|It has only appeared in the last couple of months. I've had the computer for years. The message appears every time I switch on - or even wake the computer up from sleep mode.|
The message is "This device can perform faster if you connect it to a Hi-Speed USB 2.0 port." It then tells me a list of available ports: "Intel (R) N10/CH7 Family USB2 Enhanced Host Controller - 27CC", with under that "USB Root Hub (8 ports)". The 8 ports listed underneath are all unused. There are only 3 physical USB ports that I can see.
LATER EDIT: OK, I've found a difference between 27CC and the other 4 hubs listed by Device manager (all 5 are said to be working correctly). 27CC is working at "high power" but the other 4 are working at "full power". So I guess the message is telling me to switch 27CC to "full power". However, when I click the button on the 27CC page (Advanced, under Properties) to "Reset Hub", nothing happens (I was hoping to be offered the choice of "high" or "full" speed.
As my question is now a different one (how to reset a hub) I'll regard this exchange as closed - thank you for your effort to help. I've opened a new question about resetting hubs.
