Adding formats (mp3/mp4) in user defined usb driver plugin
Hello,
I also manage mp4 and mp3 files in calibre. I want to send them to an usb device.
When I try to send the file to the usb device I get an error message that no suitable format was found. I also cannot select mp4/mp3 when I want to send a file in a specific format (mp4/mp3) to the usb device.
In the configuration of the user defined usb driver plugin mp4/mp3 is not available for selection.
How can I send mp4/mp3 files to the usb device respectively how can I add mp4 and mp3 to the format list of the user defined usb driver plugin?
Thanks in advance, Steve.
