Thanks for this!
Thanks – worked like a charm with Elementary OS (Linux)
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
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.

Sorry to be so late in replying, Robert. Have you tried to change Linux distro?
Worked a treat for me on KDE Neon (Ubuntu based). I had to reboot for changes to make effect.
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
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:

Not sure what else I can try if anyone has ideas thank you all!
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:
- the Roast Time GUI “Install USB drivers”
- and the thread I mentioned in my last post. Ubuntu Linux - #4 by mcaillio
Still no luck 
Sorry should have added to my original message -R2. Where can I locate the correct product ID I should be entering?

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
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.
Okay gotcha
I’m still not clear on a few things:
- what does the second rule need to be besides the one in my last post? My rule has the a4cd product
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="a4cd", MODE="0666", GROUP="dialout"
- I did add the dialout group with
groupadd dialout $USERis that what you meant?
Thanks @mcaillio !
Hey @ryantulleris.D94j ,
You don’t need a 2nd rule. The single line should cover it. I believe on Arch, the equivalent of dialout is uucp. So you can set GROUP="uucp" and then sudo usermod -a -G uucp $USER
And then re-login.
Wow you’re the best (everyone in this thread) + @mcaillio the uucp is all i needed. It’s working!
Take care everyone

i’m running Ubuntu and run an app image of the latest roast time and have been following the thread and when i checked the rules, i can’t seem to find the 99-aillio.rules file.
You will need to create the file, you will likely have to sudo and give the file read write permissions. After you create the file then go back and follow the steps in the thread
