Well I got a new Multifunction printer-copier-scanner..it's a Canon PIXMA MP 500. The copying on the flat bed is INCREDIBLY slow.
I keep getting a pop-up that says "the USB Composite Device will function at reduced speed. You must add a Hi Speed USB controller to obtain max performance."
I checked my computer and it shows 2 controllers and 4 USB ports (I only see 2 in the back and 1 in the front).
I would check to make sure the USB cable you are using is a USB 2.0 cable and not a 1.0
Is this computer new (after april 2000)?
as found on a website...
"For the most part, the High Speed USB controller will be integrated right onto the motherboard of your system. You will sometimes run into this problem when upgrading to or installing a new version of XP, for sometimes it does not readily have the drivers available. What you have to do is to actually find out the motherboard that you have in your system, and download, or request the CD, that has the motherboard resources on it, in order to get Windows to install that particular controller. If you have a name brand computer, you should be able to contact the manufacturer to get the CD or download. However, if you have built the system, or someone else has built you the system, you will need the CD that came with the motherboard."
If the compueter is older
"Older computers often do not have high-speed USB controllers. However, you can purchase these as PCI cards at any computer store. Shut the computer down and open up the computer's case. Next, slide the USB card into a free PCI slot on the computer's motherboard. Start the computer up and XP should detect the new controller. Insert any driver CD provided only if asked by XP - most don't require it."
One way to determine if you have USB 2.0: -Right click My Computer on your desktop -Select properties -Click the hardware tab -Click the Device Manager button -Expand Universal Serial Bus controllers -Look for an item the says something like "USB2 Enhanced Host Controller"
Have you installed all of the windows updates? I think there was a patch for USB 2.0 on some devices.
If you don't have USB 2.0 an addon PCI card with a couple of ports is cheap.
I have a Dell-got in 2002 I don't want to get a new computer because I added memory (now 768 MB Ram), a 2nd hard drive, plus all my "stuff" is on here. The thought of moving all my software is daunting.
The controllers listed in device manager are: Intel 82801BA/BAM USB Universal Host Controller 2442 the 2nd one is the same except ends with 2444
As long as I can add a Hi Speed controller it will be OK.
[invalid URL removed]The 82801BA/M is only USB 1.1. But it looks like it supports PCI Rev. 2.2, so you should have no problems just getting a cheap USB 2.0 PCI card.
If it had been a little older (PCI Rev 2.1) you'd have had to read the specs for the cards carefully first.

You need a Phillips screwdriver and a minute or two to do this, seriously. It would take the shop longer to generate a receipt than to do the actual work.
Open case, pick an empty PCI slot, remove the one screw holding the corresponding slot cover in place on the back of the case, slip out the slot cover, plug the card into the slot, put the screw back in (now holding your new USB card in place), and close the case back up. Done. Windows will auto-detect and set the thing up when you turn the machine back on.
If you're going to do it yourself don't forget to turn it off, unplug the power and wait a minute for the capacitors. Also make sure the card is seated properly (you won't be able to screw it in if it isn't)
after the install go to windows update and install all the critical, optional and hardware updates. Then run it again until no more updates appear.
There is no difference between a USB 1 cable and a USB 2 cable. Using the same cable was a key design goal in USB 2, in order to minimize end-user confusion.
There was a few companies that sell a premium-priced line of cables stamped “USB 2!” but that's just marketing poo.
To be safe I'd get more. you only need hi speed ports for anything moving a lot of data like mp3 players, digital cameras, web cams and printers... etc. you can use your old ports for your keyboard and mouse or disable them in the bios.
They have some listed as 4+1. the +1 is a port on the card that is only intended to be connected to a front panel connector inside of your PC. Sometimes in order to use the +1 port you have to disable or avoid using a port on the back of the card.
