Usb C hub not working on MacOS Ventura

Update, I've found a way to get USB devices plugged into a hub to connect to my Mac without rebooting:

1. Unplug computer from USB devices
2. Put computer to sleep
3. Plug in USB devices
4. Wake up computer
5. Wait 30 seconds

Faster than what I was doing before. Still clearly quite busted.

Short update, what helped in my case:

1. Disconnect usb hub.
2. Disconnect power supply.
3. Disconnect second screen from hub.
4. Connect screen directly to USB-C.
5. When works, reconnect screen to hub.
6. Connect hub to macbook.
7. Plug in power supply.

Maybe it will be helpful for some of readers.

I just fixed this issue for my 2021 M1 16" MacBook Pro.

Mac OS Ventura requires you grant access to USB C accessories. I didn't receive a popup prompting me to grant access to my dock, so it didn't work. My steps to fix:

System Settings > Privacy & Security > Allow accessories to connect > Change to "Always"

Choose the security setting you're comfortable with, of course. As soon as I changed this setting, my dock, monitors, external camera, etc came to life.

Oddly enough my USB-C hub works with 13.1... sometimes. After closing all programs and rebooting it seems as if the USB-C Hub (Dell WD19S) is recognized and delivers LAN, Power and Keyboard properly (HDMI was sketchy before Ventura, too).

However: after sleep-mode it seems to pick up the hub, but to drop it a couple of seconds later and after that the hub does not even work with another M1 Max laptop, that is still on 12.x MacOS. Unplugging and reattaching power from/to the hub makes it work under MacOS 12.x again and - if I had rebooted - Ventura, too.

It's really odd and I still dislike it, that Apple broke stuff, that used to work.

Sounds almost ridiculous, but perhaps worth a try! Even though USB-C can be plugged in either right-side-up or upside-down, you can try flipping the usb-c plug. In my case, I was using a usb-c extension cable from my usb-c hub to my 2018 Macbook Air (also, I do not have the "Allow accessories to connect" option at all). I flipped the female USB-C plug and now my usb-C hub works again!

This is where I found the solution that worked for me. I can confirm and vouch that the following worked for me. Wired usb keyboard and mouse stopped work… - Apple Community

I tried this and it did not fix the problem for me. I changed it back to "Automatically when unlocked".

However, what did "work" for me was the following:

1. After plugging in a Satechi USB-C Hub to my Mac, my external screen (connected via HDMI) stays blank
2. Go to System Settings -> Displays and see that the display is recognized by the system despite it being blank
3. I choose the external monitor, change the resolution from the default 1920x1200 to 1920x1080 (probably any other resolution would work as well)
4. Voilà! The display starts showing a picture
5. Turn the resolution back to the native resolution of 1920x1200
6. Repeat the procedure every time I connect the USB-C dongle

13.2 makes my devices more reliably connect, but it’s still not as good as 12.*.

unplugging/replugging my USB C device connection *while the device is unlocked* usually fixes connectivity issues for me now, which is a simpler workaround than I had before. This is still unacceptable performance but at least I no longer dread unplugging my laptop from its workstation.

I have a similar problem with an Anker 565. Worked fine under Monterrey and I believe under 13.1. But starting with 13.2, the usb ports stopped being powered: no more mouse, camera, headphone.

Apple support asked me to contact Anker support. I have now been in e-mail conversation with Anker for 2 weeks. They provided a firmware update but no instructions on how to install it. Firmware update to be done using a windows PC, which I have. Now, after 2 weeks, I still do no have working instructions. Their tool expects a .eeprom or .bin file and they provided a .fullrom file. They asked me to provide a video of where I get stuck, which I did. They also communicated to me that any Apple OS update may make the usb-c hub non-functional.

I have an M1 Pro MacBook Pro 16'.

Is there a usb-c hub or thunderbolt dock that does not suffer from such problems? Does a solution from Anker even exist? Or is there a solution from Apple?

can you try to boot in safe mode and check what happens?

Maybe there's a major issue with usb-c in ventura

I kept the ask for permission setting on and kept the dock plugged in, then unpowered the dock and powered it back on and got the pop up to approve. After approval, my dock started working again.

thats quite interesting. I have issues with my external display when I connect it with USB-C TB. (Mac OS Ventura + LG Ultrawide 49" - Apple Community

So it looks like Ventura has some major issues with USB-C devices, not only with specific device types.

I have to reboot to get a USB hub connected to my monitor (XDR display) to be recognized ever since upgrading to Ventura. Reboot works every time, but it's frustrating to have to reboot in order to connect to my hub.

Did you contact the manufacturers of the gaming monitor to see if it was compatible with Ventura?

You might have to get a separate, self powered hub for the drives and connect it directly to your MBP.

Just repeating what other people have said before, but I've had the exact same problem as federmoose ever since updating to Ventura. Under Monterey using HDMI monitor with a Satechi USB-C dock could sometimes require pulling out and re-inserting the HDMI cable, but on Ventura rebooting the computer with the USB-C dock plugged in is the only way to make it work.

Curiously the screen might show up in System Settings -> Displays but the screen would remain black, as if there was no signal.

Hi,

I'm not sure if that's relevant, but I have the same issue with a keyboard that disconnects over night. It's connected to thunderbolt/usb-c port.

I've found that the name of my keyboard was reported in /private/var/log/wifi.log log as a kind of wifi device. The log shows exact time when the device is being turned off, but does not say what is the reason. So I thought that maybe it has something to do with the thunderbolt network settings? Right now I've deactivated thunderbolt bridge from network settings and I'm going to check if that helps.

What's funny, the "other services" list in the network settings, where thunderbolt bridge was listed, was full of rp2040 entries. That's the chip name my keyboard is based on, but here they are listed as modems.

Maybe your USB hub is also somehow detected as a network modem or such?
