USB Hubs.

OK, another dumb question from me.

Need to replace my old 1.1 USB Hub to USB 2.

There seems to be two types, the ones with a separate Power Supply and ones which are BUS powered. I'm , what are the practical differences ?

As I don't need to power anything from the Hub except for Storage Devices do I really need one with an External PSU ?

It depends in the usage. I could be wrong with my numbers here but a bus powered hub draws its power from the port its connected to so only has 500mA, it can use up to 100mA its self so can only power devices that use 100mA or less (based on a 4 port hub).

This is fine for most devices but devices that use a lot of power might not work on the bus powered one. (main example would be a 2.5" external hard drive that doesn't have a separate power supply)

A powered hub gives the whole 500mA for every port.

So really depends on what its for.

apologies of my numbers are out, i'm sure I'll be corrected if i'm wrong, this is all from memory.

its all fun until something falls off.

All sounds very reasonable, thanks.

I hadn't thought about the total capacity of the four Ports being limited to the total of 500mA from the USB slot on the PC but of course that's correct.

Even though I don't plan on plugging anything into the Hub except for USB Pens/SD Cards I'm now thinking that an externally powered Hub may be the best option.

Didn't know there was such a thing ! Can't see it working for me as the PC only has USB 2, I think, so unless the USB 3 Hub is a magic box of beans don't think it's going to work for me !

Other problems today with my BB connection. The BT Home Hub 2 has been very temperamental the last few days, very slow, and I mean very slow, less than 100KBS. Put my old Router back on this morning and now at about 2.8 MBS which is about right for me.

I can feel a long distance 'phone call coming along although I know it's not really going to help. I'm really sick of what seems to be almost constant problems with the BB.

2 port USB 3 if you want to add via a PCI Express card
4 port USB 3 if 2 aren't enough...
4 port USB 3 hub, needs single USB 3 port which wouldn't work as intended for you without one of the above.

Those look good but a bit complicated for me ! Just looking for one that plugs into one of the PC USB Ports and gives me the extra sockets. ( Like a Mains Extension Lead thing as in your third Link but without having to get into the PC. )

Fair enough... That said, the inside of a PC isn't as mystical as some would think... I built my first one without hiccup, no manual and very little idea what I was doing at the time.

Likely scenario...
1) Undo 2 screws and remove side
2) Undo screw and/or remove blanking plate by relevant slot
3) Push card into slot
4) Replace screw
5) Replace side and screws

Done.

Maybe add software if disc needed (always do before you put the side back on and it will work, else it will fail )

In this case I'm sure you'll find a sufficient USB2 one though... I should stop digressing and stick to the original problem lol

Nige, if you go down the bx mod route make sure is switched off but leave it plugged in to the mains with the mains switched off to earth the pc.

What's up Zed ?

Even my old USB 1.1 Hub works well enough for most things. It would be a bit slow if I wanted to Download lots of stuff from it but on a day to day basis it's OK for me.

My " new " PC has USB 2 Ports so I thought that upgrading the Hub may be a good idea.

I then found out, thanks to the good folk above, that USB 3 is now available !

What to do, what to do !
