I was having trouble getting a USB device to connnect. On the advice of my systems guy, I used the device manager to uninstall all USB devices, expecting them to reinstall on reboot.
Solved! Go to Solution.

The best way way is to run system update and let it find and install the missing driver.

The Problem occurs with both Win 7 and Linux Mint on a 4336 docking station with T510 or T520.
The problem is no power to any of the four USB ports on the docking station even after update with system update.
The crazy part is that the ports are powered until I enter my password and then they shutoff the +5 volts.at the dock ports.
Everything else ( VGA, Ethernet,etc) is fine.
The USB ports on the laptop coniinue to work.
I have tried the trick of deleting all USB ports under W7 and letting the system reinstall the ports but ir results in no change..
I have used docking stations with other Lenovo laptop models with no problems.

No, I still have the problem with the USB ports on the dock working in reverse.
The ports are on at powerup and then turn off when either Linux or w10 loads.
System update is about worthless because all it does is present a page of drivers with little actual information on how to use them.
No dock updates are listed.
Lenovo used to be much better with things like this.
I would be OK with just buying another dock but it might just have the same problem.
The ports in the laptop are fine.
The problem is the same on both the t510 and T520.
I really can't believe that I'm the only person in the whole wide world to ever have this problem.

I too have the same issue. It just started recently. I have a T450S and have been using it with the docking station for nearly a year with no issues. I recently added dual monitors but the issue didn't start for at least a month after that. I am running Windows 10.

I just fixed mine!! I just realized that the system updates they were talking about were Lenovo system updates not Windows!! So I had to install the Lenovo Bridge (?) and it scanned for missing/out of date drivers and other system updates. There was a critical BIOS update that was pretty scary but I went for any recommended or critical updates and after reboot my USB ports were back. My best guess is that a recent Windows update may have "broken" a driver. So that's something to add to my update list.
