usb dvdrw not detected unless unplug and replug

You can just run:

sudo mount -a

and it will mount.

Can you have the device attatched and run:

sudo lshw -C disk; echo; cat /etc/fstab

Thanks

I think I may have fixed it by changing my bios to the optimized settings. Now it seems to boot from it and once the system is up and running it mounts when I insert a disk. I am still running tests, but it looks fixed.

I ran the mount command and nothing happened. Here is the lshw and cat.

Well as you can see there is now a /dev/dvdrw and an entry in fstab so it should now be good to go. Is it ok?

I added the entry to try to get the system to mount the dvdrw. The /dev/dvdrw only shows up if the mother board sees the dvdrw on boot up. If this happens then the dvdrw shows up in Disk Utility. It seems to be working for now. I will continue to do testing.

The drive seems to be detected by the bios when I turn off the quick post test and then the dvdrw shows up in the Drive Utility. There still seems to be a long time detecting something on boot up before it loads the OS. I am still testing under different circumstances to see what the cause may be.

I still don't know what caused the original problem but I fixed it by taking out the old ide drives, which I don't need anymore, and hooking up the dvd drives to the ide connector and not using a usb drive. I also still don't know what it was looking for but that fixed the long boot up time as well.
