Hello, I fryed my usb connection, by connecting to a bad usb port. The usb still work for UMS and transers, but now the dap puts itself in usb charging mode even when not connected.
On the iriver firmware it works fine until I try to shut it down. It then goes to sub charging.
This is why I switched to rockbox, but since recent versions, I can't switchoff the H340, probably because rockbox changed the usb handeling.
If you could help to detect what changed since it could help me to do custom builds.
Could it be related to the bootloader ?
