There is something I don't understand about the lirc_zilog drivers. I have HVR-1950 and I have been successful compiling the patched drivers. However, the drivers cannot find my device. Please find an output of dmesg:

root@mythtv:~# dmesg | grep lirc

Could someone suggest why the driver fail to see the device?
BTW, I am using the latest pvrusb2 drivers.
OS is Mythbuntu 9.10 kernel 2.6.31-16-generic
