Why Vista does not support USB1.1 based CD-ROM simulation? RRS feed

  • Question

  • I have a USB Flash disk that is USB1.1 based, it has an AutoRun feature that can autoplay a software while plug into WindowsXP PC.


    But after migrate to Windows Vista, this feature is unable to use.


    How come? any ideas or help?

  • I know that sometimes its a hardware issue that limits to USB2.0 only. Go into BIOS and see if there is a option to turn on legacy USB1.0

  • The site I found out about WHS from had a bit of info that might be helpful. I'm not on the computer i found the info on, so I can't link it atm, but it said no USB 1.x support on WHS.


    Now, I can't vouch that its true, but thats what I read.

  • NO, USB 1.1 devices will work with WHS: you probably installed using a USB keyboard or mouse.

    However, USB 1.1 mass storage devices will slow Drive Extender to a crawl. So using USB 1.1 drives is an "unsupported" scenario, in that Microsoft neither tests nor tries to accommodate the scenario.
