My usb and usb c have stopped recognising my samsung ssb external hard drive. Works fine on my laptop. When plugging in my phone it says on the phone " not enough power" it worked fine before for transfering files. Have tried resetting the cmos with pin but no difference..

And you could try to do the steps below to see if that could work.
1. Find "Computer" on the computer desktop, select "Manage", and then click "Device Manager" to open the Device Manager.
2. After entering the device Manager, find the Universal Serial Bus Controller in the device Manager.
3. Double-click any USB Root Hub. The USB Root Hub Properties page is displayed.
4. Find the "Power Management" TAB, remove the check mark in front of the "Allow computer to shut down this device to save power" function under this TAB, and then click "OK" to save the Settings.

Hope it helps, Have a nice day!
