I even checked whether ---usb is enabled in CMOS setup i found USB controller blank ,there is no option present to enable or disable. what might be the problem.... ?...(i got my bios flashed a month ago with latestest BIOS update),is it problem with OS or Bios thnx nikhil
If you are positive that USB is enabled in your CMOS setup, then you have a problem with Windows. Go My Computer > Control Panel > Add Hardware. Let the computer detect your USB hubs/controllers. Report back
hi You got me wrong ! i went to cimos setup to see if usb is enabled or disablebled.... the usb controller under cimos is blank there are no options present to enable it or disable ........what might be the problem...
There are no options whatsoever in the CMOS? Can you see any options that might have been grayed out for example? Have you run the 'Add hardware' wizard yet?
Well! I have a website but I am not sure it is trustfull or not Code: http://driveragent.com/?ref=71 According to this website, they will scan your computer and update the drivers~!.........
usb section is simply blank in CIMOS(not even in grey mode) usb was working fine until before i flashed my BIOS... ...is this the problem
Your saying that as soon as you flashed your BIOS, the USB stopped working? Could you see USB settings with the old BIOS/CMOS setup? In that case, then you can only point your finger at the BIOS. Are you certain you flashed the correct BIOS utility? If you made a backup of your previous BIOS, then I recommend that you restore it. Failing that, go back onto your manufacturer's website, download the latest (and compatible) BIOS, and reflash your BIOS. There's an old saying "If it ain't broke, don't fix it"! Did you really need to flash your BIOS in the first place? If anything goes wrong with the BIOS, your computer is essentially :swear:
You must have flashed it to the newer version and if its not working then it means you have done smthing wrong~! Do what megamaced is suggesting you~!.......... From where did you flashed your BIOS actually?
Seem quite obvious but are the pen's USB and the mobo's USB compatable? i.e. if the pen is USB 2.0 and the mobo is 1.1 it is no good.. etc... you catch my drift
It supports but the only damn problem you will come across is the speed of data transfer. USB1.1 port will not give you the full efficency of USB2.0.........
