Question: Is it backwards compatible to USB 2 and USB 1
Document: I suppose I did not read the description/comments closely enough, because this is ONLY a USB 3.0 front end. It is NOT backward compatible with USB 2.0, even if the card you are plugging it into is backward compatible. It works fine, if you will only be using USB 3.0 devices. I will be replacing it soon though, since I still have several USB 2.0 devices I need to still access.
I plugged this into a new Megabyte motherboard under XP with USB 3.0 drivers, and have no USB 2.0 compatibility and erattic 3.0 connection.This is a four-port and the motherboard conector does say it is for two-port. I just bought a two-port as a test.Wish me luck.FJC
It has the additional benefit of having the &#34;FAST CHARGE&#34; option on the fourth port. I tested this out with my Samsung Galaxy S5 (with the phone's USB 3.0 cable) and confirmed that in Fast-Charge mode, the PC will charge my phone just as fast as the Samsung S5 charger, or in half the time of a USB 2.0 port or 1000 mA or less charger.
Main reason I purchased this was to &#34;flesh-out&#34; my new computer case. My newly built PC (from Amazon purchased parts) has two USB 3.0 ports in the back, but the motherboard has an additional 2 port header for front panel ports. My case came equipped with two front-panel USB 2.0 ports but no USB 3.0 ports.
I rebuilt my computer but I kept my Lian Li case. It looks mush better than other cases, even Lian Li's new cases. But it didn't have a usb 3.0 front header for the nifty usb ports at the front bottom of case (they are the old usb 2.0).So I bought this port. Looks nice in the front of the case (behind the closed door). So now I have easy access to 4 more 3.0 USB ports.
So far it gives the correct transfer rates according to USB 3.0 certified rates for every 3.0 drive. I am giving it 2 stars only because I found out that when I was trying to transfer some files (around 17GB) between a Sandisk USB 3.0 extreme pen drive & a WD 2TB USB 3.0 My Passport drive the transfer halted many times. Twice I got the error that the pen drive could not be found. It seemed like intermittent disconnection.
the second one I received works great. The charge function is fast and I love having usb 3.0 up front, especially since my 2 on my HAF X broke.
You do need to have USB 3.0 support on the motherboard or on an expansion card.
works well fits nice, came with both kinds of internal connection cables, makes my USB 3.0 flash drive super quick
After installation and testing the USB ports require some force to plug anything or remove anything from them.I feel like after awhile something may come loose from the force needed to plug and unplug things.Other then that it functions and looks great and at a great price!
Answer: The ports will work with USB 1.1 or 2 devices.  But it has to be plugged into a USB 3.0 card.
