Has anyone found a good USB drive solution for lightning port iPads?
USB support is one of the main things I was excited about with iPadOS but the lack of power being outputted from lightning is making it difficult to find any storage accessories that work without external power.
I have tried using a micro-sd car in an adapter like [this one](https://www.amazon.co.uk/Kingston-FCR-MRG2-Generation-microSD-Reader-Black/dp/B0028R3NCU/ref=sr_1_37?keywords=kingston+micro+sd&qid=1570783071&s=electronics&sr=1-37) and while it worked for a minute it is extremely temperamental and often stops working, saying “The operation couldn’t be completed. Bad file descriptor”
Has anyone out there with a lightning iPad figured out a reliable way of using USB storage with iPad?
