Not sure. If you don't have it then it is probably easiest grabbing a more recent pre-built kernel from your distribution. I suspect that SuSE has somewhere for getting 'leading edge' kernels. 'hid-lg4ff' was improved by Michal back in August to include support for all Logitech wheel and run them in the native mode (to get 900' rotation etc). A change log is here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=history;f=drivers/hid/hid-lg4ff.c;h=6ecc9e2204409c1451e90086a4edd7f0639cdb01;hb=ccb19d263fd1c9e34948e2158c53eacbff369344 Simon
