Well, that was easy

I think ethernet switch and wireless aren't supported by opensource drivers so even with OpenWrt booting on Huawei B593u-12 it's not much use. USB connected LTE module is not detected, my guess is that some GPIO needs to be toggled to enable it. PCA9555 GPIO expander would need some work too. Also 256MB NAND-flash is missing, only 16MB SPI flash is found.
