Interface stopped working - audio / midi / data from USB stick.
USBC port problem
I normally connect my iPad Pro 12.9 to my Roland DuoCapture to record mic, line audio and midi signals through the USBC Port
The interface midi audio signals will connect correctly to my iPhone.
The interface cable has been replaced.
The USBC port will correctly connect to charge the battery.
noted upper right hand usb icon is present for about 7 seconds and disappears
I recently updated to 16.3 iOS. How can I roll back the iOS?
iPad Pro, iPadOS 16
