[Pkg-cups-devel] Bug#370604: cupsys: Cupsys 1.2.1 fails to "wake" sleeping USB printer any more

[Matthew Exley]

Package: cupsys
Version: 1.2.1-1
Severity: important


Since upgrading to Cupsys 1.2.1, printing has become most unreliable.

I have a Brother HL-1430 attached via USB; this worked fine under Cupsys 1.1.x.
The printer goes to a low-power sleep mode if inactive for 5 minutes.

Under 1.2.x, if the printer is in sleep mode, attempts to print to it are met
with the Web interface message:
	"/usr/lib/cups/backend/usb failed"
or:
	"Unable to open USB device, queuing on next printer in class..."

And with LogLevel = Debug, the following final error message is repeated in
/var/log/cups/error_log:
>
>E [06/Jun/2006:02:44:19 +0100] PID 23207 (/usr/lib/cups/backend/usb) stopped with status 1!
>
(There's lots of other rubbish in there; this seems to be the most useful message)


As a work-around, unplugging and replacing the USB cable causes everything to wake up, in
particular I believe Hotplug comes to life and detects a new printer. CUPS will then happily
flush the queue and/or print any new jobs that come along right up until the idle timeout
kicks in again and the printer goes back to sleep. 

So I deduce that something is failing to issue the appropriate kicks to wake up the printer
in 1.2.1.

BTW I'm using the PPD from:
/usr/share/ppd/linuxprinting.org-gs/Brother/Brother-HL-1430-hl1250.ppd.gz
(Brother HL-1430 Foomatic/hl1250 (recommended))

And the device is connected on:
