There's nothing out of the ordinary in dmesg... [4294957.288000] usb 1-2: new full speed USB device using uhci_hcd and address 3 [4294957.415000] drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 3 if 0 alt 0 proto 2 vid 0x04F9 pid 0x0002
There are no other usb events in dmesg even though the printer appears and disappears from lpinfo -v . 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. These go when the printer usb cable is unplugged... ** Changed in: gnome-cups-manager (Ubuntu) Status: Needs Info => Unconfirmed -- Hl-1050 is not detected properly https://launchpad.net/malone/bugs/35638 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
