Users with an older PC with USB 1.1 ports will have to buy a 2.0 add-on upgrade card to be able to hook up 2.0 peripherals. True / False?

    No, backwards USB compatibility works both ways.The 2.0 device will operate on a 1.1 USB port at that ports defined bandwidth. The result will be lower performance for the device if it demands more bandwidth than the port can supply. Generally video, HD printers, high bandwidth drives will suffer performance loss. Mice, keyboards and other low demand devices see no change no matter what gen USB used due to their minimal bandwidth requirements. Consult the device manual for more information.

    no. the 2.0 spec mandated backward compatibility. but you'd need to upgrade to take advantage of USB 2.0 speeds.

    Most (not all) 2.0 devices will run on a 1.1 port.  they will just be limited to slower speed of the 1.1 port.  Which for some devices will make them impractical to use.  Same is true for using a 3.0 device on a 2.0 or 1.1 port.

    Those that will not work on the 1.1 port are usually not because the port is not able to communicate with the device.  It is because the manufacturer did not write the drivers needed for the device work properly to run with a 1.1 port.

      i don't even think that would present a driver issue other than outdated OS drivers. i think the spec mandated that all drivers be backward comparable anyway. although there's a good chance a compy with usb 1.1 is so old it's running XP or earlier and may have zero compatible drivers.

    The specification for all USB ports is that they are backwards compatible with every previous versions of USB. If you use a USB 1.1 to a USB 2 port converter it will not give you any benefits whatsoever. Every converter ever made are a ripoff for those who don't know computers. Stay away from them

    That's true if you want to be able to use a USB 2 or USB 3 device you're going to need both the operating system to support it and the hardware to support it.

    To use 2.0 peripherals, FALSE. 2.0 devices will throttle down to 1.1 speeds and work just fine. You do not need a 2.0 card to use 2.0 devices.

    To use 2.0 devices at full speeds, TRUE, as you cannot get 2.0 speeds with a 1.1 interface.

    That all said, most 2.0 devices do not run at full 2.0 speeds, and using them on 1.1 ports may be only a bit slower. Most PCs will warn you that the USB device can perform faster is you use a 1.1 port with a 2.0 device, but that is just a warning.

    You can use them and hook them up but your speed of transfer will be less than 2 can provide.

    Yes and no, the old ports do not work properly with many devices from ten years ago, or even longer. They fit, look like they are working and then you will be disappointed. However, brand new generic items such as joysticks, keyboards and a mouse should be OK without having to upgrade if you still want to use an old computer for some reason.

    Who comes out with rubbish like this (and then asks in Anonymous mode!) No, no, no. 2.0 peripherals were backwards compatible!  I'll be anonymous like you!

    USB connections on a PC are backwards compatible so the answer is false.
