  middi 22:32 26 May 2003

I would like to buy a Canon LiDE 30 scanner,would someone please explain what USB 2 means. I am a novice user and have only basic knowledge, thanks.

USB 2 is a later and faster version of USB. If your PC is fairly new you may have USB 2. If you have the older version it will still work, although not quite as fast.

USB 2 is the connection that will be used to connect up your computer to your scanner.

The "2" just means that it is the faster connection that USB can give you.

There is/was USB 1.1 which is slower and now there is USB 2 which is faster.

You can connect a USB2 device to a USB 1.1 connector on your computer the only difference is that it will not work as fast.

You need a USB port on your computer to connect up your scanner. Look on the back of your computer for a rectangular connection.

What operating system do you have - USB is only really supported from Win98 up (and before the whining starts WiIn95 OSR2.5 but it's crap)

click here check the specifications for LiDE20 and LiDE30 both say USB interface. The LiDE50 says USB2.

I know the 20 is 1.1 and the 50 is 2.0 Not sure about the 30, but I think that from the specification it is also 1.1 Regards. J.

Think we haven't really answered your question - USB1.0 & 1.1 transmit data at 12mbs whereas USB2.0 transmits at 480mbs. USB2.0 is backward compatible - as mentioned USB1.0 & 1.1 devices will still work in a USB2.0 slot

Will USB 2 work properly on Win 98SE? as I remember someone saying "Nay"

  Djohn 01:44 27 May 2003

Yes it will, you need to buy a USB2 PCI card, this can be a 2 port or 4 port, and start from approx. £20.00.

Easy to fit, just slots into one of your spare PCI slots inside at the rear of PC, no drivers required, automatically recognised by 98se. Once fitted, just plug in any USB hardware, that also includes USB1.1 Regards. J.

Thanks for that Djohn and glad you got sorted Middi.

It'll only work as USB1, I read. Also, wasn't there an issue re terminology eg "high speed"?
