USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2.
Way 1. Check your connectivity
Check the USB port you have been connecting your drive to. If the port is damaged the drive won’t show on your Mac computer. If you are not so sure of the functionality of the port, do a further evaluation to be sure. One way to evaluate further is to try the drive on another port. If the second port does not work, try it on another Mac computer device. If it shows on the other device then it means that the ports on the previous Mac computer are damaged. If it doesn’t show, try the next fix option.
Way 2. Check Power
It is possible that your flash drive is not showing on your Mac because of insufficient power. Power shortages or fluctuations occur if you are using a hub to connect your flash to the computer. A perfect solution to this is to connect the flash drive directly to the computer instead.
Way 3. Failure to eject Drive before
One reason why your Mac may not be showing can be because you failed to properly eject it when it was connected to your computer. A forceful pull out of the drive can damage it. Avoid doing this to your drive. If you must eject it, do it the proper way by requesting for a safe ejection and only eject when Mac gives you the go-ahead.
Way 4. Update Firmware and OS
Updating your Firmware and operating system fixes a lot of functionality issues both in your internal and external drives. If you are experiencing a USB not showing a problem, a quick update may fix the problem of the flash if it is corrupted.
