I bought this laptop (Acer Aspire 9525WSHi model: MS2196), 2 months ago. It has 4 usb ports. One on the right is working fine. But 3 on the left side are not detecting anything. I did not instal any driver or program at all. I tried to solve problem by restoring the system to factory default using erecovery. But usb still not working. I believe they never worked, and this fault came inherent, with this machine. The device manager shows, that all usb hubs are working fine.
I tried many devices like phone, memory stick, camera etc, but these 3 usbs do not detect anything.

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
hi, yes it is a motherboard issue-i have 2 of those with same problem. new boards for that model are costly. however i found a work around-get a usb pcmcia card put it in the slot on the side-then plug your mouse or other usb devices and you should be ok! I did this a year ago and it runs like new! way cheaper than getting a new one. this is a big problem with these 5100 models. acer no help-other than selling you a new mainboard. this is the best way 2 make it work again. the pcmcia cards are cheap enough. and after that you can get a usb hub if you need more ports. good luck! and please rate this solution. and make sure 2 turn on the cardbus if not on allready. (in epower manager) this will work! reply if you need help! be well!
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.
Is there any possibility that they could have been inavertently turned off in the bios? Forgive me if this has already been addressed...but if you have not checked it, reply to me and I can walk you through it.
