Troubleshooting Connection Issues

Update RoasTime

RoasTime is updated frequently to fix bugs and add new features. Before proceeding, please try downloading the latest client RoasTime 4

Step 1: Determine if the problem is hardware or software

The first thing we need to do is figure out if you have a hardware or software issue. Every OS has tools available to see if the roaster is seen by your OS. Here are common ones:

Windows:

In your Windows search bar, type “Device Manager” and open it.

• The roaster should show in Device Manager as "Aillio LTD Bullet R1 Roaster FS".
• Or for R2 Pro and R2 users, it should show as "Aillio LTD - Bullet R2 CDC".

---

MacOS:

Open Terminal with Command + Space and type "Terminal".

Copy this command ioreg -p IOUSB -l -w 0 and press "Enter" to list devices.

You should see the Bullet by looking for an output similar to this:

---

Linux:

lsusb from Terminal should show you the Bullet in the list.

Hardware or Software Issue

If the roaster is plugged in and you do not see it in the Device Manager or Terminal output - you have a hardware issue. Try a new cable and if the issue persists, open a ticket at [email protected] and mention the steps you took.

Step 2: Confirm you have the correct drivers

⚠️ Skip this step if you are not on Windows ⚠️

R2 Pro & R2 users on Windows

If you are using an R2 Pro or R2 on Windows, you must be on RoasTime 4.9.0 or later. The version is displayed in the title bar of the software. If you are not, please download the latest version from RoasTime 4.

We use libusb drivers for MacOS and Linux and they come packaged with the application. You should not need intervention for these operating systems. On Windows, we use WinUSB drivers. These must be installed once.

In RoasTime, you can navigate to Settings > Software, and find the "Re-Install" button under USB Drivers.

Please confirm any following prompts from your system and firewall to allow the installation to proceed.

Install drivers manually

If the automated tool is not working, please follow these steps to install drivers manually:

1. First power up your Bullet
2. When it is ready connect it to your laptop/PC using the supplied USB-cable
3. Download Zadig from here: https://github.com/pbatard/libwdi/releases/download/v1.5.1/zadig-2.9.exe
4. Run the downloaded file (zadig-2.9.exe)
5. Choose “Options” and make sure “List All Devices” has been checked
   
6. Choose the “Aillio LTD….” Interface. If there is more than one interface choose the one that ends with “1”
   
7. Click "Replace Driver"
8. When the installation has been completed then restart RoasTime 4

Step 3: Restart everything

If you have made it here, you definitely have a software issue. Sometimes we have seen the roaster remaining unreleased after a crash or some other issue arising which results in us being unable to claim the roaster again.

This situation should be able to be resolved by:

1. Unplugging the roaster
2. Unplugging the USB
3. Closing RoasTime
4. Plugging everything back in
5. Starting up RoasTime
