USB Ports in Docking station don't work.

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.

They did not reinstall properly.  Now none of my docking station USB ports work, and a lot of things that I plug in to my other ports do not work, including a 7-port powered USB hub.
In the device manager, under "Other Devices", "Integrated Camera" (Port_#0006.Hub_#0004) and "Unknown Device" (Port_#0005.Hub_#0004) appear with yellow exclamations (no driver found).

Re: USB Ports in Docking station don't work.

Hello mate,

 

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

I was dubious at first, because I ran MANY updates. However, very near the end of the list of updates my devices finally installed correctly. What a relief! Thanks.

Thanks.. this was the right answer for me too.

Dock USB's didn't work

System Update repaired that.

Re: USB Ports in Docking station don't work.

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.
