Question: Will it also work with a USB 2.0 port?
Document: Pawtec supplies you with a USB cable, and also a secondary cable in case you need to draw extra power from a second USB port. I attached the USB data cable to a USB 3.0 port on the hub, and the secondary cable to a USB 2.0 port on the hub. (The other end of that secondary cable goes into a special power jack on the back of the Pawtec.) The Pawtec powered up great and work flawlessly.
I needed a good USB 3.0 BD player and this device is perfect for its intended purpose. I have it connected via USB 3.0 port to my Dell laptop and it provides flawless performances in reading BD discs. I do not use it for recording BD discs, but I suspect it would be just as good a performer.
Excellent!3) The Pawtec specifications say it does support USB 3.0, and I got good transfer / burn speeds. My test was with thousands of .JPG photo images totaling 40.94 gigabytes. Attached to the hub, the burn completed in 54 minutes, for a data rate of about 12.6 mb per second. Attached directly to the MacBook Air's USB port, the exact same burn took 35 minutes, for a data rate of about 19.5 mb per second.
I am returning it for another player in hopes a different one may work with my usb ports. I tried it on usb 3.0, and 2.0 and neither worked even though other things do work on those ports.The tray sticks on it too, as you push the tray back in, it hangs and you have to push in the button as you slide the drawer in and it hangs on the top of the case. I definitely wouldn't recommend this product.
I have regularly used the Pawtec External USB 3.0 optical drive for two months now. It does everything that it was advertised to do, and it does it well. It is fast, needs only one USB bus of my computer to work, it plays and records CDs and DVDs, and it worked the very first time I plugged it in. I have had no reason to burn a Blu-Ray disk, but I'm confident that my Pawtec optical drive is up to that task.
(And especially: does it support USB 3.0? )Here's what I found:1) The list of compatible disks for this device is impressive. Right after I got it, I tested right away by burning to dual-layer Blu-Ray disks. These are 50 gb capacity and I nearly filled them with files -- flawless burn. It's great to be able to archive valuable stuff this way.2) It runs great off my hub, theManhattan Hub(161718).
Pawtec.com states that the issue is one with windows and that it only will work with windows 8 but with no updates after windows 8 because the usb 3.0 ports drivers become corrupted or something and won't recognize devices. This may not be a problem with the player itself, but it advertises itself to work with windows 8, knows of the problem and still sells it as being compatible.
I didn't even bother to use the power cable, only the USB cable and as it turned out, I didn't need anything else. The DVDFab and the Pawtec work very well together and are all I need to turn out perfect Blu-Ray discs every time...intended mission accomplished. I would recommend this writer/burner to anyone with the same purpose as mine. I will try and provide a timely update after using this item for a month or so...
This unit has not performed as advertised, either on my Surface Pro 2 or my friend's laptop. Exchanging it was not an option and I returned it postpaid to Amazon.
The aluminum case let's it travel well. When I plugged it into my surface pro 2 it was immediately recognized and no additional drivers had to be installed. Drivers are available from Pawtec's website. Reads & writes CD's, DVD's & BD's. Great portable drive.
Answer: Yes, it is downward compatible.
