Didn't see a thread on 52, but installed it on my new n900. (First one would not recognize sim card anymore, and used various kernel-power versions with no problem). I noticed the camera would not work, the notification led would not work, nor the keyboard lights. I did an apt-get for the fcam drivers, but no effect.

I installed the original kernel, and the camera and led would work, but not the keyboard.

I tried to install an earlier version of kernel-power, but it would not download.

Installed v52 again, and same result.

Installed the original again, now I am stuck in a reboot loop.

I am also getting this from the flasher: Suitalble USB device not found, waiting

Any help would be appreciated.
