I assume you have the v4l-cx23885-avcore-01.fw file available for the cx25840 module, just so there is no problem initializing the CX23885 AV core. 2. Does dmesg or the logs show the input device being created? Somewhere in the log you should see: "cx23885 IR (TeVii S470)" when the input device is created. 3. With the "debug=7" option to the cx23885 module, do you see any IR interrupts coming in? In dmesg or the log you should see: "(PCI_MSK_IR 0x...)" when an IR interrupt happens. Tonight I will: a. Add a guess at HVR-1800 support so maybe Steve can help us debug as well. I know the NEC decoder works; I tested it. What I don't know is if the CX23885 AV IR implementation works (I don't have CX23885 hardware at the moment). b. Add a temporary patch to add a /dev/videoN node for the TeVii S470 so you can use "v4l2-ctl --log-status" to show the status of the IR controller and v4l2-dbg to dump the cx23885 and cx23885-av-core registers, so I can see if everthying is set right. c. Review the register settings to make sure interrupts should be enabled for the IR controller.
