[Bug 35638] Re: Hl-1050 is not detected properly
On Feisty this has improved. I can no longer make the printer disappear permanently. However doing repeated runs of the cups usb backend produces differing results: while true; do /usr/lib/cups/backend/usb; done direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER;� direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER;�� direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER; direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER;�� direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER;�� direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER; direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER;�� direct usb://Br/Unknown Unknown Unknown USB #1 MFG:Br direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050 series USB #1 MFG:Brother;CMD:PCL5,PJL,PCLXL;MDL:HL-1050 series;CLS:PRINTER;P� Running the above in two separate terminals will sometimes make the printer briefly disappear from one of them. However stopping the polling in the non failing terminal will then make the printer reappear in the failing terminal.

This problem is still here in Ubuntu Edgy but as previously mentioned it could be a hardware fault... -- Hl-1050 is not detected properly https://launchpad.net/bugs/35638 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

OK after a lot effort I have narrowed this down a bit. I can show the same problem using: watch -d=cumulative --interval=0.5 /usr/lib/cups/backend/usb as root on two different consoles. It doesn't take long for them to start alternate showing and not showing the printer and if you are unlucky the printer will suddenly disappear and not come back until it is unplugged and replugged in. I'm guessing this is either a hardware fault or that that the kernel USB driver on my system is a little bit flakey. -- Hl-1050 is not detected properly https://launchpad.net/bugs/35638 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I don't tend to do dis-upgrades willy nilly. However I have recently upgraded CUPS packages which I suspect was what you were getting at. The output of lpinfo -v has changed to: network socket network beh network bluetooth direct usb://Brother/HL-1050%20series direct hp:/no_device_found network http network ipp network lpd network smb but as before from time to time the direct usb:// line will disappear even though the device is still shown in lsusb and there are no messages of its disappearence in dmesg. ** Changed in: gnome-cups-manager (Ubuntu) Status: Needs Info = Unconfirmed -- Hl-1050 is not detected properly https://launchpad.net/bugs/35638 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

There's nothing out of the ordinary in dmesg...

The printer continues to show up in lsusb. Here is the lpinfo -v when the printer has disappeared: network socket network beh network bluetooth network http network ipp network lpd direct canon:/dev/usblp0 direct epson:/dev/usblp0 network smb Notice how direct canon and direct epson are still there.
