Windows 10: Windows 10 - USB Port not proving enough power

Hi All,



I have a problem using my USB port when connecting an external 2,5" USB self powered hard drive. Can you help me ?


I'm using a fresh Windows 10 1909 x64 up to date, with all the manufacturer drivers installed, drivers who have nothing specially related to USB, except perhaps the AMD Chipset Driver but I don't know if it acts on this the motherboard is an MSI B450M Mortar Max.


The problem is that when I connect some hard drives on an USB port, either a front port, a back port, an USB 2.0, 3.0 or a 3.1 one, with its short USB 3.0 cable :

- sometime not often the hard drive mounts and work flawlessly

- but the vast majority of time, it powers up, seems to have some difficulties with the power I mean the LED does not blink but I can hear the disk head doing strange things, and it does not shows up into the explorer. In the hard drive manager, it is not present


This happens with branded-cased-allinone hard drives as well with self-made case hard drives, and also with some USB flash drives. Curiously other same kind of USB flash drives I have in double or triple same model-capacity-andall works fine.


Everything is new except the hard drives but they were very lightly used, I have a 300W Gold power supply used at 120W at max on idle and 150W at full load.

I've tested many things, including trying to force an update of the USB drivers through the device manager but they were up to date, disabling the Power suspend of the USB ports, and many other things.


In contrast, when testing all of this using a Linux Mint 19.1 XFCE x64, and I have absolutely no problem at all. Never.

That leads me to the conclusion that it's not a harware related problem.

Windows updates - USB Port not proving enough power

Hi All



All my USB port were working just fine until the last Windows update, 03/12. I have a 4 port USB hub plugged in to one of the USB ports on my PC and every time I add a USB thumb drive I get a message saying "USB Port not proving enough power".



I have gone in to device managed and uncheck "Allow this computer to turn off this device to save power" on all my USB Root Hubs and generic USB hubs.



Is anyone else experiencing this since the last Windows update? Or is it just a coincidence?



Could is be I am having power supply issues? If so, how could I check the power supply?



Thanks in advance.



Ewan.

 

Power Surge on the USB port?

Hi Bob,

When a user tried uninstalling the USB drivers, it usually installs itself again when the computer restarts. It is a fact that most of the Mouse and Keyboard nowadays are connected using USB connection instead of their traditional PS/2 port. We suggest that
you visit the link provided and follow the steps provided:
USB has malfunctioned and exceeded the power limits of it's hub Port , you should disconnect the device

Kindly let us know if you need further assistance.

Is your 4 port USB Hub a Powered one? Meaning it has an A/C plug to obtain and provide its own power? If not you probably need to get one.

Another factor could be not all the ports on your computer are powered the same as often only one or two are of a higher power. Try using other ports on the computer to plug that hub in.

Best to just use powered hubs.
