how to disable USB 3.0 in BIOS on Latitude 6430s

Dear all,

I need to disable USB 3.0 (Intel Panther Point USB 3.0 controller) support in BIOS on my Latitude E6430s. The BIOS vA14, BIOS Revision: 4.6.

Unfortunately there is no BIOS switch to do this. It is possible to disable USB support for external devices completely, but it is not an option.

Is there any chance to get rid of USB 3.0 on BIOS level? Perhaps some development BIOS release etc.

Appreciate your assistance.

Thanks

jim

Hi ,

Thank you for writing to the Dell Community Forum .

To disable USB 3.0 ports I would suggest you to restart the system  go to system BIOS then under system configuration click on USB configuration then choose to disable External USB Port by this USB 3.0 ports are disabled and devices attached to the USB port cannot be viewed in the operating system .

I hope this helps. Please feel free to write to us in case of any further queries. 


Have a great day ahead !

Thank you for answer.

Disabling USB External ports will disable all USB devices connected to external ports. This is not what I need. I need to disable USB 3.0 mode only and be able further to use USB 2.0 and USB 1.0 devices on external port(s).

Thanks

USB 2.0 and 1.x devices are compatible with USB 3.0 ports.  There's no way to force the USB 3.0 ports to act as 2.0/1.x.  It's either on or off.

Thanks for response, ejn63. Right, there is no way to force USB 3.0 to act as 2.0/1.x. But it is not what I need. My intention was to disable USB 3.0 controller in BIOS, so only ports served by USB20 controller are available for operation (as far as I remember USB ports on one side of Latitude are served by USB30 controller and on the other side with USB2.0).

The Latitude 6440 with Haswell CPU  (newer than my notebook) for example has an option in BIOS to disable USB 3.0 controller. USB2.0 ports are functioning quite well with disabled USB30 .  This is what I would like to have in my notebook.


Thanks.

Hi, JIM78! I met with the same situation as you were. Did you figure it out? How can I just disable the USB3.0 in BIOS for my Dell Latitude E6430? Thanks for your time. Please kindly show me the details since I really need to figure this out as soon as possible.

Thanks!

Thanks for your reply. But the thing is that I just need to disable the USB3.0 ports but keep the USB2.0 ports for further usage. Is there any way to do that in BIOS or other methods?


Thanks!

Hey Kevin,

unfortunately I have not resolved this question. Disabling ext. USB devs in BIOS on E6430s results in dead USB ports under OS (at least all USB ports on docking station). Hence to achieve my goals I have to boot laptop in Windows.

Regards,
