You would need a power source for the drive. the usb pro allows you to connect the dvd drive to the computer using a usb port (rather than a sata connection). You could use the xbox but that could be kinda sketchy, I personally use the CK3 pro.
So you would need a power source (ck3 pro/ck3i etc), the usb360 pro, and possibly a probe depending on the drive to flash. And jungle flasher

good luck
