AudioMoth not recognised on iPad Pro with USB C connector

When trying to view the output from an AudioMoth USBmicrophone with the OxfordWaveResearch Spectrum View App on an iPad Pro tablet the AudiuoMoth is not recognised by the tablet when connected via the USB C socket with an Apple "USB C to USB" adapter. The iPad/SpectrumView App does recognise a Dodotronic Ultramic 250K connected via the same adapter.

However, the AudioMoth (and Dodotronic Ultramic 250K) is recognised by an iPhone X running the SpectrumView App with an Apple "USB to Lightning" adapter ?

Is this a known problem ?

Hi, indeed I am mystified !!!!!

and again yes, I have been perturbed a few times with forgetting to switch to 'CUSTOM' etc !

I will let you know if an alternative extension cable works ????????

Thanks for your, as always, very prompt help and advice !

Replying to

ADDITIONAL INFORMATION !

It seems the"AudioMoth USB mic" IS recognised if a SHORT i.e. 1 Metre, micro-USB to USB-C cable with Apple USB-A to USB-c adapter is used !!!!!! But NOT with some longer cables, I have tried 5 metre or 9 metre cables !
