| 14871 | 2001-07-02 22:22:00 | I have been looking around for a USB hub and note that there are powered and unpowered models available apparently both running at the same transfer speeds. Could some advise me what the difference is between these. Other than the price - the unpowered ones are half the price! | Guest (0) | ||

I would go for the powered as in the future there will be more powered appliances which use the usb port for power as well as communication. (Side point wait for USB2) |

| 14873 | 2001-07-04 00:03:00 | Some USB devices require power and some don't. If the USB port is not powered then any USB peripheral needing power fails to work. e.g. I have several Windows machines and an iMac. The iMac mouse is USB an plugs into the keyboard which also plugs via USB into computer. But an external USB floppy drive plugged into keyboard USB failed as it needed power. A powered hub allows both powered and non-powered devices. Non-powered USB hub only allows non-powered USB devices I |
