5 Gbit/s USB-3.0 SuperSpeed with Fairphone 3+

Does the Fairphone 3+ support 5 Gbit/s USB-3.0 SuperSpeed?

I’m currently running /e/ eOS IMG-e-0.14-q-2021012698290-dev-FP3.zip.
So this may play a role in this.

I’ve done several tests. But my Fairphone 3+ always shows up via the logical USB-2.0 hub and with a speed of 480 (tested with Linux-5.10).

# Fairphone 3+
$ cat /sys/bus/usb/devices/2-1.1/speed                                                
480

# USB-3.0 mass storage, connected to the same port
$ cat /sys/bus/usb/devices/4-1.2/speed                                                
5000
# So "2" is the logical USB-2.0 hub and "4" is the logical USB-3.0 hub.

 

Same results with:

  • My computer (USB 3.1 PCIe card) via the original Fairphone USB-A to USB-C cable
  • My notebook
    • via the original Fairphone USB-A to USB-C cable
    • via an USB-C to USB-C cable

The USB 3 pins are physically not there in the USB-C connector: you can look into it and see that it is missing some pins.

Sounds like a good idea for a future module upgrade.

Upgrading the module to add pins wouldn’t do anything :thinking:

@amoun Please elaborate. I’m quite tech savvy, but it appears you know more then I do.

The pins not only need to be connected to something but that something ( USB 3 protocol) has to be worked into the core module by design. I image if it was available then the pins would be there to use it.

That was my guess as well. The connector to the core module has 48 pins (compared to 18 + ground on the FP2 which has mostly the same features in the bottom module), but that seems to be because it’s the same connector used on other FP3 modules as well.

Maybe I wasn’t expressing myself well enough. I was thinking of a new bottom-module that is USB-4 compatible. Similar to the new (FP3+) camera module: they can be swapperd without hardly any effort. Or similar to plugging in a USB-3 PCIe device into the motherboard of a desktop pc. Does that make sense?

Given my response to the US3 idea ?

I think the bottom module is just a connection point all the chips and software, the working parts’ are on the core module.
