Normally, the Dell Pr03x has 2 USB3 ports (and 3 x USB2). Are you sure that it is a Pr03x ?

My "docking station" has a total of 6 USB ports. I can't determine which are USB2 vs USB3.

It automatically loads it's drivers and is usable on both my Dell and HP laptops. There are USB 2.0 and USB 3.0 version ports. I've had other USB sticks that will work in one version of the port and not another. Look into that being the problem.

It's not so much dell or something else My previous dell laptop had the slot that the card required and it worked great, I just got a new laptop and I was sure to pick a model that already had USB 3

1 x PCI Express 3.0/2.0 x16 Slot. The back of the box lists USB ports as "2 x USB 3.0/2.0 ports & 8 x USB 2.0/1.1 ports", but I assume they include possible USB connections via the ports on the front panel of your PC case and whatnot. USB ports available strictly on the motherboard are 2 x USB 3.0 and 4 x USB 2.0. Hope that helps! Here's a picture of the specs on the back of the box: http://i.imgur.com/A3NcRrY.jpg

Yes, there are 2 USB 3.0 ports on the mother board and depending on your case the mother board is setup to support USB 3.0 connections on the front of the case.

This piece requires two USB connections, one for power and the other for data transfer. I do not know if Surface Pro3 has two USBs. Also, I am not sure if the Pro3 has the driver for this device.

Yes for you to get the USB 3 speed out of the 2 USB 3 ports, as it has already been mentioned maybe you could find a cable to convert 3 to 2 but you won't get the 3 speed, which is nice.

There is one USB 3.0 and two USB 2.0 ports. There is also one VGA and one HDMI port, as well as an ethernet LAN port, and an ear jack plug.

Well it does have three ports and I believe one is 3.0. Not absolutely certain on it, because I don't really know much re differences between the two types.

Mine has all four with the blue plastic that usually indicates usb3.0. A big boon that's not advertised is that there is a second drive bay, so you can add another hard drive or even a ssd. I have added an extra drive but it took quite a few minutes to recognize it. I haven't tried it but there seems to be empty ram bays as a well.

I'm currently using this stand with a E/Port Replicator Docking Station PR03X. It's hard to make sense of all of the Dell product numbers, but this appears to be the same as or at least a version of the PW380.

there is a VGA port and 2 HDMI ports, and I counted at least 4 on the back and 4 on the front 2.0 USB ports, as far as 3.0 I do not know hope this helps

This is the original R1. I believe the R2 is a recent addition. The R2 has a window and appears to have more USB3's on the front.
