It may be coincidental, but I bought a memory stick off ebay which turned out to be fake. Since that time, I found that every time I turn on my Acer Aspire laptop it will not recognize anything (stick, drive, camera, ipod etc.) plugged into the USB ports or a card in the memory card socket.
No messages or anything, just no reaction to anything plugged in.
DeviceManager shows nearly all the ports (Intel ICH9 Family USB Standard and Enhanced Controllers) and the USB Root Hub(s) with little yellow exclamation marks.
At first I uninstalled all the hubs manually and restarted the computer and this got the hubs working, but next time I booted up, the same thing had happened and I had to go through the whole thing again.
I then found that the Troubleshooter and Windows Fix It (ha ha
) would reinstall all the hubs automatically, but they would still be corrupted next time I booted up, so I had to go through the whole rigmarole again to use the USB ports.
Each time i use the Troubleshooter it fixes all the ports, but I get a message - "Hardware changes might not have been recognised" and a yellow warning triangle.
Fix It does exactly the same with nothing else to offer regarding the "Hardware changes...." message.
Next time I start the computer I am back to square one!
I have tried updating the drivers
- I always get told they are up to date.
My computer OS is totally up to date with "Windows Update".
I always remove the USB devices properly.
Another post elsewhere suggested checking that the Windows Installer in Services is set to Automatic - it is.
How do I get it to recognize the hardware changes so that it starts up with all the ports working every time?
