Saluti alla lista. Ho appena acquistato una fotocamera digitale Canon Powershot s10, a detta dei man supportatissima dal pinguino e gphoto2 in particolare.Non appena la connetto alla porta USB usbview mi segnala la presenza correttamente, ma i vari tools di Kde (Kamera, Digikam) mi rispondono "Could not claim the USB device" per quanto l'icona appaia. Gtkam(e conseguentemente anche Gimp;-( ) risponde "Could not initialize camera". Come ROOT mi ha dato la conferma della fotocamera "inizializzata", ma i vari tools (scusate, ma con le foto DEVO lavorare in ambiente grafico!) rispondono sempre quanto detto sopra!

Scusate la patafiata;-), ma mi sembra una corretta esposizione! Domanda: Sicuramente il problema è una cosa minima e fastidiosa come una zanzara in campeggio;-/! Ma dov'è? Qualcuno l'ha già risolto o visto la soluzione di altri? ps: ho letto vari blog.. dall'italiano al tedesco ma niente! Grazie tantissimo, Alberto pps: ODIO dover usare M$ per la grafica! -- Per iscriversi (o disiscriversi), basta spedire un messaggio con OGGETTO "subscribe" (o "unsubscribe") a mailto:linuxtrent-request@xxxxxxxxxxxxx
