If I use two ports will the device connected be slower than if I were using just one?

Nope, I've used all 4 at the same time and everything works perfectly still.

I have never run into any noticeable speed issues with this USB hub. If you have two or more devices plugged into a USB port through this or any USB hub, AND if both those devices were transferring data at the same time, the technically speed would be compromised. In most cases, though I think this would be true even if you were not using the hub, but just plugging multiple devices into multiple USB ports on a computer. All communications ultimately has to "fit" onto a single communications bus in the computer.

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.

Yes, you can connect two of them, it should not matter but I would not run both at the same time.

No. Not at all. I use it at work and I'm using all 4 ports with no problems.

A splitter will not allow the device to have enough power. The device will work on one port but at reduced power. Davids' suggestion is your solution.

Quite a bit, actually. I use one onboard USB port for WiFi and the second for a 4-port hub that contains mouse, keyboard and flash drive. One free. No problem.

I have noticed that it works just as fast but not any faster than the other ports.

I don't think so. It sends only one of your input connections to the output.

No, the most you get from each individual port is 2.4 amps. Or the 4.2 amps using both at the same time.

It isnt anything special. Just make sure you get a mini usb to 2 regular usb cable. (Yes, that is one end is a MINI USB (not micro) and then the other end will have 2 regular sized USBs.) It is because one pulls power and the other actually send/receives the data IIRC

I am not sure, but if you couldn´t just plug both ports, it probably means it isn´t possible, since there is a single "on" switch...

If it is a self powered hub--Yes. If it is powered from the computer and is trying to charge multiple devices at the same time--No or it might charge very slowly.

No, only one device at a time. The first one to connect stays connected until you turn either device off.

Not sure. I used one end to connect to an ac adapter and the other to transfer data, but it didn't work, it didn't generate enough power. So, I'm thinking depending on the device, probably not. Hope this helps

It only uses 1 port, but I opted to use a Logitech performance mouse and keyboard. For me, I desired a larger mouse and smaller keyboard. They work great!

I don't know the exact number but I have successfully connected 3 devices. Jus keep in mind the more device you connect you may have reduced speed.

Yes, it works great. It does need to use two use ports however. I do not leave it connected and have only for when needed.

If you are using a low-power USB connection then the second cable provides additional power. You probably won't need to use it.
