Question about Toshiba Satellite A135-S2276 Notebook
After resetting bios on toshiba a135 the port usb not working e shown "Usb device not recognized" for any device (pen, printer )
Bios version: 1.4
If you open Device Manager, do you see exclamation marks or red "x" sings on it or question marks from the USB Host Controllers? If yes, what is the error code? It helps if you post the error codes. If it doesn't have any, the IRQ of those USB ports have been changed by the BIOS update and you may need to downgrade BIOS. Only Authorized Service Providers by the way have the tools to downgrade BIOS.
Try running Everest. You can get it here. it usually identify devices even without drivers loaded then we can start from there to what drivers we need to install
Hope this helps
