    My computer, like most, has a whole bunch of USB ports on the back, and a couple on the front. They have all got something plugged in... printer, keyboard, mouse etc...one of them has my wireless broadband connection gadget... Every now and then, Windows (XP) pops up a messagbox saying: This device can perform faster...will function at reduced speed when plugged into a non-HI-SPEED port. It then lists all my port for me, telling me to plug it into a HI-SPEED one, which it tells me are listed in bold: + SS PC to USB Enhanced Host Controller   + USB Root Hub (8 ports)     D-Link AirPlus G DWL-G122 Wireless USB Adapter(rev.C)       Unused port       Unused port       Unused port       Unused port       Unused port       Unused port       Unused port What the b*h* is it going on about?

      It means you plugged a USB 2.0 (high speed) device into a USB 1.0 (low speed) port.

        I know it's saying that, but not why is it saying it.. All the ports listed are the 8 that belonging to the "USB Root Hub (8 ports)", which is Hi-Speed. And why is it telling me that 7 of them are unused when they are not? Or have I got the wrong end of a big stick here? (I don't understand hardware...) Ta...

          For some reason, the driver doesn't think they're high speed ports. Perhaps you're missing an update to the chipset drivers for your motherboard??

            another posibility would be that he has a usb2 hub plugged into a usb1 port on his mobo.

            -- You have to explain to them [VB coders] what you mean by "typed". their first response is likely to be something like, "Of course my code is typed. Do you think i magically project it onto the screen with the power of my mind?" --- John Simmons / outlaw programmer

              True. Maybe even the other way around too.
