Akhil Kapoor: > Thanks for the info but the setup works with windows. It's still a *potential* solution. Power through USB is supposed to be software controlled. According to the specifications, only a low level of power is supplied by default, and higher levels must be negotiated. If there's a USB driving issue with your hardware, the negotiation mayn't be working. It's not unknown that some things seemed to work with broken implementations of USB on Windows, that happens to match also broken designs of USB devices, but the same devices wouldn't work on something else (not Windows) that used USB properly. I read about this with USB-powered external disc drives, if I remember correctly. An external powered hub can supply power to USB-powered devices in a different manner than the motherboard might. And can help deal with devices that demand more power than they should from USB ports. I can recall other tales about some USB-powered scanners being less than reliable on Windows, but quite fine when powered alternatively. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
