I bought this to use a webcam with a built-in mic on my Microsoft Windows Surface Pro 8. When I first plugged in the webcam both the camera and the mic were recognized, however the mic was not picking up sound. After double checking the device settings, my privacy settings, the device drivers, and everything else I simply unplugged and replugged the camera in. Then everything worked as I had hoped. Great value for a great product. I trust Anker to reliably protect and provide stability for all of my devices. Simple product, plug and play. Sleek, simple design

Great piece of equipment. Worked for mouse, hard drive, and digital camera all into a laptop.

Works great. I used to plug in a mouse, an external hard drive, and an overhead Nikon digital camera for historic digitization of documents and books. It small and compatible and there were no connection or power problems. It feels well built and sturdy and the cord connection to the device is strong and flexible.

Great for retro emulation!

Got this for a retro emulation setup. Worked great. No issues whatsoever. Works on apple as well. Its a basic usb hub, but doesn't feel cheap. Got it on sale, which made it even better!
