Hello,
There are two physical USB port on the pi zero+ board : one is USB 2.0 host and the the second one is USB 2.0 OTG through a micro USB connector. As I power the card through the expansion pin I would like to turn the micro USB to a regular mode to connect a DVB dongle.
With Armbian 5.38 and Kernel 4.14.14 (and also nightly build) I've done the following modification
- in armbian-config enable usbhost0
- modify the /boot/dtb/allwiner/sun50i-h5-orangepi-zero-plus.dtb
=> decompile the file with dtc
=> edit the dts file and change the line dr_mode = "peripheral" to "host"
=> recompile the file and reboot
After reboot when I dmesg | grep usb0 I've got the message [ 2.207647] usb0-vbus: disabling
Is there any solution ?
