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.
