Ive had USB 2.0 audio cables get static and then lose signal. couldnt for the life of me figure out why. Im guessing this has a lot to do with it. works for a while then starts dying. Cmon Apple. either say USB 2 is junk and not allowed anymore (block it in the OS) OR fix it ASAP! please!

Interesting. My iPhone will not connect to my 2020 Air using a USB-A to Lightning cable and either a USB-C to A adapter or a hub. It will charge but not sync. I wonder whether this is the problem.

Edited to correct: They both finally connected, it just took them a very long time to show up.

FWIW I don't think this issue is limited to new MacBooks?

I had some very weird problems yesterday with my 2015 MBP and peripherals connected via a CalDigit TS3 Plus Thunderbolt hub; a USB-C audio interface wouldn't work properly until I swapped the cable to plug it in via one of the hub's USB-A ports; and Bluetooth suddenly stopped pairing my keyboard + trackpad (both Apple).

Connecting the kbd + trackpad via Lightning to the Hub made them work OK and charge, but the Mac indicated they were "connected wirelessly" - if I unplugged them they definitely weren't. After chatting with Apple Support, I tried connecting them directly to the MacBook's USB port to get them to pair properly. Before that, doing SMC resets and using the BT Debug menu to remove the devices and restart the BT module had no effect.

I'm curious if there's some odd USB connectivity issues when going through a hub or BT... or if it's some odd interference issue.

Updated to Catalina today. So far, so good. Updated the CalDigit's firmware and got a new driver for my audio interface (lower latency than stock USB class-compliant driver).
 
These laptops are large to have a one USB-A port and an HDMI.
All they need to do is at least put in 2 USB-C, 1 USB-A, 1 HDMI.
I'm so glad my laptop has these ports and a few more, it's so much lets hassle in every way.
 
well, my experience told me, Thunderbolt is always better than USB-C. I have caldigit TS3 Plus docks, they are preforming very well.

Not necessarily relevant, but my experience with my 16 inch MBP is that the cheapest no-brand USB-C to USB 3.0 adapters work 100% of the time while my expensive Satechi hub works 90% of the time. More expensive doesn't necessarily mean better.

That said, I do very much miss the USB-A ports. USB-C has been "the future" for many years and it's still pretty much non-existent unless you're buying some high-end needlessly expensive designed-for-Mac accessory that comes in rose gold.

Depending on what you do, you can likely live without any form of Ethernet, floppies and CDs but there's no way around USB-A for the foreseeable future.

Right after I ordered my 2017 MBP three years ago I went to Amazon and purchased two USB-C to USB-A cables. For less than $20. That's mice nuts compared to the $3K+ cost of my laptop.

If you're a professional, why in the world would anybody futz with USB adapters when purpose-made cables are available? Makes no sense.
 
Does anyone know if the latest iteration of the official Apple USB-C to Digital AV Multiport Adapter (USB, HDMI and power) Model A2119 has this issue? Thank you

I didn't know that adapter has two (or more) iterations. Mine is arriving tomorrow, I bought it few days ago on the Apple Store, how do I know which iteration is mine?

This.

I got a few USB 3.0 to USB-C cables lying around whenever I need to back things up into my hard drives.

This article makes it sound like there is a problem with the Apple USB-C to USB "adapter".


MacBook Air and MacBook Pro owners who have one of the new 13-inch 2020 models released earlier this year appear to be experiencing problems with USB 2.0 accessories that connect to their machines though a hub or adapter.

There are a number of complaints about the issue on the MacRumors forums, Reddit, and the Apple Support Communities. Affected customers appear to be seeing devices connected to the Mac randomly disconnect, as explained below by a MacRumors reader.There are many other similar complaints about disconnection and freezing issues when using USB 2.0 accessories that connect to a Mac through a hub, though there seems to be no clear pattern as to which accessories are affected or when the issue occurs, making it difficult to determine what could be causing the disconnects.

MacBook owners have run into connectivity problems with all kinds of devices that require a USB-A connection, including mice, keyboards, and other accessories. Multiple hubs have been tested, which suggests that the issue is not caused by a particular brand of hub, and it also appears that most of the complaints are limited to USB 2.0 accessories rather than USB 3.0 and 3.1 accessories.

SMC resets, safe mode, Disk Utility repairs, different user logins, and operating system reinstalls have all been unsuccessful addressing the bug, which suggests that it may be something that Apple needs to fix in a future software update, if it is a software problem.

A Reddit user found that USB 2.0 devices that become unresponsive remain indefinitely in the System Information even if unplugged from a hub, while USB 3.0 devices behave properly, so this is one possible cause. He was able to solve the problem with a Thunderbolt CalDigit hub, but whether that fix will work for all impacted machines is unknown, and CalDigit Thunderbolt hubs are pricey.Multiple MacBook Pro and MacBook Air owners have contacted Apple so Apple may be aware of the issue and could have a fix in the works. Apple has been replacing some affected machines with new models, but users report that the problem persists even when a new Mac is provided.
