I am happy with my hub. I use a IOGEAR 2.0 usb and card reader hub. Works really well, It looks nice, has 6 usb ports with it and 4 different types of card readers.

My father had usb ports on his keyboard, which when ever used, kept saying it did not have enough power. So I will be planning on getting him a usb hub sometime in the future.

Thanks for the great videos Chris (like always) I found this information very helpful on some problems I have seen having with my Belkin USB Hub. It turns out that the hub not my computer was causing thre conflict between iTunes and my iPhone. I guess my hub is not USB 2.0 :(

Still covering the basics, please correct me in anything that I’m wrong, cause I’m in no way an expert:

- The plugs (interface, for geeks) are the same in any version of USB so far. The differences lie in the motherboard and in the software (drivers).

- There are slightly different USB cables that, for what I know, borrow their name from the odd end. That’s because one end is always USB as usual, and the other can be another USB plug, a mini-USB plug (I usually see them in phones and cameras) and something I call micro-USB (because I don’t know the name), which I’ve seen in memory card readers.

- I’ve seen systems in which the USB drivers can be upgraded. I’m not sure what the requisites are, but the PC came with USB 1.1 drivers installed and we could upgrade them to 2.0 without opening the box. It was mostly a matter of uninstalling the 1.1, checking something at the BIOS and then installing the 2.0 — much faster — drivers. I’m not saying this is applicable for anyone. It might just be applicable to a particular user that wants it upgraded.

USB 2.0 is backward compatable with USB 1.1 which means that a USB 1.1 device will work on a USB 2.0 hub.

An additional consideration when attaching a USB device to a hub is the amount of power that the device requires. A hub that does not have it’s own power supply may not have enough power to run the device.

I just wish some of the USB wireless adapters, USB wireless mouse dongles, and other USB devices were designed a little less “high profile” i.e. didn’t stick out so far.

Like for laptops – you have this nice portable computer, slim and sleek, not tethered to anything via any cords.

You plug a USB dongle into it and now you have an awkward piece of electronics sticking out the side or back, ready to catch on something and break.

Now you should talk about firewire!

Wow. So long as the Motherboards have the ability to keep up with USB 3.0, I would be damn tempted to get a 3.0 external HDD and use that instead of the internal one.

Firewire 800 is way more than 2 times faster than USB. Just because USB runs at 480mb that is theoretical. It never reaches the maximum because it ponces off the system whereas FW has a dedicated controller. Firewire 400 is way faster than USB 2 even though USB 2 can theoretically reach 480mb. Firewire3200 (the next version) runs at 3200mb, whereas USB 3 runs at 4800, however I bet you whatever you like Firewire 3200 will totally smoke it. In fact I cant see USB 3 being faster than FW800 tbh.
