Thanks for replying,balbes150. Appreciate that.
As for the armbian.txt file, all i did was just input my SSID, enable wifi/ethernet etc.
Anyway, did tried with several dtb files today.
While the rest of dtb files hanged at the armlogic logo upon power on the box,
i only managed to boot up from the generic dtb (gxbb_p201) till the armbian logon screen.
Yet again, there's no response from the keyboard when trying to input the password.
Any other way or method for me to get the usb ports working and detect the keyboard?
Or could there be any other armbian image available that able to auto detect usb device?
