(A1619) Apple USB Camera Adapter (USB3) Firmware Update 1.0.5 removed functionality?
After the Firmware 1.0.5 update the adapter stopped recognizing ALL of my USB flash-drives.
Yes, it is powered through the lightning port on the adapter.
iPhone SE 2020 running 14.3 (MXVA2LL/A)
iPad Mini 4 running 14.3 (NK9N2LL/A)
I just bought the thing today and used it for a few hours. Now it's worthless.
