Problems getting the ft9201-fingerprint-driver to work

[joonas-foo]

Hi, I'm having problems using the driver, I'm a novice Linux user, here's some info about it:

Were you able to make and install the driver? My device ended up being /dev/fpreader1. What do you get from: ls /dev/fp Do you see an ft9201 module loaded? e.g. lsmod | grep ft

Hi, In my case the driver is installed although I've a warning with make: warning: the compiler differs from the one used to build the kernel

And when I install the driver, 'System.map' is skipped.

I run "sudo depmod -a" after installing it, but it does not return anything.

In my case, I can't list /dev/fpreader0 or /dev/fpreader1, neither when I search for the module.d.

$ make ft9201_util 
make: 'ft9201_util' is up to date.
$ ./ft9201_util /dev/fpreader0
