thanks for that - along with your dmesg output from the vendor kernel
this gives us some more details
your dmesg indicates that SDIO port/slot 0 is used for the wifi chip,
see all these aml_sdio_print_err messages with "pdata->port=0"
it also confirms that GPIOAO_6 and GPIOX_11 are used to power on the
wifi chip and that GPIOX_10 is used as pin for the LPO (32.768 kHz)
unfortunately the kernel log when booting my kernel does not show
anything about the wifi chip.
I would have either expected error messages from mmc0 or a short
message that the device was detected.
can you please show me the output of /sys/kernel/debug/mmc[0-2]/* with
my kernel and the original Android/LibreELEC kernel?
regarding your USB problem: unfortunately there doesn't seem to be
anything relevant in the Android/LibreELEC kernel logs.
can you please provide a patch with the .dts changes you made so I can
have a look at these (maybe there's a typo somewhere)?
