Unable to access USB Ports

[ChaosUntamed]

Please paste the output of the following command here: sudo edit-chroot -all

Please describe your issue:

Hello everyone,

I installed Ubuntu Focal Fossa 20.04 on my old chromebook using this site as a guide. Everything seems to have gone just fine. But now, when I plug something into the USB ports, it pops up in the File Directory. But it only lasts a second or two and then disappears.

This only happens in the chroot environment. In the ChromeOS environment, the USB ports work fine. I did not provide the information above because the command returned an error that said it was not found.

Any help would be greatly appreciated. I need the USB ports to work to connect my 3d printer to the chromebook.

If known, describe the steps to reproduce the issue:

[TomTravis]

hello i assume your using the cups printer driver
yes to ports are closed in change root
#143
my suggestion is to print spool in lpr to a file and send it via chome lpr not cups

or open the port
port 631
CUPS uses port 631 (TCP and UDP), which is the standard IPP port, and optionally on port 515 by inetd, launchd, the Solaris Service Management Facility, or xinetd which use the cups-lpd helper program to support LPD printing.

Wow. That was way more complicated than I can even comprehend.

What I intended to do was install OctoPrint in the Linux environment and connect the printer via a micro USB (printer) to chromebook (usb).

But I need the USB ports to be accessible from the Linux environment. Would opening Port 631 do that? And how would I do so?

[TomTravis]

it make cups happy
read this
#143
save the output as a file spool later
great

open the the port take for CLI read in discussion about it

[ChaosUntamed]

I'm sorry, I just don't understand what you're saying. Should I be following what they did in the #143 post? Even though that seems to be for a regular printer and not a 3d printer?

Is there something I should be following in the OctoPrint link? I'm very sorry, I'm just very confused...

[TomTravis]

octo print has a tcipip server octoserver use it
the print server is if you need it
you send cmd via a usb port or internet port it the same thing

[ChaosUntamed]

octo print has a tcipip server octoserver use it

Will this solve my usb port problem?

[TomTravis]

yes i have no idea you have to test it
USB is hardware tcpip is software

[ChaosUntamed]

yes i have no idea you have to test it

I would love to. If I even knew what "it" is. I know very little about any of this. I've just been trying to figure out how to use OctoPrint on this chromebook I bought and it has led me down a very long, dark tunnel that I know nothing about...

I'm sorry if I'm wasting your time. I just don't understand any of this.

usb print hub server tcp/ip

this is you plug and play

[ChaosUntamed]

How will that help when the chromebook won't read from the USB ports in the Ubuntu environment? Wouldn't that have the same problem?

[TomTravis]

forget USB on the CB
octoprint serve is a tcpip serve the connect to the usb print server via the wireless network no usb ubuntu needed

[ChaosUntamed]

I would rather see if I can get my USB ports to work on the CB. Maybe that sounds dumb and is overly complicated, but I've already invested money and a lot of effort in this route.

That said, if I can't get the USB ports to work, I'll see if I can't figure out how to use the Print Server that you posted as an alternative. Thank you for explaining things to me and taking the time to work with me on this.

join the club so time is money play with USB drivers in Octoprint that does not use them
or 39$ it works

[ChaosUntamed]

That's a fair point. If I got that device. How would I use it?

[TomTravis]

read octoserver port 8080 send to print server simple config
you use via octoprint octoserver no USB is needed on chromebook(linux)
git clone https://github.com/OctoPrint/OctoPrint.git
build and install

[ChaosUntamed]

I've had a long day and apparently my mind just isn't working with me. I'm utterly confused.
From my limited understanding currently, I get the device and plug it into my 3d printer. Then load octoprint up on my CB and access the wifi signal via the Ubuntu terminal using the commands specified. No idea what the "build and install" part means.

I don't know that that's right, but I'm gonna try to sleep on it and read through this again. Maybe it will click for me. Again, thank you for all your help.

Reading back through all this. I'd like to try opening port 631 and maybe 515.

CUPS is installed. How do I open a port using it? Specifically, what commands?

[TomTravis]

yes okay you like tcp then join the team and we go from there you have a invite and task

the command are not cli and you submit a table with command kinda like a print job
man ip-tables

[ChaosUntamed]

Join the team? What exactly do you want me to do? I don't know enough about this stuff to even understand a single thing you said...

I'd love to help, but I'm drowning in my own inadequacy here. Very much out of my element.

[TomTravis]

you have a invite yes, systemd chroot team you cannot fail it does not work yet ;-0

here is a IPtable port 22 is open tcp 22 d,s IO sshd init service sort like cups

What is the output of sudo lsusb command (inside chroot) after you connected the 3d printer?

Btw better to not listen to the guy above, I don't think he understand what he said. (it seems that all of his comments were directly copied from results in google)

This is what I get from that command.

Oh, wait. I missed the 'connect the printer' part until just now. One second.

tcp is the way octoprint is not usb

Even beyond this, I'd like to get my usb ports working just to use other things that connect via USB. Such as memory drives, USB cd drives, and such.

[TomTravis]

well run in /usr/local/bin
yes my camera does not automnt like usb memory, so octoprint does not use usb also you have to make it us this

@Superchicken provided and wonderful solution lsusb, this is why i use the shared drive with chromeOS

[TomTravis]

ok i believe the USB ports devices and not shareable between chromeOS and chroot linux
if one has cmd the other does not

the idea is to get get chrome to stop Automount devices if you wish to use them in chroot
i do not use USB ports that much no need i dont have a cd drive or usb printer only mount phones and use the share folder with chromeOS

you do not have any idea, what have you done nothing
