Likelyhood is when kernel got upgraded, modules moved from /lib/modules to /usr/lib/modules and this module was in extramodules
If you move it to the new place and run depmod -a it should work (reboot then may be required)

You're absolutely correct, thanks.
Moving to /usr/lib/modules/extramodules-3.1.9--raspberrypi does allow the module to be found.
depmod -a OK
but when I do modprobe 8192cu there's a error, "could not insert 8192cu": Exec format error

There is version magic with the module, it doesn't match kernel version, tried to make rebuild easy on the rpi, it takes 10 minutes to do
Code: Select all
wget http://myplugbox.com/rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622.tar.gz
tar xzf rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622.tar.gz
nano Makefile

Change KVER to what the current version is (there must be a way of automating, but feeling lazy)
It's currently set to-
KVER := 3.1.9-31-ARCH+
Code: Select all
make
cp 8192cu.ko /usr/lib/modules/extramodules-3.1.9--raspberrypi/
depmod -a
modprobe 8192cu
