According to some technical bumpff I've read recently, there are several typers of USB: USB2.0 and 'high-power' USB.

To charge my appliance, I require 'high-power' USB as, seemingly, my two USB ports are basic 2.0 connections to which the peripheral does not respond in an uncharged state.

So, is there anywhere I can acquire 'high-power' USB (Maplin?), and can this USB plug into my normal USB if you see what I mean, ie there should be no need to insert an independant high-power USB card?

Thanks again, this probably makes sense only to the techie fraternity! !wink!

Not specifically heard of High Power USB but assume it can supply more power than USB 1.0, 1.1 & 2.0 can deliver
Hence expect you will need either a PCI card in the PC or a hub (box that splits out a USB socket in to several) with a power supply built in / lump in cord / plugtop PSU to supply the extra juice.

Try a 'Y' cable - 2 USB into one.

High power USB simply means it draws more power than a standard keyboard, mouse etc.

I use one with an external USB drive - works a treat where it didn't before.

My understanding is that "high-power" means the device needs more power than can be drawn from the computer via USB. So you need a USB hub with its own power supply.
Don't want to seem picky but there's an aweful lot of info. out there if you Google.

Yes Mart - and a 'Y' cable doubles the available power.....

Thanks all.

I tend to post here as a first port of call on techie issues- you tend to get a succinct answer quickly, and to the point.

If it is not resolved, I do a Google- and sift through the crap until I get the appropriate info!

As you have said, I think I will get a 'Y' attachment with an on-line power supply. I never realised that the triviality of the USB had variations! But then, on thinking about it, one wonders how the more power-intensive appliances (high-spec scanners etc) would get by on USB alone with no independent power source.

You learn something new every day?
