Usb C hub not working on MacOS Ventura

Sharing my own solution that I discovered today. Short Version: Check your Allow accessories to connect option. You can find this in System Settings > Privacy & Security > Scroll down and you'll find it above FireVault. I changed this value to Automatically When Unlocked and it solved everything.

Long Version: I have a USB C display out to a monitor that has USB A ports. Display works without issues after updating to Ventura, but the USB A ports stopped reading devices. In addition to this, I noticed my external HDD wasn't direct connecting via USB C either. After several unplug/replug attempts, I noticed a prompt would pop up but disappear in less than a second. Had to record my screen and playback frame by frame to read it. It was asking me to allow the accessory to connect. I changed the value in the settings described above and solved all USB C issues including the HDD and hub! The strange thing is that the Allow prompt never showed up when I tried using the USB hub. My guess is that this prompt is not showing up for most devices and leaving Ventura users in the dark.

to me, that would indicate that you have something installed in your normal user account that became an issue after upgrading your macOS.

i'm thinking you should download and run the free version of EtreCheck so we can see if you have some software installed that is causing your issue. make sure you give "full disk access" to etrecheck. Learn how to use it by reading Using EtreCheck. if you need help interpreting the report, you can see how to post the report here by reading How to use the Add Text Feature When Posting Large Amounts of Text, i.e. an Etrecheck Report. and it automatically obscures sensitive things (like serial numbers) so you don't have to worry about sharing the report here.

That means there's some 3rd party software that is interfering with the hub's performance.

Download and run Etrecheck.  Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

Copy the report

and use the Additional Text button to paste the report in your reply.

Then we can evaluate the report to see if we can determine the cause of the problem.

Following up: I got through to Apple Support via phone, and the tech had me perform an SMC reset. This fixed it.

This is the procedure I performed: Reset the SMC of your Mac - Apple Support

Hope this helps you!

Finally got my setup working. 13.3 improved things, but I still wasn't getting reliable connections without fiddling. Turns out my self-powered USB Hub was not working well enough – replacing it with a better model worked for me. My old model had individual power switches per USB plug. The new one does not. Old model had lower voltage output than the new model as well – it's possible some of the USB connections weren't getting enough power.

The newer hub I'm using: https://www.amazon.com/dp/B0BHLMKCL4

The older hub I just tossed was similar to this model (same brand and general feature set, but the exact model I had is discontinued): https://www.amazon.com/dp/B0B7WVY8QF

My old hub was working fine for me on macOS 12 though, so there may be a software component to the failure. That said, I also plugged more devices into the hub after updating to macOS 13, so who knows.

TLDR: Run the USB for your keyboard & mouse directly to your Mac vs. through the USB-C hub.

This is a follow-up to a previous post.

Personal System: 13-inch, Macbook Pro, M1, 2020, Ventura 13.0.1

Work System: 16-inch, Macbook Pro, Intel, 2019, Monterey 12.6

USB-C Hub: QGeeM, Dual Monitor, D6908-LX4

KVM: TESmart 2x1 HDMI

After setting the Privacy & Security > Allow accessories to connect > Always preference, I was still experiencing issues where my keyboard would not awaken my sleeping, closed-lid MBP running Ventura.

Today, I ran through some tests and determined that my QGeeM USB-C hub was not able to wake up my closed-lid 13" MBP M1 (2020). The Mac was refusing to recognize the USB keyboard & mouse. I also have my USB hub connected to a KVM so that I can switch between work & home MBPs.

In any case, as part of my testing I plugged my keyboard's wireless fob into my personal M1 Mac directly and it was able to awaken the closed-lid Mac. Since I have to share this across the KVM to my work Mac, I decided to plug the KVM's USB input directly to my personal Mac instead of running it through the QGeeM dual-monitor USB-C dock.

Now this works 100% of the time.

A few side notes:

1. Don't use the keyboard & mouse USB connections on the KVM as they will not transmit device information to the Mac
2. Plug a USB hub into the USB 2.0 connection & plug the mouse & keyboard into the hub; then you can use your device drivers / software (like Logi Options)
3. My KVM is a single monitor switch, so I use a remote controlled HDMI switcher to manage my 2nd screen
4. The QGeeM hub uses DisplayLink Manager software to run the second screen. This is needed on the 13-inch M1 2020 since it can only power one monitor.

I couldn't bear it and called support. Safe-Mode and all the resets etc. didn't work, but reinstalling Ventura using Recovery actually did...

I am not sure whether it'll break again or not, but currently it works as expected now.

I still wish we had a way to undo the last update (at least and especially a major one), but at least my issue is currently solved. Both the screen (USB-C) and the WD19S Dell Docking Station work now.

I update my MBP 16 M1 to the latest version of Ventura and it looks like all of the issues that I was having went away.

Today is my second day with that version and hopefully will not have to deal with that problem again.

macOS 13.1 (22C65)

I am having the same issue ever since I updated Ventura. My solution every morning is to try to unplug and replug all of the TS4, some times it is not working, and the best solution is to restart my MBP 16 M1.

I believe if you download the Monterey from Apple's website and create the installer on a USB you can downgrade to that.

For the questions, I am using a CalDigit TS4 docking station with its own power. It is not the dock since I get the same problem with the Anker and an off-brand as well.

Update Fixed mine: I removed power (PD passthrough) from the Anker Hub, then disconnected from the Mac, then reconnected the Hub to the Mac, with no Power (PD passthrough) the Mac recognised it, and then reconnected the Apple USB-C Power Adapter to the Anker Hub. All is working again. Tested plugging in and out all good.

It worked for me after changing a new configuration in Privacy and Security "Allow accessories to connect". I changed it to "Automatically When Unlocked" and couple of restarts. Hope it helps.

Greeting Dennis

I am having a similar issue. Here is my setup:

• 13-inch MBP M1 2020 / 16GB
• Ventura 13.0.1
• QGeeM USB-C, Dual Monitor, Powered Hub
• Single USB-C connector to QGeeM hub for USB, Power, 2 Monitors
• Wireless Microsoft keyboard with USB dongle
• Wireless Logitech trackball with USB dongle
• Laptop is is kept closed on the desktop

Prior to the Ventura upgrade, I was able to wake the MBP with keyboard or mouse activity. After the upgrade, I must power cycle the USB hub or open the clamshell (which has limited space for opening). This is required after falling asleep — multiple times per day. I've taken to using the "KeepingYouAwake" utility to keep the mac awake for 8 hours so I don't have to power cycle so often.

I'm experimenting with other solutions. Just today I set the System Settings > Privacy & Security > Allow accessories to connect > Always ...

This did not solve it completely, but I was able to awaken the MBP with my Logi Trackball using the Bluetooth connection (it has both USB & BT). That was enough to get me to the login screen and then the USB keyboard was operational.

Previous attempts at using the Bluetooth option were successful in awakening the MBP but did not allow the USB keyboard to enter the login credentials.

Well, I think I figured it out.

Out of curiousity I ordered and received a Thunderbolt 3 (THREE) cable (0.8 M original Apple White) and it is working for me for 1 hour now flawlessly. I am using a Studio Display on an Intel Macbook Pro as an external screen/camera and hub.

With original Thunderbolt 4 (FOUR) cable nothing but trouble from the start. Fingers crossed.... and mayby worth a try for the other Mac users.

Very interesting. This way worked for me:

Setting to always ask.

Plugin hub and check to use hub.

Reboot

Setting to always allow.
