I have the "USB Accessories Disabled Unplug the accessory using too much power to re-enable USB devices", I have been using an externally powered USB hub and this issue is new. Only occurs when I plug in my RK Keyboard to the USB charging cable. The cable is connected to the self powered hub and there is no issue with the Hub power as it is still charging the Macbook.

Update: I cleaned all my ports out with compressed air and this seems to have solved the issue so far.
Apple just released a MacOS update (14.4.1) that addressed hub issues users have been having. Recommend updating and see if this resolves the issue.
Many adapters, hubs, docks will not allow the full power of the charger to reach the laptop, plus only some a specially marked USB-C port will allow a power adapter pass through to the laptop. This shouldn't affect the power available on the USB ports.
This error message indicates your USB devices are trying to pull too much power from the laptop to power those USB devices. Make sure the connected USB devices are not connected to a power-in only USB-C port on the hub since many times a USB-C marked for power in will not allow data transfers.
Either you have one too many USB devices connected, or one of those USB devices is defective & trying to pull too much power. If you have too many USB devices, then make sure to get a self powered USB hub which has its own power adapter which gets plugged into an electrical outlet.
Having the same issue with the following:
Like with others, the error is being triggered when coming back to my office after being away for lunch or the evening--so the problem occurs either during or coming out of sleep.
The Brydge dock is supplying power to the laptop via the USB-C cable, not the other way around. The laptop battery shows as charging and is charging at a normal rate.
The error is being triggered by the Samsung SSD. This disk has been running for a couple of years as a Time Machine drive with no disconnects over multiple macOS updates.
When I swap out the Samsung USB-C cable (900mA, 10Gb/s) for an Anker high-speed USB-C cable the problem persists.
When I swap out the Samsung USB-C cable for an Apple charging cable (500mA, 480Mb/s) the problem seems to go away.
I'm currently working with Brydge and also giving this 'slow' cable some time to see if that is the fix. If so, that's pretty gross. From the data I've been gathering this is also looking like an Apple problem.
I get this message intermittently when coming out of sleep as well (MacBook Pro 16" m3 Max 2024). I have 2 Thunderbolt docks plugged into the MacBook. The first is OWC 10 Port Pro Dock (supplies 85W of power by the way) and the other is the Caldigit Thunderbolt 4 Element hub (supplies 60W of power).
Into these devices I do have some USB devices plugged - keyboard (SteelSeries), mouse (StealSeries), Audio (StealSeries) Stream Deck, Timemachine hard drive, Thunderbolt SSD. These are the same USB devices (less the 2 Thunderbolt hubs which are new) I had plugged into my 27" Intel iMC (2019) in which I never got this error.
I've tried moving the USB devices around, and even adding a powered USB 3.2 hub to plug them into, but still get the errors sometimes (if it was a reliable error to recreate this would be far easier).
It feels a bit like this is a software handshake error - that is when coming out of sleep it likely takes a moment from everything to activate and communicate, and that sometimes results in things being momentarily beyond limits triggering the error. Please note that NONE of the devices are actually disabled - they are all working when I get this error, and nothing needs to be replugged into to activate it.
I have this issue on my Macbook Pro M2 and Macbook Pro M3 with a Caldigit Thunderbolt 4 Element hub. Mixed cables around, different ports, even nothing plugged and still get this incessant notification.
I've updated the firmware on the Caldigit too but no change.
Also all devices that are plugged in work just fine!
OS: Somona 14.3.1
Hub: Caldigit Thunderbolt 4 Element hub
Devices plugged in (although issue persists when no devices plugged in, and the devices work)

Sounds like a hardware issue of some sort.... you may have a bad USB-C port. You should have Apple or an Apple Authorized Service Provider examine your laptop, power adapter, and charging cable.
Edit: I'm assuming you are connecting the charger directly to the laptop.

I don't know; many people seem to be having this issue suddenly popping up recently. It seems like a software/OS Update bug to me...
Very hard to say since not enough people are performing proper troubleshooting steps to provide any conclusions or describing their setup in detail. There are so many system variations & hardware people are using....all unknowns to us on this forum. More than likely one or more connected devices are causing a problem.
A macOS update could have changed how the USB ports work and some devices may no longer be fully compatible especially when mixed with another connected device. A lot of third party peripherals don't exactly adhere very well to standards, plus I find many people seem to like to use cheap no name brands instead of quality accessories (including cables). Even if a macOS update changed things, more than likely a third party device is ultimately at fault. People need to identify which external device or devices are causing their problem here. People will continue to experience the problem until they identify the device(s). No one else can even begin to help anyone until this is done.
Not sure if you will see this, but was there an explanation that made sense? I’ve read through the stream of comments and the only one that makes sense to me is that it is a glitch in the software. I change nothing (ignore the warning) and everything seems to continue to work just fine. I figure it is just part of the love/hate relationship I have with Apple.
@hwtech Does it matter if the laptop is drawing power from the hub? This problem started for me without any change in my peripherals and seemed related to the last Sonoma update.
Running an M1 MBP driving 5K and 4K ext monitors via two hubs plus a couple of external powered HDDs and a Wacom pad. The MBP is connected first to a powered hub, which is then daisy-chained to an unpowered hub. I also tried separately powering the laptop via the MagSafe cable without benefit.
Does an unpowered hub draw power from a powered hub between it and the laptop? Or directly from the laptop?
The warning pops up frequently then goes away for a tens of minutes and isn’t related to sleep/wake of the laptop.
This sounds like a bug but I guess I should do a NVRAM and SMC reset just to be sure after removing all peripherals. Then add them back one-by-one.

Seems like the Samsung SSD is using more power when it is waking up again.

I have found that some adapters/docks/hubs don't always allow the full power of the charger to reach the laptop. I have found this even with the Apple multiport Adapter.

Hard to say as it may be a Brydge problem. The dock is adding more accessories to a single USB-C port which is only capable of handling X amount of power. Sounds like the Brydge dock isn't providing enough power to all of the connected devices when the system is waking up. If you connect the Samsung SSD directly to the laptop and don't have this issue, then it is more likely a Brydge problem. If you do have a problem with the Samsung SSD connected directly to the laptop, then it may be a Samsung problem. Very tricky to troubleshoot since you would need to see the current being used for that port.
What is the brand and the exact model of USB hub?
Running Sonoma 14.4 on my M2 14" MacBook Pro. Sonoma: Apple's answer to Windows Vista. I too am just now getting this silly notification. I have changed nothing at all: same USB hub, same devices, same configuration. And now I'm being told this?? Sonoma is so darn buggy Apple can't keep up with it all. I don't know what troubleshooting I should enact since I haven't changed anything. I'll watch this thread for ideas because I'm stumped.
Thanks,

Same issue with no relief.
Started: Beginning of March 2024
Processor: 1.1 GHz Dual-Core Intel Core i3
MacOS: 14.4
Two 3.1 Thunderbolt ports. Only one is disabled at this time. Only happens when I plug in my charging cable.
HELP!
MacBook Pro M3, Sonoma 14.4
I have two monitors plugged in. One via HDMI and has power going directly to the wall, never has issues. The second is a Lenovo 32" that has power going to the wall and uses the USB-C for connecting to MAC. Constantly get USB power warning and half the time I need to unplug the Lenovo monitor and plug it back in to get it to work.
Why is my RK Keyboard causing USB Accessories Disabled error?
