There is no driver required for a USB Floppy drive. The USB driver is part of the Windows OS.
Are you using this on a Laptop or a Desktop? If a Desktop, be sure to plug it into the Back USB port of the computer and not the front because those ports are weaker.
With the drive plugged in, it should be listed as an A: Drive in File (Windows) Explorer.
If not, press the Windows key +X and choose Device Manager.
If there are any devices with a Yellow mark, Right click it and Uninstall it. Remove the USB cable for the drive and restart the computer.
Open File Explorer, and plug in the USB cable, you should see the A: drive pop up.
If the drive is not reading your disks, then they are probably old and corrupted.

 

I plugged into the rear of the PC. (Thanks for the tip). At first a message said, 'Please insert disk', then quickly shifted to 'Location not available'.

 

This is a little tricky. So, first Remove the USB cable from the back USB port.
In the Device Manager, right click any device and choose Scan for Hardware Changes. Nothing will change, this just refreshes the list.
Now Insert a disk into the drive, Open File Explorer, insert the USB Cable to the Back USB port, In File Explorer, you will see the A: drive for just a second or two, Click on it. You have to be quick and you may have to do this a few times to get it right, If you aren't quick enough, the A: drive will disappear. After this, the A: drive should always be there unless you unplug it.

 

Hi
I did exactly as you advised, but no luck.

 

Try the drive on another computer. Be sure to plug it into the Back USB port, not the front or thru a USB Hub as these ports are weaker.

 

Hi

I plugged into rear of another Computer.
A:\ is not accessible.
The request is not supported.

 

I hope you have a Known Good Floppy Disk inside the drive when you try to access the A: Drive? Try several disks
If they all fail and you know the disks work, then there may be a hardware problem with the drive

I tried a different brand of Floppy Disk, I can read the documents.

This means Driver is OK, problem was the Disk.

Thank you.
