Explanation

If the laptop does not detect the USB device at all, the most likely cause is that the USB port has been disabled - either in the BIOS/UEFI settings or via OS-level group policy. Administrators sometimes disable ports as a security measure. Anti-malware (B) might block execution of malicious content from a USB drive, but it would not prevent the device from being detected. Insufficient memory (C) affects application performance but not hardware detection. Account permissions (D) may restrict what a user can do with a detected device, but they would not prevent the OS from recognizing that a device was plugged in.
