Is it possible to turn off a specific USB port so it doesn't accept any device?
I have a lot of ports on my computer. I would like to turn off one of them, so when I connect my phone to that port, it only charges. I do want my phone to work with my computer in some occasions though, so I hope other ports are not affected.
I would just like to know how possible this is.

Possible.. But some hacks are needed to do this..

Hardware solution: Buy a male to female USB plug and cut/isolate/remove the center lines.

First, run lsusb.
The output should be like:
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 2232:1020
Bus 002 Device 009: ID 0bc2:a013 Seagate RSS LLC
Bus 002 Device 003: ID 0a5c:219c Broadcom Corp.
In the output, find the device number of the port to be disabled. For example, the Seagate drive in the example has Device 009 - that is its device number. Then the id will be usb[device number] - such as usb9
Then, disable USB wake-up (do this only once):
Be sure to replace X in usbX with the device number.
echo disabled | sudo tee /sys/bus/usb/devices/usbX/power/wakeup
Then turn it off:
echo suspend | sudo tee /sys/bus/usb/devices/usbX/power/level
Undo this:
echo enabled | sudo tee /sys/bus/usb/devices/usbX/power/wakeup
echo on | sudo tee /sys/bus/usb/devices/usbX/power/level
