Hi,

On the Pandora, we used a sneaky way to test both USB Ports as well as the SD Card slot at once:

We switched the SD Cart slot into mass storage mode (using g_file_storage). Then we used a USB cable to connect the USB OTG port to the USB Host port and mounted the SD Card slot as external mass storage device and copied a file.

I'd like to do the same on the Pyra but am running into some issues.

I know g_file_storage has been replaced by g_mass_storage.

But when I run modprobe g_mass_storage file=/dev/mmcblk5

I get the output: couldn't find an available UDC

mmcblk5 is the inserted sd card (I can mount the partitions on there).

Anyone has any ideas what's missing?
