Hmmm. Which driver? I don't see any switch-related driver, nor any
userspace (what I have is an extremely minimal OpenWRT userspace that
has hardly more than busybox).

This is all I see:

root at OpenWrt:/# find /sys -name registers
/sys/kernel/debug/usb/ohci/0000:00:0e.1/registers
/sys/kernel/debug/usb/ohci/0000:00:0e.0/registers
/sys/kernel/debug/regmap/dummy-bus at c4000000/registers

Thanks,

	M.
