Solo2 not working with Apple silicon?

[Tamerz]

Hello. I have a Solo2 USB-C device. When I plug it in to a MacBook Pro with M1 chip, it is not detected. Not even the LED light on it turns on. solo2 ls doesn't show anything.

When I plug the same device into either a Windows machine, or an Intel MacBook Pro, it works fine.

Anyone else run into this issue?

@Tamerz Can you reverse it 180° and try again, or try different port? I would be afraid it's hardware failure on the Mac side...

[Tamerz]

It is definitely not the port. It doesn't work on any of the three USB-C ports, but other accessories have zero problems. I just tested all of them with a USB drive and a Thunderbolt Ethernet dongle and all worked perfectly.

$ sudo dmesg | grep IOPortTransportStateUSB shows a flood of events when the device gets plugged in:

I just tested it in an M2 MacBook Pro and it lights up fine. I'll try another M1 device, and if that works then I know it is something specific to my machine.

[Tamerz]

Works fine on another M1 machine. Closing this as something wrong with my machine.
