Hi there, during the last 2 weeks, all my usb ports on the laptop are not working. first it was just the 2 at the back of the laptop, then the 3rd one went a couple of days ago, i am at my wits end trying to sort this out, i have tried to find a solution online, nothing concrete as yet. i have had the laptop for 14 months and it is running windows vista. i have checked the usb controllers and hubs on the device manager, they're shown to be all working properly. i have also tried to uninstall and install the drivers but nothing! please help!

Check your device manager for the imaging device ( webcam )
If not found, try booting into safe mode and give a look again in device manager.
If you have any usb devices connected disconnect them
If all of this do not work, you may have disconnected the webcam or could be bad.
hello, this has been one of the most reported problem with the 5100 model. i have 2 of them, and they have done the same thing! one i had 2 find and install a new mainboard-400 bucks! not very cost friendly. i did post a solution more than a year ago, but it is a work around that let me use the acer with the dead keyboard,touchpad,usb- you must buy a pcmcia usb card, it goes in the slot on the left side of the acer 5100. then a usb mouse and keyboard will work. (you can get this cardbus adapter cheap, as 400 bucks is 2 much. these pcmcia cardbus card come with 2 or 4 ports. this will let you use the pc, it has been a great solution for me and a lot of others, been in use over a year like this. acer is no help, unless you wish 2 spend a large amount of $. the one with the new board lasted about 8 months before the usb port stopped working for the second time, i then got a second cardbus usb card and have usb again. sorry for your problem.. good luck! do as i say and the acer will work again.( a problem model) just search for pcmcia usb cardbus you will find many 2 choose from- i picked the ones with the NEC chipset, as these are reliable! be well!
Try using external USB HUB (POWERED) Adapter. It might fix this issue. Use an other USB cable and see. If the problem still exist do not plug in the printer again, you may damage your USB port or even burn your laptop motherboard. hope this helped
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.
Hard power-off (hold the power button until the laptop turns off) Unplug the AC adaptor Remove the battery Plug in the AC adaptor Hold ctrl and turn the power on. You should arrive at a black screen. Hard power-off again, then turn the power on.
