I'm on Ubuntu 16.04.3 LTS (dual boot w/ Windows)
I picked up this external USB DVD writer, model ECD819-SU
I have successfully plugged it in, burned a CD, and listened to the CD in the car, so at one point everything worked fine without doing anything special.
Now many days later I try to burn another CD and things are strange.
Plugging in the USB DVD drive no longer notifies me of a blank disc in it or otherwise appears in Brasero or file viewer.
After searching for similar problems I come across this technique where I unplug and replug the USB DVD drive, then run this:
dmesg | tail [ 1517.648577] usb 3-1: USB disconnect, device number 10 [ 1562.479656] usb 3-1: new high-speed USB device number 11 using xhci_hcd [ 1562.621181] usb 3-1: New USB device found, idVendor=13fd, idProduct=1040 [ 1562.621186] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1562.621189] usb 3-1: Product: \xffffffc2\xffffff92¬A6þ¾\xffffffc2\xffffff80\xffffffc2\xffffff83/µ\xffffffc2\xffffff85\xffffffc2\xffffff87ðL [ 1562.621192] usb 3-1: Manufacturer: Initio [ 1562.621195] usb 3-1: SerialNumber: 00000000000000000 [ 1562.621919] usb-storage 3-1:1.0: USB Mass Storage device detected [ 1562.622179] scsi host6: usb-storage 3-1:1.0 [ 1585.001736] usb 3-1: reset high-speed USB device number 11 using xhci_hcd
Cool so the vendor ID is 13fd and the product ID is 1040.
More searching and I come across http://www.linux-usb.org/usb.ids which reveals some interesting info:
13fd Initio Corporation 0840 INIC-1618L SATA 0841 Samsung SE-T084M DVD-RW ... 1040 INIC-1511L PATA Bridge <--- current PID 1340 Hi-Speed USB to SATA Bridge ... 3940 external DVD burner ECD819-SU3 <--- HEY, this is right! 3e40 ZALMAN ZM-VE350
So that's where I'm stuck. I don't know if the product ID actually changed or has been this way all along. Even though I can see some files with these codes, I would rather not just blindly change values:
/sys$ grep -r "13fd" * 2>/dev/null devices/pci0000:00/0000:00:14.0/usb3/3-1/idVendor:13fd devices/pci0000:00/0000:00:14.0/usb3/3-1/3-1:1.0/uevent:PRODUCT=13fd/1040/106 devices/pci0000:00/0000:00:14.0/usb3/3-1/uevent:PRODUCT=13fd/1040/106
I assume that 106 following 13fd and 1040 is some kind of driver ID, so I'd have to know what the DVD drive driver ID should be, maybe.
Anyway, any suggestions? Should I edit these things, or use some technique to get Ubuntu to totally forget this info and see if it will deduce the correct product/driver from scratch again?
