USB file transfer speed is extremely slow/low, how to fix?

"Does anyone know how to fix low data transfer speed from a USB flash drive? I got an extremely slow USB transfer speed when I tried to transfer files from my computer to the USB drive.

It was about 2GB of files, and I’ve got some data saved on the USB drive. Then I connected the USB drive (about 20GB of free space left) to my computer and started transferring files to USB. I waited for 2hours, but the transferring process was still at 15%. This was too slow. 
So I stopped the progress and tried again. Still, the same transferring speed on the USB drive. So how to make the file transferring speed faster? If you know the way, please let me know. Thank you
