Title says it all. But I plugged in an external DVD drive into my Raspberry Pi running Raspbian. It says its Linux compatible

However when I actually plug it into the device. Everything goes wrong in incomprehensible ways.

SSH says "kex_exchange_identification: read: Connection reset by peer. Connection reset by 192.168.50.2 port 22"

Or when I do "ls" it says "-bash: /usr/bin/ls: Input/output error"

Or when I do "sudo" it says "-bash: sudo: command not found"

Nothing really works with it plugged in.

However when I reboot the RaspberryPi all is well... up until I plug in the DVD drive.

What is going on? How can I troubleshoot or fix it given so many commands are down? What might've happened?

Investigation updates $PATH Before /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games After - Same BUT this is odd to me. This is a newly configured version of the OS. Why is it pointing to games and all of these other things? Odd?

DVD drive "hyripe external cd/dvd drive"

Another thing that seems potentially relevant. Device is booting and using an external SSD plugged in via a USB port as memory.

  • Does the external DVD drive use its own power supply? Or is it connected via a USB hub with its own power supply? Commented Mar 27, 2024 at 21:37
  • In line with @KamilMaciorowski's comment: Is your OS'es drive (presuming sdb here) also using a USB port since this is a Pi? The issue here as Kamil has picked up on is overcurrent. See seconds 89 -91. See the Pi Forums: External DVD Commented Mar 27, 2024 at 22:13

This is a guess, but I suspect if you change your plug arrangement to use a USB hub - instead of plugging the DVD directly into a USB port on the RPi - that your problems will disappear.

FWIW, you've not given us much to go on: no model #, no OS version, no info on power supply, no info on DVD current requirements, etc.
