[Solved] Satechi Thunderbolt 3 Hub Strange Disconnect Behavior
I've encountered some strange disconnect behavior with my Satechi thunderbolt 3 hub which connects my external keyboard and mouse to my setup.
Some info on my whole setup.
- 2019 MBP 15 in, Running OS Mojave 10.14.6
- Razer X Core with Radeon Vega 56
- Satechi hub
- Connects to right port on MBP
- 2 USB connections from Razer Hunter Elite Keyboard
- 1 USB connection from Razer Naga Trinity Mouse
So first, I've had no issues with this setup for about a month. But now I'm seeing this weird issue.
Here's the problem. When I turn on my Mac, everything looks good, my keyboard and mouse are functioning, but when I
enter my password and login the lights on my keyboard and mouse turn off probably halfway through the desktop loading time. Once I'm at my desktop, the lights are off, and they no longer function. My eGPU still works fine as usual. I just become limited to only using my Mac keyboard and trackpad. So the strangeness comes in here. After about 40 minutes-1 hour of having my setup on, my keyboard and mouse just magically light up and resume functioning as usual! This has happened 2 days in a row. Another thing to note; if I put the Mac to sleep, and come back after the keyboard and mouse working again, they still work when the Mac wakes up from sleep. This odd behavior seems to be triggered when I fully power off the Mac, and turn it back on.
To me this behavior is strange because the keyboard and mouse will consistently be functional at the login screen, and then consistently stop functioning as I login to my desktop. And then I change nothing in my 40min-1 hour of being logged in for the keyboard and mouse to start functioning again.
Not sure what's going on. Any ideas?
@auro Time to try a different hub?
I think the Satechi is a USB-C hub with one Thunderbolt pass-thru connector. It doesn't report itself as a Thunderbolt device, correct?
@joevt Yeah, you're right. Here's the link to the adapter.
@auro I was looking at one of the adapters that had two USB-C male connectors - one for the USB-C hub and the other for Thunderbolt pass thru.
The second one doesn't mention 40 Gbps capability, so maybe it doesn't support Thunderbolt pass thru?
The one you linked is just a USB-C hub - there's no Thunderbolt about it. Anyway, for a USB-C hub, the behavior you describe is strange. I would try a different USB-C hub. If it's still under warranty then get a replacement.
Does the problem exist while USB-C charger is connected to the hub?
The issue wasn't the adapter. I bought another adapter and the setup experienced the same behavior. The issue turned out to be the logic board on the Mac. I went into Apple and they sent it out to get fixed. Came back in 2 days! Working great now.
