How to connect a external CD drive to iPad Pro
Is it possible
Due to power requirements by CD or DVD Drive normally it wont support iPad Pro USB C port. iPad still limits the output power that accessories can draw when connected. If the CD Drive has dedicated powersource, then you may try connecting and see if that works or not bro.
Before purchasing any CD Drive its recommended to try once at nearest laptop pc sales showrooms. They have such portable usb a drives or usb c drives for OS formatting and installation purposes.
