Thanks @oouzoo - that download fixed the Gemalto card reader for iPortal for Barclays too.

even with "Allow accessories to connect" set to any option in the dropdown, it doesnt work still.

"Allow accessories to connect to Mac" is only an option on LAPTOPs and not iMac or Mac Studio :-( https://support.apple.com/en-nz/guide/mac-help/mchlf779ae93/14.0/mac/14.0

unfortunately it has not fixed it for me. Was your latest an upgrade or a clean install?
