I am trying to get my new receiver to recognise music files on a USB flash drive. I have tried Media Player and i-tunes formats without any luck. Then I found buried in the manual a little note that said I can only use Sony Microvault USB devices - specifically the model number USMnGL or USMnGLX. Since both of these products appear to be obsolete now, I bought a USM32R. Still no luck. Any ideas what to try next?
