I have a ACER travelmate 661LMi with a build-in 4p-USB hub + USB card reader The USB ports seem to work fine when i use a mouse or a keyboard or even a GPS receiver. BUT only when I plug-in a USB mass storage device like a external card-reader, USB memory stick or a digital camera windows keeps refreshing te connection like in; ON OFF ON OFF ON OFF ON OFF ON OFF ... DRIVE F:\ .. NO drive .. DRIVE F:\ .. no drive .. DRIVE F:\ .. no drive etc.... It just freaks me out! I have tried everything, drivers, firmware .. really everything. I clamed that it is the windows USB power management that is not working properly Please HELP!!
