USB 3 Non-Op

Brand new X1 Carbon 3443, Windows 8 Pro. USB 2 works fine but he USB 3 connector(right side)  does not recognize any devices (2 or 3). It appears to pass power but not data. I have updated the BIOS G6ET66WW (2.10 ) and patched using both the Microsoft Updates and the Lenovo update programs. The Lenovo Solution Center tells me in its Device Manager that I have 2 unknown and uninstalled devices, but the Microsoft Device Manager is not aware of them and shows everything fine (no !'s). Any guess as to what to look for or try before calling support on this?

Re: USB 3 Non-Op

Jamesfee,

 

The first thing I would check is to make sure the USB ports are correctly configured in the BIOS (if you haven't already). Upon booting your machine, press "Enter" to interrupt normal setup. A menu will appear. Hit "F1" to enter BIOS. Navigate to "Config" and then select "USB." In this menu, you should see some options for your USB ports. Ensure that USB 3.0 is set to either "Enabled" or "Auto," depending on how you wish to use it. "Auto" will automatically switch its power mode between USB 3.0 and 2.0 depending on what type of device is currently connected, whereas "Enabled" will always have the 3.0 power mode enabled. Make sure these settings match your wishes. 

 

Good luck, and let me know how it goes,

 

Adam

Re: USB 3 Non-Op

Thanks Adam. Been there, done that, no luck.

 

It's strange. The Lenovo Solution Center knows that there is something missing - it lists 2 unknown; Not Installed devices but Windows 8 is oblivious and doesn't see them.

 

I went through with Lenovo Support but they don't have an answer either. There appears to be a lot of messaging on Windows 8 and USB 3.0 and none of it is good. I need the machine but do not need Win 8. Support is sending me Win 7 disks - let's see if that clears up the problem.

Re: USB 3 Non-Op

Hi again, jamesfee

 

If that did not solve the issue, my next recommendation would be to make sure your chipset driver has been updated, which can be found here. You have already updated the BIOS, but the chipset should also be updated to ensure maximum compatibility with the USB 3.0 port. 

 

Good luck, and keep me updated,

 

Adam

Re: USB 3 Non-Op

OK, here goes... Upon receipt of the machine (X1 Carbon - Win 8) I dutifully patched everything. That process left me without the USB 3 functioning (and of course I had no idea if it was working before I started this journey. There are no Win 8 drivers for USB 3 listed but there are for USB 2. The USB 3 drivers are for Win 7; and I thought ... Hmmmm how much difference could that really make.

 

Fast forward many hours and a couple of these posts and it turns out that the way to correct the issue came about by uninstalling everything USB in Device Manager and letting the system update itself after a reboot. This whole incident brought to mind the old quote about "the road to Hell being paved with Good intentions"

 

Thank you all for your help and suggestions
