Christopher, maybe I'm barking up the wrong tree here. After booting yesterday into the 4.0rc kernel without the printer working and then back to the 3.13.0 kernel with the same result I booted this morning into 3.13.0-46-generic #77-Ubuntu SMP Mon Mar 2 18:23:39 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux. I had been noticing this during boots but never paid attention to it:
Mar 8 08:40:10 localhost kernel: [ 19.500050] usb 1-3.4: device descriptor read/64, error -110 With the printer turned on and plugged into my Belkin 7 port USB hub and an indicator light showing for that port I then run lsusb -v -v -v from a terminal: Bus 001 Device 033: ID 03f0:2b17 Hewlett-Packard LaserJet 1020 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x03f0 Hewlett-Packard idProduct 0x2b17 LaserJet 1020 bcdDevice 1.00 iManufacturer 1 Hewlett-Packard iProduct 2 HP LaserJet 1020 iSerial 3 JL1F0DC bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 32 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xc0 Self Powered MaxPower 98mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 7 Printer bInterfaceSubClass 1 Printer bInterfaceProtocol 2 Bidirectional iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x01 EP 1 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Device Qualifier (for other device speed): bLength 10 bDescriptorType 6 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 bNumConfigurations 1 Device Status: 0x0001 Self Powered The printer seems to be recognized however I can't print a test page from the CUPS web interface nor can I print any documents. The HPLIP popup shows the job starting and stopping however the CUPS interface shows the job(s) as being held. So, question is Christopher where do I jump to in trying to debug this or at least find the answer? I've Googled and even gone so far as shutting down, removing the computer power cable and waiting a few minutes then bringing it back up again as was suggested as a fix on one Ubuntu forum. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1428356 Title: USB printer will not print after boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1428356/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
