All the USB ports of my Dell Inspiron 17R, 5720 are not working. When I connect a USB drive I hear the 'connected sound,' the light in the USB flashes red to show it is connected but no USB drive logo appears in My Computer.
I have tried multiple thumb drives, cell phone, tablet and also updated BIOS, Chipset and all USB drivers but the problem persists.
I have also tried the following:
- Uninstalled all my drivers and restarted.
- Tried the Dell Forum and got no help.
- Tried the Dell Diagnostic Software and gave USB Test. I am unable to complete the test. ( I passed the general test)
- I tinkered few things and had a USB 3.0 External HD work in one of the slots yet USB 2.0 flash drives did not work in the same slot. Hoping to make the USB 2.0 work, I tinkered once again and now USB 3.0 also no longer works.
Screenshot of my Device Manager is attached.
Thanks in advance for the help and time!
