I have an acer aspire 5100-3577 notebook. none of the usb ports work anymore. i have made system restore, deleted infcache.1 , deinstalled and reinstalled the drivers and the usb ports. the drivers are the latest ones available and the devices are working correctly according to the device manager. any memory stick, cameras, printers etc. connected are working on other laptops or computers but not on this one.

Re: acer notebook usb not recognized
Sounds like a hardware issue. I would guess that there is a bad connection between the usb's and the motherboard. If you are comfortable dismanteling the laptop and re-soldering the usb's than give that a try, but I would recomend you give it to a pro.

If none of your USB ports work, there could be a problem with your USB controllers. Uninstall the USB controllers via Control Panel - System ... and reboot your laptop. They will reinstall upon bootup. Good luck.
hi there , hey have you went to the bios setup and checked the setting for the usb port and made sure that they were inabled and checked device manager and looked for view and than selected devices by connection and seen if there were any problems and you can also use the system restore if all fails and see what that gets you ok please let me know there still is a lot of things that can be tried but see if any of these will help
best regards mike
I think the root issue of usb ports not working is a problem with your USB port's drivers no longer communicating with your computer. This often occurs when you install an update to your computer's operating system.
I hope i can help resolve your problem for you.
this may be a problem relating to your system device driver files.
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.
Two solutions would be to either restore your pc to before the problem started,using system restore on accesories menu, or use the recovery cd or the recovery folder Acer laptops usually have on the 'D' drive and re-install usb controllers and drivers.
