I have 2 usb ports on my laptop and I have a powered hub plugged in. I only have 4 usb devices plugged into it and am getting an error at boot stating not enough usb controller resources.

This seems out of whack. Why can't wino 10 on a brand new laptop, support 4 usb devices? I should be able to run at least 10 minium. This happened on my old desktop as well.

What is causing this?
 
what devices? if it does the same thing on two systems, its prob something youre using
 
I am using a corsair keyboard k70, corsair mouse, usb headphones dock just to power and steel series usb headphones. I removed the usb headphones and the error went away.

Just 4 devices causes this? Kinda shitty imo.

Depending on device type it may use more than one USB endpoint. One USB3 port supports 16(?) endpoints.
So best advice is to move the keysboard and mouse to a separate hub/different USB port.
 
hub is powered? the error is your bios/hardware on boot up, not really windows. look for and turn off xhci in bios, see if it helps. or update the bios and chipset drivers. or shuffle things around to see if you can get a combo that works.

Are you sure that the hub is supplying enough power? What is the power output on the power adapter for the hub? Modern USB keyboards with the current rainbow-LED fad suck up much more power than a traditional keyboard. A headphone dock that is used for recharging headphones has the potential to use a lot of power also.

Purely in terms of data, a single root USB port should be able to theoretically support up to 128 devices via hubs. But whether or not all of those devices receive adequate power is a completely different issue altogether.
 
Why would a retail item sold at best buy come with a power adapter that can't support the device it's sold with?

That is pretty unreal. Why sell the device if it can't do what it's supposed to do?

I am going to just plug my headphone pod case into something else. Don't need it connected all the time.

Thanks!

The hub works fine when not expected to provide power beyond its limit.
You can either get a hub with a PSU capable of providing more power, or as you have chosen, plug the power hungry device into a different USB port.

because there are different power outputs on different hubs, just like usb phone chargers. you devices are drawing more that it can provide. not rocket surgery...
flip it over and look at what the label says.

Why can't the lighter socket - to - standard NEMA adapter that I bought for my car power my weed whacker + leaf blower off of a splitter? It uses the same plug and it plugs into the car so it should just work smh
 
Dude...your insane.

You don't know me from a hole in the wall but you're making broad accusations about how I learn educationally? This is why I hate the fucking internet. Have a good day dude.

Unreal.

Thought there were standards when it came to usb power. Guess not.

There are, just like there are standards for the power outlets in your home - but that doesn't mean you won't still trip the circuit breaker if you plug in too many power-hungry devices at the same time. It's really no different with a hub.

A hub is primarily meant as a means of splitting the USB data signal. How much power it supplies will be limited by the power adapter for the hub, but they aren't really meant to act as a multi-port charger for several power hungry devices. You should select your hub with an idea of what you are going to use it with. Many devices, like a USB printer, full-sized external hard drives, most USB DACs, etc have their own power source and don't require the USB ports to supply any power. Other devices such as USB thumb drives, traditional mice & keyboards (without the LED lovefest), USB SD-card readers, etc will use USB power but not very much. Because of this, there are a lot of cheap hubs out there that really don't supply very much power, yet they generally still work fine.

If you need a hub that you can use to charge multiple devices that have rechargeable batteries as well as even more devices with tons of LED lights, the hub will need a reasonably beefy power supply.
 
2 different setups and same "not enough usb controller resources" .. I've never seen this error on any PC I've messed with .. and I've messed with a lot of PC's/Laptops ..

Hmmm, I'm thinking ..
