Check that device manager recognizes the device with no errors or warnings.
Put a known good device in that port...process of elimination!
Check that the usb device is functional in the Device Manager, Some USB devices don't appear in Device Manager use the utility program that came bundled with the device to check for errors. No. Plug the device into another USB port. If it does not work after you have plugged it into all USB ports on the computer then you know that your device is not working.
One of the simplest ways is to use USB flesh drive, keyboard or mouse. Just connect to the port in question and try to use the device. If it works then the port is OK, otherwise you have found the port (or one of them) causing the problem.
To determine what is tripping your circuit breaker, you can unplug all devices on that circuit and then plug them back in one by one to identify the culprit. If the breaker trips when a specific device is plugged in, that device may be causing the issue.
First try moving the device to another USB port!!! Check that the usb device is functional in the Device Manager. some USB devices don't appear in Device Manager use the utility program that came bundled with the device to check for errors.
Check it on another computer first. See if it's seen but not installed correctly. If you insert the device and there is no reaction from the device manager then perhaps there is an issue with the hardware. Otherwise it's likely a software problem on the system in question.
A fuse is the simplest protective device for over current in an electric circuit.
Plug two or three devices into that port if none of them work the port is defective.
I would remove the usb device and see if the problem goes away, if it doesn't you will need to open the computer. Once inside, you will see a serial wire coming from the suspected usb port to the motherboard, go to the motherboard and disconnect this jack. Hopefully your problem will go away, there may be a short in the port itself causing too much electrical current in the motherboard.

To determine the memory size of a device, you can calculate it by multiplying the number of memory cells by the size of each memory cell. This will give you the total memory size of the device.
