After Sonoma 14.4 update USB hub not working on MacBook

Same Issue here. I have a MacBook Pro M2 Pro and a Dell Monitor with a built in usb hub. Mac and Monitor connect via USB-C connector. Until Sonoma 14.4 it all worked fine. After 14.4, every time my Mac is put to "sleep" when it powers back up, the external monitor does come back up but any usb devices connected to the monitor hub get lost. Power cycling the monitor, or unplugging and plugging the monitor into the Mac does not help.

While my MacBook Pro does not see the devices, if I unplug and then plug the monitor into my MacBook Air running Ventura, all devices come online. Same with my windows laptop. Which leads me to believe that this is clearly a bug introduced in Ventura 14.4. Please fix.

I have two monitors connected directly to an M2 Max via thunderbolt. An LG Ergo 4K and a Dell U3219Q. This fix with setting "Ask for new accessories" worked for my LG monitor but not for the Dell. The Dell's dock still doesn't respond. Other devices not on 14.4 work fine.

Have tried a pram reset.

Or download the full 13GB update.

Apple is aware of the issue and a fix in the form of an upcoming 14.4.1 update is actually in the works.

I have the same issue with my MacBook Pro M2 Max 64GB RAM and monitor Dell U3219Q; none of the USB peripherals connected to the Monitor's USB hub work.

On the contrary, all peripherals work fine when I attach a Windows computer to the Dell Monitor. In addition, I check every USB peripheral by attaching them directly to the Mac, and of course, they are working.

I rebooted the Mac and detached the power plug from the Monitor, trying any configurations or sequences of rebooting as possible. Nothing is working since the update to Sonoma 14.4

Please, Apple, jump in and fix this issue soon.

In addition to the broken USB-C hub issue macOS 14.4 reportedly breaks Java settings and certain printer functionalities.

Specifically, printer drivers appear corrupted with the CUPS jobs missing. The bug affects HP printers.

I have a similar problem - everything on my M2 Pro worked fine on 14.4 but as soon as I restarted 14.4.1 my external monitor was no longer recognised, although peripherals still worked fine. I have traced the problem to a Selore plug-in hub which I have had to remove, and found a temporary workaround to give me my peripherals by using an old hub with a connecting lead (rather than direct plug-in) but I have found no way of getting the Mac to accept power this way. The monitor itself will now only connect if plugged in directly to one of the Mac's integral ports, using a USB-C to HDMI cable - leaving me with only one port on which I have to choose between peripherals and power! I also now have no way to connect to ethernet. Did no-one at Apple bother to actually test this 'fix'?

I have the same issue with the new Macbook Air 2024 M3 model. With my old MB Air with an older MacOS everything works perfect. Please fix ASAP Apple

I have the same issue. After the latest sonoma update, the usb hub of my Gigabyte M32u stopped working. Everything worked nice and smooth before, now I had to switch using external usb hub. Really dissapointing.

I have a similar problem. I have MacStudio and after updating to Sonoma 14.4, the hub in Dell u4919dw to which I connected the keyboard, mouse and sound card does not work. Interestingly, when I connect a mouse and keyboard to the rear USB-A ports, it doesn't work either. The sound card connected to the rear USB-A port works properly. If I want to connect a keyboard and mouse, I have to use an external hub connected to the USB-C port. Does anyone have an idea to solve this problem?

I'm encountering a similar issue and have tried troubleshooting it with two Mac models:

• MacBook Pro 14-inch, 2023, Apple M2 Pro and 32 GB RAM, running Sonoma 14.4.
• MacBook Pro 16-inch, 2023, Apple M2 Pro and 32 GB RAM, running Sonoma 14.4.

I'm utilizing a Dell P2720DC monitor, which typically functions flawlessly when connected to the Mac via USB-C Thunderbolt. However, ever since updating to Sonoma 14.4, the USB-HUB on the monitor appears to have ceased functioning properly, that is, no USB device connected works anymore.l

I tried the best answers from the community but nothing works for me.

I'm having the same issue on an M1 iMac with an external Seagate Ultra Slim portable hard drive I use as my Time Machine backup. Called in to support and they said there was nothing they could do, figured the hard drive might be fried. Yesterday, it showed up on my desktop and was working fine. Today, I made it a point to look at something and sure enough, it's not there again. Definitely an operating system issue. Just waiting on a fix now.

I followed all of the prescribed fixes on my Air with T2 and nothing worked. Until. I basically let the battery die. Didn’t touch it for 2 days. As it charged. Turned it on again and it all seems working again. So not sure which item solved it but that last seemingly helped somehow

Hi everyone!

The update to 14.4.1 fixed the peripheral connection issue. However, one problem persists. When I disconnect the USB-C cable from the MacBook, upon reconnecting, it doesn't recognize the monitor and the image. I have to restart the system to get back to normal. Apple is struggling to fix this issue.

I've been using Mac for 25 years so I don't have to worry about computers, connections, and commands. Unfortunately, it seems like that time has come to an end.

I tried one of the hard drives on my 2023 MacBook Air 14.2.1 and plugged directly into the computer it did not show up. Plugged it into a USB Hub and it did show up. So too k the usb hub and hooked that up to the MacBook Pro and the hub showed up. I have the settings set to ask to add any external device right now. But plugging the same hard drive into the usb hub and nothing. Reboot and nothing. This is insane. I need the hard drives to be connected to my MacBook Pro some how. So I took the only Apple thunderbolt cable I have and plugged the hard drive into that and it showed up right away. Are USB-C cables no longer compatible? Really?
