USB Hubs

I've just bought a powered 7 position USB Hub,but I notice that my Broadband Modem and my Zip Drive (outside) will only work when plugged directly into one of the USB slots on the computer.
Are there USB slots and USB slots, with some working for some add-ons and not for others?

I haven't look into it, but as I understand it, there is another USB slot called USB2, I know if this USB2 is taking over from the normal USB. Don't know how it works. Sorry.

as said above, my guess is that it has a fault. i run 8 things from two belkin hubs and they all work ace.

You have USB1.0 and USB 2.0 and these only really denote the transfer speeds of each. I don't have the figures to hand but I am sure someone else will. Have you tried connecting the Hub to other USB ports on your PC?

Recently I installed a new Lexmark X5150 printer and a Umax scanner into my system.The scanner would not work, so I contacted Umax for advice. They stated that I would need a self powered Hub.I purchased the hub, connected the scanner,and all worked okay.Running short of direct USB connections, I connected the Lexmark printer to the self powered hub. This method did not work, as the printer at certain stages, caused the computer to crash, so I contacted Lexmark. Their advice, was that I had to connect direct to the computer hub, and not via the self powered USB hub.So two different pieces of kit, with different working methods.

The amount of current your computer can supply through its USB ports is finite and connecting peripherals that require, or combine to require, a heavier current than your computer is designed to provide to USB can cause malfunction by:
1. Causing the peripheral to malfunction
2. Cause all attached peripherals to malfunction
3. Cause your computer to crash or shut down
Using a powered USB hub, regardless of whether it is for USB 1.1 or USB 2.0, provides the current the attached peripheral requires without taking it from your PC.
Occasionally you will get a funny where a peripheral will only work properly when directly connected to the computer USB port but it is ideal to attempt connection through a powered hub first.
I have USB 1.1 and USB 2.0 both operating powered hubs and have no problems, the only peripheral connected directly being my ADSL USB modem.
I had a problem with the first powered hub I used and tried it on another computer and found the same faults. My retailer replaced it and it has worked fine since.
