Questo e' il classico argomento che ti fa odiare Linux ed in particolare Debian
Mi e' stato regalato il ricevitore infrarosso HP ed il relativo telecomando in fotografia. Connessi ad un computer con XP entrambi sono stati riconosciuti senza problemi senza la necessita' di installare driver
Connessa la porta usb del ricevitore la risposta in dmesg e' la seguente

--------------------------------------
Come si vede chiaramente (anche dalla foto) il dispositivo e' compatibile con Windows Media Center (MCE)
Per controllare il dispositivo sotto Linux e' necessario installare il software lirc per cui mi sono attrezzato con
apt-get install lirc
il demone pero' non riesce a partire e la soluzione e' abbastanza banale.Se si guarda nella directory /etc/lirc/ si puo' vedere che tutti i file di configurazione sono vuoti per cui ho cercato su Internet le corrette configurazioni sulla base delle informazioni ricavate dai log
alla fine il demone insiste a non partire e la soluzione e' ancora una volta chiara
il file di configurazione richiede il modulo mceusb2 ma digitando da linea di comando
modprobe mceusb2
il modulo non viene trovato
sono ripartito quindi da capo rimuovendo il pacchetto deb di lirc
apt-get remove lirc
e scaricando da internet il sorgente di
lirc
in fase di ./configure viene richiesta la presenza libusb-dev per cui ho aggiunto
apt-get install libusb-dev
lanciando ./configure appare la seguente finestra (puo' essere necessario prima fare
apt-get install dialog) e si deve selezionare nessun driver
a questo punto si puo' terminare la compilazione secondo il classico configure/make/make install
la novita' e' che il modulo mceusb e' presente e lanciando il demone
/etc/init.d/lirc start
il comando va a buon fine
i file di configurazione sono
hardware.conf

lanciando il comando ir-keytable si ottiene che il ricevitore e' su /dev/input/event12
-------------------------------------------------------------------
Found /sys/class/rc/rc0/ (/dev/input/event12) with:
Driver mceusb, table rc-rc6-mce
Supported protocols: NEC RC-5 RC-6 JVC SONY LIRC other

a questo punto si lancia

per controllare che tutto e' andato a buon fine ho quindi lanciato il comando

ottenendo come risposta
