Powered usb versus other usb I keep asking questions and really appreciate this forum...it is well supported and fast moving! Another question...what is the difference between the powered usb and the other usb? I tend to use the one on the right for transferring files and programs but that I think is the "unpowered" usb.

Both USB ports are the same expect if you use the hp multi-bay. one has extra 5volt power. I would explain more but a picture is worth a thousand words...

Two comments, it i may:
1. Powered USB means, it can provide more juice for power-hungry devices - instead of usual 2,5W it gives up to sth like 20W - the extra power is needed for devices such as CD burners.
2. The extra PIN on the connector is... just a piece of metal that is only a mechanical thingy that protects you from connecting the MultiBay Cradle to non-powered port. You can use standard USB cable to connect the cradle and it will still work fine with powered USB port.

because of "powered" usb ports, I now can charge my cell phone, and GPS with the same cable from my laptop w/o having to carry chargers for everything... I also have an external DVD burner that takes power from the USB and I also have a small USB powered hub, that let me and son share a wired ethernet plug, so we can both be online in a hotel room...I don't think any laptops have been made in the last year that aren't powered

Thanks for the info, I never really understood how it worked. Every one I asked including our HP rep said "adds extra power" but no details.Originally Posted by jakubd
I often get asked this at work. now I can give a better answer than "adds more power"
Thank you.
