Oops, "No such device" is indeed a message from the driver (I've confused it with "No such file", which would've meant the driver isn't loaded). I suggest you search the web (especially http://groups.google.com ) for similar experiences with your printer model. Its possible that the generic USB Printer protocol doesn't work with your printer and you need a special driver. Other than that, all I can suggest is reading the driver's source code, learning how the driver works, printk'ing here and there and coming up with a solution yourself. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
