USB-C Hub No Longer Recognized by 2021 iPad Pro 12.9" on iOS 15

I have the NGE 11-in-1 USB-C to HDMI Multiport Adapter Dongle. It worked with my 2021 iPad Pro earlier this year. When I plugged it in last night, it no longer seems to be recognized by the iPad.


More information

  • The iPad isn't recognizing devices and drives plugged into the hub.
  • The devices I was trying to use (Yamaha EAD-10, Sandisk 32GB Flash Drive, MIDI to USB) all worked previously this year (September 18 was the last date that I can confirm it worked. MIDI to USB) without additional power being supplied to the hub.
  • The iPad is still providing power to the hub, and the hub is still able to pass through power to the iPad when using the hub's USB-C power passthrough port.
  • I tested the hub this morning on my Macbook Pro and it is functioning correctly.


I am curious if the iOS 15 update might have caused this hub to no longer be supported on my iPad. I did not update to iOS 15 until the first half of October 2021.


iPad Pro, iPadOS 15

Firstly, iPadOS 15.1 is current. If you have not already updated to this version, you should update; this version includes both functional enhancements and essential security patches. Perform the update without you Hub being connected to the iPad.


As for the specific issue that you describe, I use a similar USB-C hub on a daily basis. I have not encountered any issues with connection of peripheral devices via the connected USB-C hub - either with or without a Power Adapter connected to the USB PD pass-through power connection.


As such, whilst your Hub appears to be working with your Mac, perhaps you have a problem with your hub. Substitution of a different hub, ideally certified to be compatible with iPad, is advisable.
