Roaster Not Connected - Linux

Roasting on the Bullet
5

Hmmm, thanks to Matthew and tacvbo (and a little review of syntax), I’ve gotten my computers to recognize the Bullet. Still get the “Roaster Not Connected” message from RoasTime.

I will keep fumbling on. dmesg result is:

Swapped out USB cable, and managed to get rid of the USB disconnect issue. Still no conversation with RoasTime…still ‘Roaster Not Connected.’

No connection between roaster and Artisan either. Message on Artisan is something like ‘AillioR1’ object has no attribute ‘parent pipe’.

New dmesg output:

The SerialNumber appears to be unlikely, but probably not important. Everything else looks reasonable to my untutored eye. Running out of ideas.

Hah - Success…sort of. The driver Linux uses for the Bullet is the cdc_acm driver, written by CCS. On the CCS website, there is a hint that to receive data from the USB device, one must execute (in a terminal) cat /dev/ttyACM0 (the ACMzero, is my specific situation, of course, others will vary). With that process running in a terminal, the Bullet connects with RoasTime.

The big downside to this news is that I will need to run RoasTime as Administrator, which I really don’t want to do. My lesser user(s) can’t run sudo with the right PW. Oh well, maybe there’s a stroke of inspiration in my future.

8

Glad you got it figured out!
I will ask Matthew about why it needs to run as admin.

9

Ok, with the help of your post here, I was able to get mine working (without administrator). This is on Ubuntu 20.04, your mileage may vary on other distros.

Step 1, add the following udev rules - edit the file /etc/udev/rules.d/99-aillio.rules and make the contents look like this:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5741", MODE:="0666", GROUP="dialout"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="a27e", MODE:="0666", GROUP="dialout

Step 2: Reload your udev rules:

$ sudo udevadm control --reload-rules

Step 3: Add yourself to the dialout group.

$ sudo usermod -a -G dialout yourusername

Step 4: Log out, and back in.

Step 5: Unplug the usb for the roaster (if it was plugged in) and plug it back into your computer.

Step 6: Start the RoasTime application.

That’s it, you should be good. As far as I can tell, no cat is required. When you first connect the roaster, /dev/ttyACM0 is available with dialout permissions, but when you connect the app, it goes away (not really sure how this works) and something like /dev/bus/usb/001/005 is used instead.

If you are having trouble getting it to work without administrator, launch the app as administrator and let it connect to the roaster. Do something like this in a terminal:

$ sudo lsof | grep -i aillio | grep usb

It should show the usb device it’s using. Then you can type:

$ ls -lh /dev/bus/usb/001/005

It should return something like this:

crw-rw-r-- 1 root dialout 189, 0 Jun 16 15:38 /dev/bus/usb/001/005

If it’s not in the dialout group, something is wrong with your udev rules.

10

Thanks for this!

11

Thanks – worked like a charm with Elementary OS (Linux)

12

Hi everyone. I am still unable to connect the roaster, after trying the various suggestions in this thread. I am hoping these excerpts might assist someone in the community.

Hi Robert, I am using Kubuntu. It looks like you are using straight Ubuntu which should be fine. Clearly your problem is not the USB cable since the OS sees the Bullet. I had this problem with two different laptops and two different Linux distros. Both times, Arolsen’s instructions above solved the problem. If I were you, I would check the steps again. Sorry this is not more definitive. JP

14

Hi Patrick9724,
Thanks so much for your reply. My laptop is actually running mint 19.1 (but yes, based on Ubuntu). I rechecked my adherence to the instructions - with no joy.
I also came across this usb modem - Connecting a pyboard via USB gives "Could not grab port (tty/ttyACM0)" - Ask Ubuntu
I have disabled the ModemManager.Service and tried again.

15

Sorry to be so late in replying, Robert. Have you tried to change Linux distro?

16

Worked a treat for me on KDE Neon (Ubuntu based). I had to reboot for changes to make effect.

17

Its missing a " at the end. I copied and pasted the udev rules and it didn’t work until I found and replaced it.
SUBSYSTEM==“usb”, ATTRS{idVendor}==“0483”, ATTRS{idProduct}==“5741”, MODE:=“0666”, GROUP=“dialout”
SUBSYSTEM==“usb”, ATTRS{idVendor}==“0483”, ATTRS{idProduct}==“a27e”, MODE:=“0666”, GROUP="dialout "

Hello, I’m hoping for some advice in this area. I have been able to open the Linux 4.6.36 AppImage file on my Chromebook. But it shows “Disconnected”. When I attempt to update the drivers it flashes that there’s a problem installing some dependencies and restarts RoasTime.
I’m not experienced at all with Linux. If there are instructions available about what to enter into the terminal, I could copy them. I’ve looked at the advice earlier in the thread and am not sure how to begin. Thanks if you see this and answer! Mark

19

thank you!

Hey there not sure if anyone is still having issues with Linux connections

I’m running :

  • laptop: Framework 13 laptop on a Ryzen AI 5 340 processor
  • image: the latest App image RoastTime-4.13.6.AppImage
  • distro: Arch linux (Omarchy)

and I’ve tried all these steps listed in the thread.

Running lsof

gives this output:

lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc
      Output information may be incomplete.
lsof: WARNING: can't stat() fuse.RoasTime-4.13.6.AppImage file system /tmp/.mount_RoasTivDBwo1
      Output information may be incomplete.

but I think that’s okay

running lsusb looks like it’s clearly detecting the Bullet:

going to give this post that has a similar bash script as well, will report back: Ubuntu Linux - #4 by mcaillio

Update here:

I also tried:

Still no luck :confused:

22

@ryantulleris.D94j Are you running an R1 or R2? They have different product ids.

23

Sorry should have added to my original message -R2. Where can I locate the correct product ID I should be entering?

here is my output of lsusb:

So I’m assuming it’s vendorId:ProductId ? so 0483:a4cd

After that assumption I tried this in my /etc/udev/rules.d/99-aillio.rules file:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="a4cd", MODE="0666", GROUP="dialout"

but it looks like I’m missing another line based on some posts here in the thread

24

So, for anyone that comes to this in the future:

Each line in your udev rules is a specific USB device. 0483 is the vendor id for all Aillio devices. 5741 and a27e are the Bullet R1s. For an R2, you need to add a4cd

Next, the user group dialout is specific to some Debian flavors. For Arch or others, you probably need to create a new user group to add both the rules and your user to and then reload the rules.
