Solved!

All usb port disabled after Win7 start

HP Recommended
ProDesk 600 MT
Microsoft Windows 7 (64-bit)

Hi everyone,

 

I just brought a few ProDesk 600 MT. After setup operation system, one of them seems locked all usb port after win7 start.

I can use keyboard/mouse during start up, including bios or the windows safe mode selection menu. However, once win7 started, all usb port are disabled, not even power supply. Which means no keyboard, no mouse. I can't do anything except power down the computer by push and hold power button.

Does anybody know why and how to fix this issue?

 

Thanks

 

Alan

Hi, Alan:

 

See if the info at the thread below resolves the problem if your PC has the Skylake chipset.

You're very welcome.

 

Perhaps you will want to install the latest USB3 driver from Intel in hope to prevent that from happening again.

 

Download, unzip and run the setup.exe file.
