear to be any shenanigans required for USB on Titan Ridge in peripheral mode.Īs far as I know, You can only use both USB ports of Alpine Ridge when it is in host mode which has both Thunderbolt ports as downstream. So what makes the JHL7440 special is that it can accept USB-C with DisplayPort alt mode as input through a Thunderbolt port. The Blackmagic eGPU is similar to my dock but it uses a JHL7540 so maybe all Titan Ridge chips have the separate USB output.

I have tested a USB 2.0 mouse and a USB 3.x flash drive. The USB output of the Titan Ridge is just for USB (port 2 for USB 2.0 and port 4 for USB 3.x). The downstream Thunderbolt port can be used for USB (port 1 for USB 2.0, port 3 for USB 3.x), DisplayPort, or Thunderbolt. The Titan Ridge is different than Alpine Ridge because it has a USB output that is separate from the two Thunderbolt outputs.

Yes, the driver for the USB 2.0 port on my Titan Ridge dock is AppleUSBXHCITR. The audio codec probably needs a couple S2I connections to the T2 chip. There’s also the JHL7540, a pair of TI CD3217B or similar USB PD/Type-C port controllers, and possibly a Cirrus Logic CS42L83 audio codec on the card, but you can’t make out any of the part numbers. I did spy a pair of TI TUSB1002A USB 3.2 10 Gbit/s dual-channel linear redrivers on the I/O card, which would be for the USB 3.0 signals routed from the PCH to the USB Type-A ports via the proprietary portion of the I/O card connector. Which is one too many for the PCH, so there must be a hub or additional USB 2.0 EHCI somewhere to make that work. So now you have me thinking, the C621 PCH only provides 14 USB 2.0 ports, and by my count:Ģ for the Thunderbolt 3 ports on the top of the caseĢ for the Thunderbolt 3 ports on the Apple I/O cardĢ for the USB 3.0 Type-A ports on the Apple I/O cardĤ for MPX slot 1 (up to 4 Thunderbolt 3 ports)Ĥ for MPX slot 2 (up to 4 Thunderbolt 3 ports)
