Hello, I have an HP EliteBook 8460p laptop in which I have 2 USB 2.0 ports and 2 USB 3.0 ports. The problem is that on all ports it is so that I will capture the supply voltage but the USB 3.0 ports do not have communication (after connecting the pen drive or other device nothing happens). I have installed the drivers (the laptop is in use and there was a folder with all the drivers), I also checked in the BIOS if the ports are disconnected but everything was OK. After all, I disconnected the ports and turned them on again (it did nothing). I have Windows 7 Home Premium, additionally I downloaded from the HP website https://support.hp.com/pl-pl/drivers/selfservice/hp-elitebook-8460p-notebook-pc/5056942 the driver named Renesas Electronics USB 3.0 Host controller driver and reinstalled but it did nothing. I will add that the device manager does not display any drivers. Anyone know what I can do about it?
Run bootable linux from USB. Write if the ports below work correctly. I have already encountered the situation that, e.g. mouse or pen does not work for me in USB 3.0 (Lenovo), and in USB 2.0 it already does. It's hard to say if it's a childhood disease or drivers. List the options you have in the BIOS about USB. Maybe you can switch something there. I'm afraid it's the fault of this particular pen. Every now and then there is a situation that from one pen it is impossible to bet the system via USB 3.0, and on the other so. Such "PC magic". ; (

In my opinion, this may be the motherboard's fault.
Sure. And most of the fault is the USB standard from 2.0 to 3.0 ...

I found this "something":
Switch. Write what effect. In total, the problem touches the tip of the UEFI iceberg. You would have to give us in what mode - emulation or UEFI - was the system put in place , it completely changes the way the "peripherals" communicate with the motherboard, And this is a problem in the subject!

In the worst case (!) You will have to put the system back on .

Ehh .. write what exactly you connect. There may also be a physical fault with the disc, as he wrote @ chrupek311 , but after "examining" PC with linux.
I checked the ports on 4 devices (2 flash drives, optical mouse and Arduino board) on USB 2.0, everything works while USB 3.0 works on Arduino but I can't communicate with it (I have power) and the mouse just lights up and goes out. And as for bootable linux from USB I have no idea what's going on (I don't know much about computers).
https://support.hp.com/pl-pl/drivers/selfservice/hp-elitebook-8460p-notebook-pc/5056942 Install the chipset drivers. If that doesn't work then download some Linux (like Ubuntu), load it on a pendrive with Rufus and start your laptop by loading linux. If the USB ports still do not work, it may mean: - the controller in the BIOS is disabled. You can try to restore the bios to factory defaults. You can also update the BIOS. - controller released by connecting to the USB device of unknown origin - damaged path / ribbon due to unintentional disassembly of the laptop or falling.
Maybe you don't have the driver installed. I found: https://support.hp.com/pl-pl/drivers/selfservice/hp-elitebook-8460p-notebook-pc/5056942 NEC USB 3.0 Controller Firmware Update Utility under "Firmware" (for HP as usual, total mess, brrrr). ah, there is also your Controller Driver Renesas Electronics USB 3.0 Host under "Controller-Chipset". I suggest in this order: 1 firmware upload 2 reboot 3 installation with "Controller-System kit" -> Intel chipset installation tool 4 reboot 5 installation from "Controller-System Kit" -> Controller controller Renesas Electronics USB 3.0 Host ... and how about linux?

ps. It's nice as if you checked some Everest or ifa what chip on your board is responsible for USB 3.0. Please provide, because I have conflicting info from HP. Is it NEC or Renesas finally ...?
- controller released by connecting to the USB device of unknown origin
And as for bootable linux from USB I have no idea what's going on (I don't know much about computers).
Here you have e.g. Mint to download: https://www.linuxmint.com/download.php Do not write that you do not know about computers when it is only installed on a USB pen and sets UEFI to boot from USB. That's all. You are running linux. Run a USB 3.0 port test under it.

At what standard is Arudino? The mouse also does not work as 3.0 probably and should be in 2.0 (does not change the fact that with 3.0 should work
In the BIOS I found something like this:
It's an archaic "circus" BIOS from HP. Look for the XHCI and USB 3.0 options, show us all the tabs and that so that everything is visible and not cut.
