[Tech] realizzazione driver

[raphael calvelli]

Ho una macchinina digitale, che non ha il driver usb sopportato, e 
l'azienda mi dice che hanno il driver solo per windows;

Il mio linux riconosce il tipo di macchinina, ma "unhandled device";

Sto raccogliendo le inforrmazioni per riusciere ad ottenere un driver 
per questa macchinina.

Sto quindi chiedendo agli specialisti della lista: quali sono le 
informazioni necessarie per realizzare un driver. Cosa serve 
esattamente: tipo del chip, etc.? Driver già esistenti per windows?
Quali maggiori informazioni potrei chiedere all'azienda fabbricante 
per poter fare il driver? Posso avere un contatto con i tecnici 
dell'azienda, ma gli posso chiedere solo poche informazioni: quali 
sono utili?

Grazie in anticipo di ogni informazione.

Qua sotto alcune prime informazioni techniche.

The Working Device List lists only one product by this vendor; 
http://www.qbik.ch/usb/devices/showdev.php?id=1007 That one has 
device ID 1001 and it is claimed not to work. YOu might be
out of luck. (I'm not sure why the person who provided the above report
picked ACM as its driver).
