Hi julspower
Quote
what gets created when I put my other dongle in?
Possibly a driver that the non-working one needs? Try running:
Code: [Select]
lsmod > badmouse.txtwith it not working. Then plug in the other dongle so the mouse works and run:
Code: [Select]
lsmod > goodmouse.txtCompare the two files to see if anything new was loaded.

thanks for pointing that
evdev wasn't loaded when its not working
If I get a console in ssh and I modprobe evdev everything is fine
A possible workaround is make it load with the .xsession script

Code: [Select]
sudo modprobe evdev
Enables the K400 keyboard and trackpad in the PiCore GUI, however, despite:

filetool.sh -b

does not survive reboot. To overcome the reboot hurdle add the instruction:

Code: [Select]
echo "sudo modprobe evdev" >> /opt/bootlocal.sh
save the instruction to survive reboot:

Code: [Select]
filetool.sh -b

That's because you can't backup the memory that a driver was loaded into. The  filetool.sh  command only backs up files. I don't think
a driver that you  modprobe  manually would survive a reboot in any Linux.
