I can only get my 2 front USB ports to work if i put a drive into both of then at once then turn the Audya on. it will only show the contents of USB-2 and the drive in USB-1 shows its empty even though i know there are files in it. anybody had the same problem

How big is your stick?
I also have problems with more than 4 - 8 GB.
Sometimes these are not loaded.
Better to always use the smallest size.
I switch on my Audya4, wait until everything is loaded, then I only put on the USB stick.
I recognize it from the LED from the stick, if it flashes after plugging in, it also works.

it is recommended no more than a 16gb usb drive.
is there a 2GB drive available.
At the moment I switch on the Audya and if I insert USB drive into US1i or USB2 nothing happens

Sorry, i have 4 - 8 GB Sticks

But I also have problems with larger sticks,
are sometimes not recognized.
I then format the stick with FAT32
Copy my data and then it usually works.
I recognize this by the flashing light from the stick.
If only it shines, it doesn't work either.
Maybe you should make a reset once.

I found the PC board (PB453} the 2 USBs sit on is malfunctioning.
Hope AJ can get me a new one.
If in the end the problem is not in the PB453 board it will be down in the main CPU board.
