Customer FAQ

Q1.  Will the current requirement of my devices influence Anker hub's performance?
For maximum performance, connected devices should not exceed the combined current of the output of hub. Otherwise, output current may become unstable or disconnect entirely. See some commonly used devices' general requirements below:
250G Hard drive – 600mA
4G Flash drive – 100mA
64G SSD – 400mA
100M Network adapter – 500mA
Keyboards and mice and other peripheral devices – 100mA (or less)

The ratings above are estimates only. Please check your specific device's ratings before connecting to the hub.
Q2.  When my hub is connected through the ports on my Apple expansion card it fails to be recognised, why is this?
Mac expansion cards don’t tend to support non-storage devices (more info is available from your expansion card manufacturer's websites). It is recommended that you plug hubs into the Mac’s built in USB ports.
Q3.  My Western Digital hard drive cannot be recognized by your hub? How to fix it?
This could be to do with the firmware on your Western Digital hard drive. Try installing new firmware, downloadable from the Western Digital website.
Q4.  Why does Apple SuperDrive not work with your Anker hub?
Apple have addressed this issue and said that SuperDrive is only designed to work with USB ports on selected Apple computers. It is not recommended for use with USB hubs. (See Apple support article
Q5.  Why do my wireless mouse/keyboard not work closely with Anker USB 3.0 hub?
2.4Ghz wireless devices may have frequency interference issues with USB 3.0 ports so we recommend using a USB 2.0 hub instead.
Q6.  Do you have any driver for the hub?
Our Anker Hubs are plug-and-play so there's no need for extra drivers, but we do recommend updating your USB controller’s drivers and firmware to the latest version. This ensures a smooth experience using any USB devices. To do this you should identify the brand of your USB controller then search online, or contact your PC/motherboard supplier directly.
Q7.  Why is the transfer rate so much slower than the 5Gbps promoted?
The USB 3.0 transfer rate is 5Gbps and has a theoretical transfer speed of 500MB/s which is about 8 times faster than the USB 2.0 transfer rate of 480Mb/s with theoretical transfer speed of 60MB/s.
There are numerous variables that will affect USB transfer rate including data source and destination and file type. With all reasonable usage environments taken into account USB 3.0 can achieve average transfer speeds about 3 times faster than that of USB 2.0.
Q8.  Can I use my own accessories, such as power adapters and data cables, with the USB hub?
The USB 3.0 hub is equipped with its own power adapter and data cable to ensure maximum compatibility. Use of the provided cables and adapters is always recommended. If you have lost the power adapter or data cable, please make sure the specifications of any accessory you intend to use correspond with those provided. To ensure stable performance, the length of the data cable should not exceed 1m.
Q9.  Can I use the USB hub as a standalone charger?
We don't recommend using the hub as a standalone charger. The output current of the hub's USB ports is 900mA max. If you are using the hub to supply power, please make sure the input current does not exceed 900mA. The hub can’t supply enough power to iPhones, iPads or any other smart phones.
Q10.  Why is the computer failing to come out of Sleep Mode when the USB hub is connected?
This problem may be the result of one of the following:
    a. Improper power-saving settings. Right-click “My Computer”, select “Attributes”, then “Hardware”, followed by “Device Manager”. Double-click “Universal Serial Bus Controllers”, right-click “USB Root Hub”, click “Attributes”, then “Power Management”. Unmark “Allow computer to close the device to save power”, click “Yes ”, and then restart the computer.
    b. The computer can’t start because it can’t read system files. This occurs when the BIOS is set to “Start the Computer from the USB Device”. In order to solve this, change the setting to “Start the Computer from the Hard Disk”.
    c. For Mac users, please uncheck the box "Put the hard disks to sleep when possible" under Energy Saver.
Q11.  A surge warning appears on the screen when the USB hub is connected to the computer. Why is this happening?
When the input current requirement of a connected device is higher than the output current of the USB port, a surge warning may appear. Connect the USB hub to a power source to ensure sufficient power supply.
If the problem persists, please check to make sure the USB driver is installed properly, or click the USB icon on the taskbar and select “Reset” to make sure the USB device is being identified correctly.
Q12.  Devices are not being identified by my computer when connected to the USB hub, but they are being identified when connected directly to the computer. Why?
This problem may be the result of one of the following:
    a. Insufficient power supply. Please connect the USB hub to a power source.
    b. Compatibility issues between the motherboard and system. Please try refreshing the BIOS in the motherboard.
    c. Incorrect insertion or unplugging. Do not unplug the device when transferring data in order to avoid damaging the chipset.
    d. Improper driver installation. Under “Device Manager”, go to “Other Devices” and select “Universal Serial Bus Controllers”. If there are any yellow question or exclamation marks visible, uninstall the driver in “Device Manager”, then restart your computer. The driver will be reinstalled automatically.
Q13.  The hub keeps suddenly disconnecting from the device while transferring data. Why is this happening?
If this problem is occurring with properly-installed devices, it is usually due to insufficient power supply. When the hub is transferring data - especially large amounts - make sure it is connected to a power source. In addition, we recommend connecting the hub to your computer with the cable provided. If not, please make sure the cable length is less than 1m, so as to ensure stable data transfer.
Q14.  Why is my USB 3.0 device being read as a USB 2.0 device when connected to the hub?
This problem may be the result of one of the following:
    a. Insufficient power supply from the USB hub. Please connect the USB hub to a power source.
    b. Insufficient power supply from the computer’s USB port. Please connect the USB hub to the USB port positioned on the back of the frame, instead of on the front, to ensure sufficient power supply.
    c. The device is being plugged in too slowly. As a result of the USB 3.0 interface design, the system will recognize devices as USB 2.0 when they are plugged in too slowly, or section by section.

Compatibile with mid 2012 rMBP?
Do you know this Anker USB 3.0 7-Port Hub to be fully compatible  and stable with a mid 2012 MacBook Pro Retina OS 10.10? I gather this generation of rMBP has a stability issue with most USB 3 hubs.

AH231 9 port hub
Will the device operate also 1.0 and 2.0 USB speed?I hear there is a switch to turn the hub off and on. By turning the hub off while all the USB devicesare connected, will this cause a loss of drivers like when you plug and unplug a USB connecter inyour computer? If it does then I should leave it on all the time right?Thanks Tomy!  Thinking seriously on the purchase.

There isn't a power switch on the device but if it lost power whilst in use then it wouldn't affect the drivers.

It is backwards compatible with USB 1.0 and 2.0.

Hub goes to sleep
I am on an iMac (3.4 GHz Intel Coe i5, Fushion drive) running 10.9.4. I have the Anker USB 3.0 7-Port Hub connected. Sometimes when the computer goes to sleep, I will wake the computer up, but the hub seems to have gone asleep and doesn't wake up; the blue lights are not on and no device is recognized. I can only get it to respond by disconnecting and re-connecting the power cord. Is there a way I can prevent this? I have an external hard drive connected through the hub and I don't want it damaged.ThanksBrian

Did you make sure that you have the drivers installed for the hub?
Reply Report as spam Jul 19, 2014 at 5:05 PM

This sounds like it may be an issue with the Mac's USB port rather than the hub itself. Have you tried in a different USB port?

Please do get in touch with our CS guys at and let them know if you're having any further issues. They'll be more than happy to help.

Where can I buy this product ?
Hi,Do you sell this product in the Netherlands ? If so, where ?Does this hub provide enough power to serve a number of USB 3.0 hard drives and make them operate without any problems  (as many other so calles powered usb hubs are not able to do because they just don't provide enough juice)

Anker products are sold through Amazon. It looks like the closest place to that it's sold is Germany.
Reply Report as spam Jul 16, 2014 at 7:37 PM

You should be able to order from Amazon DE.

And yes, the dedicated power supply means it'll be able to work with several hard drives.

Daisy chaining?
Is it possible to daisy chain these hubs? That is, have the first one connected to the PC USB 3.0 port and the second hub connected to the first hub? 
Replies(1) Collapse Report as spam Jul 13, 2014 at 9:22 PM

Whilst this is theoretically possible we wouldn't recommend it, you'll suffer a lot of speed loss as well as causing instability during data transfer.

does this hub work with USB 2.0
Replies(2) Collapse Report as spam Jun 2, 2014 at 2:13 PM
Yes, it should do. I believe that all usb 3.0 devices are compatible with usb 2.0. USB 3.0 is quicker, so your usb 2.0 device will just work at it's normal speed.

Yep, it is backwards compatible.

Mac Mini won't boot with hub plugged in.

I just set up a brand new Mac Mini running Mavericks.  I attached the Anker 7 Port USB 3.0 hub and have two external drives attached to it.  I cannot reboot the Mini without unplugging the Anker USB 3.0 hub from the Mini's USB port.  Once booted, I plug it in and it works fine.  Really a hassle to have to dig out the Mini and unplug for every boot sequence.  Is there a workaround for this?

Replies(3) Collapse Report as spam Mar 24, 2014 at 1:06 PM

Perhaps you can't reboot because the two drives were still in use and computers have trouble shutting down when drives are powered on and spinning

common problem with USB hubs with memory sticks or HDDs plugged in during boot. Shut off the USB boot in the BIOS or unplug and storage devices while booting.

Hello, this is not a solution but a workaround, and unfortunately is impracticial in many situations. I use Parallels Access and need to be able to access my Mac remotely. This means that I need the computer to be able to reboot when not at home, and I need to have storage HDD attached to the hub. I've never had this problem with any other hub. Surely you dont have to unplu the hub everytime before you can boot up? It may be a common problem but that all the more reason why there should be a common solution!

It sounds like the hub is shot. But hope is not lost, maybe try using a different cable to connect it to the computer.
