If you plug in a mixture of USB 2 & 3 devices on this hub, will ALL ports default to the lowest speed (USB 2) or not ?

I have not tried to test this, but it does not appear to default to USB 2. I have my trackball/mouse and two USB 3 ext drives plugged in and the hard drives are as fast as ever when backing up files to them.

It'll just be the USB 2.0 device that runs at the 2.0 speed. Your 3.0 devices will still run at 3.0 speeds. BUT take note of any bottleknecks! If your computer doesn't support 3.0 or you don't use a 3.0 port, you will not get 3.0 speeds! Also, something like transferring a file from a 2.0 ext HDD to a 3.0 ext HDD will only operate at 2.0 speeds max.

You will have 3.0 speed from 3.0 ports, and 2.0 speed from 2.0 ports. 3.0 board does not use 2.0 USB portions of motherboard, it connects directly to communication bus of motherboard.

In short, no. USB as a protocol supports far more devices through a single port than you can physically put on this hub. And, because of how the data is packaged and transmitted, it all moves at the same speed, regardless of the number of sources. For example, I have 3 devices (a wireless mouse, a printer and an external HardDrive) running through mine, and they all perform perfectly.

No. All the USB 3.0 share the same bus at 2.5Gbps. The ports controlled by a singe 4 ports Fresco Logic FL-1100 USB 3 controller.

You don't have to use both of the USB ports, I only use the one. The thought is the secondond USB cable will increase the speed but honestly I haven't noticed any marked increase

No. Connecting a 2.0 to 3.0 in any direction will always result in the lower speed of the two. However, they ARE compatible with each other, but you can only get a maximum of USB 2.0 out of this particular reader.

I haven't noticed any decrease in performance between the powered 3.0 drive and the 2.0 flash drives I have plugged into this hub. They work at their rated speed for the most part. For the most part the computer's controller chip and the device controller work those issues out unless there bad programming involved

Do you have other devices using the other ports at the same time? There is only so much power that the USB port can pull from a single USB 2.0 and 3.0 at a time.

I am using the device with an older desktop with USB 2.0 with all ports utilized (including two back up drives, keyboard, mouse and phone charger) and I have never had any such issue.

My assumption is yes, only because this is the first USB 3 card that I bought that REALLY gives me USB 3 speeds. Be careful purchasing hubs though. Cheaper isn't always better.

I use mine as an extender from my PC to a 2.0 hub. All 2.0 devices connected share the same bandwidth. If you have a 1.1 device it will still operate but all devices will see decreased speed and performance. Best to connect direct to a PC and replace any 1.1 cables.

Yes, I use it for both USB 3 and 2 and it works fine. But it is a lot slower with 2.0.

Yes, it works fine in USB 2.0 ports, usually faster than a 2.0 flash drive in the same port. You won't get the screaming speeds of a 3.0 flash drive in a 3.0 port, but it's definitely an improvement over the 2.0 flash drive.

Yes, but I noticed no performance gain in 2-in, 2-out mode over USB 2.0. Worked great in both USB 2.0 and 3.0 ports

I plugged in a crappy USB 2.0 key to test this - an old Verbatim that I would swear is slower than a floppy drive. It didn't slow down the read/writes on my super speedy USB3 Patriot Magnum at all. So, no, USB 2 devices won't slow down USB 3 devices.

Just note that USB 3 ports of this docking station run at 2.5Gbps/sec (not at 5Gbps/sec). This only becomes a limiting factor if you connect an SSD thorough them. For other stuff 2.5Gbps are more than enough.
