Usb C hub not working on MacOS Ventura

Yeah, I have had a problem with two USB C hubs on my macbook air M1, and not just with Ventura. When it happened with the first one, I assumed that I'd broken one of hte connectors (it's a wavlink hub , which has two USB C plugs that go into both ports on the macbook air.

Now I've investigated, they both work for power, but neither of the USB ports seem to work beyond that. I can see lights come on when USB sticks or hard drives are plugged in, but they don't get recognised in finder, nor are they present in Disk Utility.

Neither does my HDMI adapter work when plugged into the USBC input on the hub.

I'm very interested to work this out, it's kind of stuffing up my work, a lot.

All the drives etc, work when plugged directly into the computer via an adapter, but not into the hub. Aaaaargh, feels like it should be simple.

Yeah- how come? I only hit reply. But yeah- first time on here . How come some Apple guys can’t just answer the question?? I’ve tried a few of theses suggestions and nothing’s working so far.

You weren’t the person who marked the answer as “Best Answer” as you are not the original poster.

This is a user-to-user forum. Apple’s participation in this forum is minimal. If none of the suggestions given have helped, it is perhaps time to have Apple evaluate your device:

I have a G-tech ES pro and G-speed (raid boxes) I use for Network show editing (avid). They worked great (mounted) on my INTEL I7 Imac untill I updated from 10 to 13.2. Oddly, they mount fine on my macbook pro 19. No hard drives will mount on either of my the 2 thunderbolts or 4 USB 3 ports. I was able to get a "J5create" hub out of one of the thunderbolts to run my two additional HDMI input monitors. That took some fanagleing (unplugging re plugging, power off on, etc). All ports do send power to drives but will not read data. Very strange. I have to try my I/O Avid Artist (Black Magic). So, bottom line, 13.2 does not have "the fix." Again, they mount fine on my macbook pro with 13.1 ventura. It seems that "data read" is turned off on intel machines with no "settings" to fix.

I have 2 Anker. Thought it was broken, bought a new one. Same issue. Everytime I boot, I have to pull the hub out and reinsert. It has 2 HD and microphone.

Sucks. Just happened with an OS upgrade.

The accessory option is not found in my settings as someone else suggested.

MacBook PRO 14 M1 MAX

Ventura 13.4 (updated 30th of May 2023)

I have the same problem with Satechi Multi Adapter. It doesn't work when the device doesn't have its own power supply.

So pen drives, USB-A -> USB-C cable (data trasfer), bluetooth adapters external drives don't work.

But when I plug in a HDD drive with external power supply it works or the HDMI slot works pretty nice.

The hub has SSD M2 enclousure - it detects the disk but when I want to upload some data on it, the disc stops the transfer and is removed automatically.

I tried usign didfferent USB-C port, I did the SMC reset and it doesn't help.

Are there any other options?

Follow on from my prior post - update: after a few more weeks of frustration, Anker provided a new hub. In the meantime, I had already given up on them and bought a Kensington 5700T thunderbolt. That worked well until today - no more power via USB A. I am afraid I will have to go through another long discussion with Apple support.

Edit: after Macbook restart, power was restored to the USB A (mouse) and (android) phone.

Interestingly I was asked if I want to allow USB to get connected after setting "always ask" What it does: It only asks for the hub to be allowed. When plugging in SSD or anything else there is no more dialog asking to allow. So for me it´s a big bug in system. System should also ask for peripherals plugged into the hub but it doesn´t. So that´s the point where developers have to bugfix in my opinion.

This is the ultimate fix. This is what helped me!

Just put "Allow accessories to connect" to "Always".

Everything works now again.

Hi Jazzy, Thank you for your reply. But with a Non M-chip Mac there is an issue:

It’s clearly a software issue, considering I’ve used two completely different self-powered TB4 hubs and they both exhibit the exact same issue: random disconnecting of my SSDs.

I am guessing this is the right answer - I have had problem intermittently with several devices and this setting of "Allow accessories to connect" automatically when unlocked solved the problems.

My 2020 Macbook Air kept crashing with sudden USB disconnection from the USB dock when using the USB-C docking station with an external display every so often (like once every 45 minutes to one hour) after I upgraded to Ventura OS. I suspect it may be due to the USB-C privacy protection feature from the new OS. The docking station I use is the Totu USB-C Dock TT-DC002A (https://www.amazon.com/TOTU-Upgraded-Universal-Charging-Extended/dp/B0838WTFD1/ref=sr_1_3_sspa?crid=10T4MHAMHEUDS&keywords=Totu+USB-C+Dock+TT-DC002A&qid=1666989763&qu=eyJxc2MiOiIwLjg3IiwicXNhIjoiMC4wMCIsInFzcCI6IjAuMDAifQ==&s=electronics&sprefix=totu+usb-c+dock+tt-dc002a,electronics,890&sr=1-3-spons&th=1). I have tried using two different docking stations of the exact same model and reverted back to the Monterey OS without the disconnection issue, so I have confirmed the hardware is functional. I appreciate it if someone could have a solution to the issue. Thanks!

Same issue here. Never had an issue charging until MacOS Ventura. The MB will say it's charging but will QUICKLY run down to 0% without me even noticing since it doesn't tell you it's going to die if it has a charge going. Something is very wrong with the OS.
