Hi, there exists two proposed patches out of USB/PCI issues in OpenWrt CC (and still DD)... arch/mips/include/asm/io.h: https://dev.openwrt.org/attachment/ticket/20997/0400-fix-IO_SPACE_LIMIT-constant.patch arch/mips/lantiq/irq.c: https://dev.openwrt.org/attachment/ticket/21318/0401-fix-irq-chip-for-exins.patch Unluckily I'm not the author. So it would be great if someone could adopt these to get some more devices working properly (again). Kind regards gh
