I use this hub with my Mac and it is great. I just plugged into my USB port on my MacBook Pro and have never had a problem with it. You can optionally power the device with the included AC Adapter, which lights up a bunch of green lights and one brilliant blue light at the top of the green lights. This blue light is extremely bright for its size and may need to be covered if you are sleeping in the same room with it. I have plenty of open slots for additional devices. If you are using this device vertically in the stand there is a front USB slot for you to attach your flash drive without any effort. Everything (at least with a Mac) is recognized and ready to go once it is plugged in. I would highly recommend this hub - you can't find anything as nice for the price that is powered.
