USB ports and devices make connecting to another computing
device convenient.
USB technology has been around since 1996, and is a feature
found on most modern computing devices.
If your device is denied access to one of its USB features,
do some troubleshooting to isolate and resolve the problem.
Viruses
Some computers come with a security feature that
automatically denies access to a USB device, such as a flash drive, if harmful
content is detected.
Installing an anti-virus software application and regularly
scanning the computer and any connected USB devices can help you avoid experiencing
denied access to a USB device.
Avoid opening USB flash drive files that you cannot identify
or do not recognize, as these types of files are how viruses find their way
onto unprotected computers.
Incompatibility
Inserting an incompatible device into your computer's USB
port can also cause you to be denied access to your device's USB features.
For instance, if your computer supports USB 1.0 technology
and you insert a USB 2.0 or USB 3.0 connector, the computer can experience
interfacing problems that may cause a "USB access denied" prompt or
situation.
If other USB devices begin to malfunction after inserting an
incompatible USB cable into your computer, turning the computer off and back on
again may resolve the situation.
Formatting
USB flash drives, also known as pen or thumb drives, are
among the most common types of USB devices used in conjunction with computers.
Most USB flash drives are formatted using one of three types
of formatting methods: FAT16, FAT32 or NTFS.
If you've formatted a USB flash drive using one method, used
it on the computer and then reformatted the drive using another method, you can
be denied access to the flash drive through the computer's USB port.
Wiping the flash drive clean and reformatting it again can
resolve this type of problem.
Considerations
Many computer accessories, including printers and pointing
devices, connect through the machine's USB ports and can interface
interchangeably with multiple computing devices.
This feature increases the risks of picking up viruses and
experiencing unauthorized reformatting. Limiting the amount of computers your
USB devices accesses can help you avoid these situations.
Damaged USB cables can also make it impossible to access USB
devices when they are connected to your computer.
USB cable damage usually occurs at the points where the
cable and its connectors meet. Replace any damaged USB cables.

values on any hard drive on your computer.
