[linux] InfraRed recording device configuration

[Geert Stappers]

Hoi,

Hopelijk heeft iemand van jullie ooit met Infra Rood "opname aparatuur"
gewerkt.  En kan me verder helpen.

Mijn hardware zou Dangerous Prototypes USB IR Toy compatible moeten
zijn.

Met `dmesg` zie ik o.a.
[167075.854629] usb 1-1: new full-speed USB device number 8 using xhci_hcd
[167076.009564] usb 1-1: New USB device found, idVendor=04d8, idProduct=fd08, bcdDevice= 0.02
[167076.009577] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[167076.009582] usb 1-1: Product: USB Infrared Transceiver
[167076.009586] usb 1-1: Manufacturer: Irdroid 
[167076.009589] usb 1-1: SerialNumber: 00000002
[167076.013070] cdc_acm 1-1:1.0: ttyACM0: USB ACM device

`lsusb`:
Bus 001 Device 008: ID 04d8:fd08 Microchip Technology, Inc. USB Infrared Transceiver


In de manual page van `irrecord`:
       -d --device=device
              Read from given device. Use mode2(1) --list-devices to list available devices for a driver.

Echter `mode2 --list-devices` geeft geen output.

Hoe computer "laptop" te configureren voor de aanwezige hardware?


Ik hoop op een bericht als
  "Je moet bestand ..... hebben."
om van daar uit verder te kunnen zoeken.
