if you have it working I would not do a factory reset of the iOS device. It seems that has not been addressed yet. Good to hear that restore to iOS 11.0.2 via iTunes gets it working again.

I had similar experience. To fix it (at least for me in this instance), I had to plug in the iXpand USB drive, and then reboot my iPad (Off and On). Only then would it recognize the Ixpand USB drive had been plugged in... and all worked as expected.

if you do upgrade it will take about 30 seconds to recognize the ixpand. from the reports of beta tests with iOS 11.1 the 30 second detections issue seems to be fixed.
also do not reset the phone after updating to iOS 11. if the phone is reset no storage devices will be detected.
