Re: [LUG] DVD Drive

[Mark Thurston <mark@xxxxxxxxxx>]

I am running Ubuntu 21.04 and I am trying to mount a portable dvd drive onto the desktop. The results from lsusb are:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 04d9:a0cd Holtek Semiconductor, Inc. USB Keyboard
Bus 001 Device 003: ID 046d:c077 Logitech, Inc. M105 Optical Mouse
Bus 001 Device 002: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I know that it will be device id 001 but there are 2 listed! How do I mount or see this drive and also play or burn dvds from it please?

I can't see something in that list that is obviously a DVD drive. The "Linux Foundation root hub" probably refers to the USB controller chip rather than a plugged in device. The following might be worth trying:

# look for info in the kernel ring buffer specific to DVD drives
sudo dmesg | grep -i dvd

# list all block devices (probably doesn't require sudo)

sudo lsblk

# monitor the log file

tail -f /var/log/messages

# now, unplug and plugin the drive and see if anything happens

# install wodim (cdrecord program) and view more info about identified scsi devices

sudo apt update && sudo apt install wodim

wodim -scanbus

Hopefully one of these may get you a bit further (at least produce some debugging information)!!
