USB extender
I have 6 USB ports on my Dell 2400(desktop), but want a few more. Actually, I mainly want one or two near me so that I can change a few flash drives, my cell phone and my camera. (I have my PC mounted to the wall -- it's accessible, but a little inconvenient).
I got a 4 port extender from Wally world, but I thought I'd ask here before I opened it up. As I recall, USB supports a lot of ports, but I wondered how that worked out in practice. Does adding extra ports noticeably slow things down? Most of the time, the added ports won't be doing much, but I don't know if just having them affects the overhead.
Thanks,

each device has a unique id that registeres with the OS when it is plugged in.
there is some speed associated with the level of usb you have. so if you put in a USB disk drive, and a USB cd rom, and copy form one to another, both devices are sharing the 'channel' so the overall speed of the USB connection is at least halved.
another item is power - some devices get all power from the USB port so most good extenders block current and have their own power supply and just supply a high impedance signal in case the OS or the device needs an edge to trigger something.

It has been my experience by adding a 7 port 'hub', I have easy access to the USB connectors.
My old desktop PC only has two USB ports on the back.
I put the 'hub' on the side of my desk, where it's easy to reach.
I also put a 'mini-hub' on my wife's laptop.
The USB ports (2) on her laptop are behind a door on the back edge.
I placed the 'mini-hub' on the back of the screen (lid) with industrial strength velcro.
As for any slowdown. . . I haven't noticed any loss in speed for practical applications.
(I mean, I can't go make a sandwich and grab a coke while moving files from one flash drive to another!)

If you had enough splitters and extenders, each USB port on your computer can actually support upto 127 devices. If your USB ports are USB 2.0 (they should be) you should be able to connect a few data intensive things without performance suffering to much, it is not like you'll be transfering data off all 4 thigns are the same time anyways
