yes, I fixed one bug that has killed remote. Now it works again.

Probably there is wrong ir-table loaded to the device by the driver. 
Ir-table in device and ir-codes from remote should match. Otherwise it 
will not work.

Yes, thats correct. AF9015 implements also HID-remote but I have never 
got it working. I think it could be due to hw bug. Luckily there is 
other way to read remote - polling from the driver.

I just tested using...

1)
[root at localhost ~]# hexdump -v -e '"\t" "0x" 1/1 "%02x " "\n"' < 
/dev/input/by-path/pci-1-5--event-ir

2)
[root at localhost ~]# av7110_evtest /dev/input/by-path/pci-1-5--event-ir
Input driver version is 1.0.0
Input device ID: bus 0x3 vendor 0x15a4 product 0x9016 version 0x200
Input device name: "IR-receiver inside an USB DVB receiver"

Remember that the HID one does not work at all.
