Since I "upgraded" to Windows 10 Anniversary, connecting my reliable old MP3 player results in
It didn't happen before and still works fine on non-upgraded Win10 machines. The device, as far as I know, appears as a class-compliant disk, so uses the built-in Microsoft driver. Device Manager seems to think that the device is working correctly.
One difference I do see between the updated and non-updated machines is in the driver version: Anniversary Update shows 2006-06-21, v10.0.14393.0, whereas my non-updated laptop reports the same date but v10.0.10586.0
How can I persuade my updated PC to recognise my device before Microsoft force-updates everything and I lose the ability to connect?
