I've been getting this message whenever,i try to plugin my external 3.0 Hard disk or flash disk on 3.0 USB port,i tried every possible solution to fix this problem (download drivers,re-install the USB driver and rest it many times), other than that the same 3.0 USB port works well with USB wireless mouse or any USB devices.


PS Asus laptop windows 8 pro 64 bit,i have only one 3.0 USB port (i got the same problem on windows 7).

Does your harddrive comes with 2 usb cords or just one with external power supply? Either way it should have 2 connectors on it, one for data transfer, and one for own powersupply. Both connections must be made in order to make it work properly.

No i have the normal hard-drive that comes only with 1 USB cords ,that hard-drive works well with USB 2.0. my problem is on USB port hub 3.0 itself.

Have you tried this?

Power Surge on USB3 Hub Port

If you receive the USB3 error "Power Surge on Hub Port, A USB Device has exceeded the power limit of its hub port, (For assistance in solving problem click this message)" follow the procedure below.


1. Download and unzip USB3_Fix.zip from http://www.digitalintelligence.com/files/USB3_Fix.zip.

2. If your Universal Serial Bus controllers/USB 3.0 Host Controller driver is prior to version 2.1.39.0, apply the USB3 driver upgrade (1-RENESAS-USB3-Host-Driver-v2.1.39.0\setup.exe) and reboot if prompted. If your driver is this version, or beyond, skip this step and go to step 3.

3. Install the Firmware Updater (2-USB3-Hub-FW-Upgrade\Usb3HubFWUpgrade_Setup_V0.35.exe) and reboot if prompted.

4. Delete the C:\Program Files (x86)\USB3 Hub FW Upgrade Tool\Bin\810_0880.bin file that was just installed.

5. Copy the 2-USB3-Hub-FW-Upgrade\810_0880_disable_oc.bin file into the C:\Program Files (x86)\USB3 Hub FW Upgrade Tool\Bin directory.

6. Execute the "USB3 Hub FW Upgrade Tool" which you just installed in step 3. Once the new firmware is installed there will be another USB warning, but this is normal.

7. POWER OFF AND RESTART THE SYSTEM. When you run the FW Upgrade Tool it should now show version V8.80.

Also you may consider to buy double headed usb cord which will provide more power output from another USB port.

Lot of people have issues with their usb 3.0 ports on laptops. And it's power issue for sure, and some of them tried to disable stand by and hibernation which helped in some cases. Best thing to do is to try connect it with double headed cord. It has been proven to help. Only thing is that you'll lose aditional USB 2.0 port in that case.
