Yes, that's better. Because I haven't a printer behaves such sleep action, it's hard to reproduce the problem. In my code investigation, the problem occured at open_device() of backend/usb-unix.c. open_device returns fatal error when: - user used obsolete usb:/dev/ style. usb URI should be usb://Vendor/Hardware style. - accessing to /dev/usb/lp0 was failed by something error except of EBUSY. So, - Please make sure your /etc/cups/printers.conf uses usb://Vendor/Model style. - Is there /dev/usb/lp0 in your environment? If there is, what's happen when you execute "cat < /dev/usb/lp0" during a printer is sleeping. - Is there any wakeup/sleep or connect/disconnect message about a printer in your /var/log/syslog? - When you run "/usr/lib/cups/backend/usb" with root privilege, what message do you see (during sleep, and during wakeup)?
