USB ports on U2713H stopped working while using them
I need help to a problem I cannot seem to find an answer. While using the computer, keyboard and mouse connected to USB-port on the side of my U2713H all USB-ports on the monitor stopped working.
So far I have established:
- Upstream cable connected OK.
- Keyboard and mouse work if plugged in to the same port on computer as upstream cable.
- No obvious problems in Device Manager.
- Have tried Factory reset on screen.
Any suggestions?

Thanks for quick reply.
Yes the USB devices I tried seem to get power.
I don't have another uplink cable. Following your advice I will purchase one and try. If still not working I will revert for a replacement as the monitor is less than 2 months old.

fjessing,
Your issues could be that the operating system has set USB to go to sleep. Connect the monitor USB Upstream cable from the bottom of the monitor to a USB port on the rear of the PC. Once connected, the USB ports on the monitor will be active in the operating system. But, due to issues of using the monitor USB ports and powersave modes, the following USB devices should NOT be plugged into the monitor. They should be plugged into USB ports on the rear of the computer -
Mouse, Keyboard, USB Hubs, USB hard drives, Wireless Mouse/Keyboard transmitter, Printer, Scanner
Once you have those devices plugged directly into the computers USB ports -
* Open the Device Manager
* Open Keyboards
* Right click the device
* Left click Properties
* Left click Power Management
* Remove the check from "Allow the computer to turn off this device to save power"
* Be sure "Allow this device to bring the computer out of standby" is checked
* Click OK
* Open Mice and other pointing devices
* Right click the device
* Left click Properties
* Left click Power Management
* Remove the check from "Allow the computer to turn off this device to save power"
* Be sure "Allow this device to bring the computer out of standby" is checked
* Click OK
* Open Network adaptors
* Right click each device one at a time
* Left click Properties
* Left click Power Management (some will not have this tab. skip them)
* Remove all checks
* Click OK
* Open Universal Serial Bus controllers
* Right click each device one at a time
* Left click Properties
* Left click Power Management (some will not have this tab. skip them)
* Remove the check from "Allow the computer to turn off this device to save power"
* Be sure "Allow this device to bring the computer out of standby" is checked
* Click OK
* Close the Device Manager and restart the computer. Now those devices will not "go to sleep"
