I am using Slackware 14.2 (64 bit) as my operating system, and for some reason, it doesn't recognize my USB DVD rom drive. Any suggestions on how to correct that?

Can you plug it in and do:
Post the output.
BTW does it self-power via USB power or does it have a power plug?

If it doesn't show in lsusb, try dmesg.

dmesg creates quite a bit of output, so you might want to pipe the output to a file

and examine the file in a text editor. You may have to run dmesg as root.

And the output for that is:

bash-4.3$ lsusb

And yes, I have libdvdcss installed on my system. But the interesting thing is that my system DOES recognize when I insert a video DVD into the drive (external USB DVD drive).

There is LG (HLDS) in the lspci output posted by you.

How do you know that? What program(s) is/are unable to find your DVD ?

.

So it does recognize it. Silently. Don't expect an icon to appear on the desktop until you have loaded a disk into it. This is normal behavior.

xine, and I already set it to read from /dvd/sr1

Try /dev/sr0 (or /dev/sr1, if you have another DVD drive).

Hi,

As you have found out that media must be present in order to recognize the device to you. If you want to see if the kernel has recognized then the output of 'lsusb' or looking at 'dmesg' should show the device in question.

As root you can use 'dmesg | grep -i dvd' to look at the initial recognition of the device; Please note the sr0 device in the output above.

Your desktop/DE will not show the device until you load it. Be it video or data then you should get the device recognized thus allowing action on your part.

For future references, I suggest that you read http://www.linuxquestions.org/questi...#faq_lqwelcome so you can compose a post that will be helpful to you so we can use information to enable us to help you diagnose issues.

Hope this helps.
Have fun & enjoy!

Ok, I'm sorry that I didn't give such good information before about the problem that I am having trying to view DVDs with xine (my brain doesn't always function as well as it should ), but anyway, the message windows that keep popping up can bee seen in the attached screenshot, and yes, I have libdvdcss installed. I hope this helps.

There's no screenshot.

And can you start xine in the command prompt and provide the output here?

Sorry about that - hare is the screenshot, and also the output from terminal mode as well (I am trying to view it with my external USB DVD drive):

Is this a second disc drive? Because I think I remember reading above that it should be /dev/sr1, but xine is using /dev/sr0, which if you have an internal device, would be that one.

You'd probably need to go in to the settings of xine to change the default dvd device.

I DID change it to sr1, and I have been getting the output that I showed you - thats what I have found so odd about it.

Well, according to your image, xine is still searching for /dev/sr0.
You should be able to manually navigate to /dev/sr1 through the "Open" menu in xine.
