I'm not posting this as an answer because I don't know exactly what was the problem that made Bitdefender affect the USB drivers. Okay, as another user recommended, I tried uninstalling Bitdefender and the problem went away. I started seeing that Bitdefender was blocking a "virus" identified as Gen:Variant.Tedy.68373 from the temp folder, but that started happening yesterday. Right-click each USB port, then click 'Enable.' If this does not re-enable the USB ports, right-click each again and select 'Uninstall.

Click 'Universal Serial Bus controllers' to see a list of USB ports on the computer. What could be causing this and what could I do to solve it? Click the Start button and type 'device manager' or 'devmgmt. These USB devices work every time in other computers. The mouse and a USB keyboard still work, but not the storage devices. I used to use a USB hub and connect all the USB devices to it, and realized a Samsung SSD and another Flash drive weren't working, but a wireless mouse was. This started happening last week, and I haven't installed anything new I sort the installed apps by date and I can't see anything recently installed. If I want a USB device to work, I have to restart the computer. I've tried updating the drivers, uninstalling the device (Storage controllers and Universal Serial Bus controllers) and rebooting, shutting down while holding Shift, updated the BIOS, found available Windows updates and installed them, used USB Oblivion to do a cleanup, and cleaned the registry with CCleaner, but nothing works. I've looked all around, and tried several things, but nothing fixes the issue. This doesn't happen the first time I connect the devices after a startup, but once I disconnect them and connect them back, I can't see them and get this error. The driver could not be loaded because a previous version of the driver is still in memory.
