Any computer gurus out there with solid knowledge willing to try and tell me if my laptop is fried? Had power surge & lost usb ports - but they still have power. Will charge cell phone. 2 of the ports are on a separate board with cable going to mother board. Have replaced the separate board with the 2 ports, updated bios, wiped hard drive and did fresh OS install, removed the coin shaped battery off MB, uninstalled all USB devices and had system reinstall at start up, but none of this has worked. Still have an "unknown device" it says in device manager. Is controller/controllers on the MB? Is something on MB fried? There is one of the intel chips or host controllers in device manager that says it doesn't have drivers. Tried to locate drivers for it off intel site with no luck. Machine has had recent upgrades, runs good, so hate to chunk it if USB ports can be fixed with some type of software/driver fix. If something on MB fried, then will chunk it. Any suggestions from any PC geeks out there greatly appreciated. Thx!

What brand computer? Sound like you would need what is known as a chipset driver.
Have you right clicked the device and select "allow windows to search internet for driver"?

says no driver for this chipset - but go to update then say already has most current or correct one. No errors showing under USB devices now - as mentioned before i have uninstalled all USB device and rebooted PC several times.Attached FilesComment

I realize it's now a cheap machine, but so am I, and don't wanna chunk it if can be fixed with a driver/software fix as everything else works good. Thx so much Jfisher for your input..Comment

Checked support.dell.com? Should be a section where you enter the Dell service tag number to locate the devices original configured drivers. Or use their system detect download utilty.Originally posted by budrow View Post
If you haven't already, maybe set the bios to defaults.
Also just occurred to me... boot into safe mode and look for and remove any duplicate usb or controller related items in device manager.... might even be worth removing any instances, restart and let plug and play rediscover them.Last edited by 47; 09-02-2017, 11:39 PM.Comment

From what you've described it sounds an awful lot like a driver issue. The easiest way to tell if it's a driver issue or hardware issue would be to boot to a linux live distro. Download and boot to Ubuntu live, if the USB works in Ubuntu its a driver issue, if it doesn't it's likely hardware related.Comment

Good idea. Considering it's a Dell, could also boot to bios(F2) or the diagnostics, see if mouse working there.Originally posted by cfortner View PostComment
