text: i have hap ominbook 4150  laptop.6yrs old downloaded win xp sp.how do i get usb port to work now? i had xp (sp2 ) put on my old 6 yr old hp ominbook 4150. it had windows 98 before.. but after putting on xp home. my usb port (only one) doesn't work . i tried contacting microsoft site.. they told me to try this and try that .still nothing. i haven't got the the windows 98 cd...never had one..or i would put it back.. also haven'y got the xp one eirther... it there someplace i can get a free copy of either or how do i fix my poblem?? first you should check in your bios.  it is possible that since the machine had win98 originally that the bios never had usb support turned on.  if that is not the case then check with hp's site to see if there is an update to your existing bios.  this might have the patch needed to activate you usb.  it sounds more like it is turned off in the bios though.
