[hotdobb]

Hi i am unable to connect the artisan 4.0.2 to the bullet
comport is correct same setting as in win device manager
in artisan i have set machine bullet v1 ibts
the aillio runs with firmware 6.45 (latest)
error is aillio r1 : unable to configure
i did all possible solutions lke uninstall roastime and all non sense AI sugestions
if some one have any idea pls help

The COM port setting is probably a red herring for this profile. The Aillio R1 IBTS driver path in Artisan uses USB/libusb, not a normal serial COM port.

In the current code, Aillio R1 : unable to configure is raised while Artisan is trying to call set_configuration() on the USB device, before it can read the firmware/version info. So I would check the Windows USB driver binding first.

On Windows, older Bullet R1/IBTS connection issues in this repo were fixed by installing the legacy libusb-win32 (v1.2.6.0) driver for the Bullet device. The practical route is usually:

1. Close RoastTime completely.
2. Plug in the Bullet.
3. Run Zadig as Administrator.
4. Select the Aillio/Bullet device, not a COM port.
5. Install/replace the driver with libusb-win32 (v1.2.6.0).
6. Unplug/replug the Bullet, then start Artisan and use Config > Machine > Aillio Bullet R1 IBTS.

This may affect whether RoastTime still sees the roaster, because Windows binds one driver to that USB device. But for this exact Artisan error, I would not spend time changing COM-port settings until the USB driver binding is confirmed.

thx for your answer
i did your sugestion and i have now the error invalid endpoint 0x3 and artisan shows steady 32 temp reading
i startet rostime for usb driver test it works properly with the zadig driver
i did similar uproach with all zadig drivers available and artisan still not cooperating
i think the AILLIO firmware IS buggy unfortunatly i cant roll back to previous vertion

Correction to my earlier driver suggestion: I rechecked current Artisan source/release history locally, and for recent Artisan versions on Windows the Aillio R1 path expects WinUSB, not the old libusb-win32 driver. Artisan 2.10.x changed Aillio Windows connectivity from libusb-win32 to WinUSB.

For R1 the code expects:

• VID 0483, PID 5741 or a27e;
• interface 1;
• write endpoint 0x03;
• read endpoint 0x81.

So invalid endpoint 0x3 means Artisan is reaching a USB device, but the interface exposed to pyusb does not contain the expected write endpoint, or Windows is binding Artisan to the wrong interface/device. The steady 32 reading is consistent with failed communication; I would not conclude firmware bug first.

What I would try next:

1. close RoastTime completely before starting Artisan;
2. in Zadig, enable Options -> List All Devices;
3. select the actual Aillio Bullet R1 device/interface, not a COM/CDC entry;
4. install/replace that interface with WinUSB;
5. unplug/replug the Bullet, then start Artisan and select the Aillio Bullet R1 IBTS machine setup.

If it still fails, please attach a USB descriptor dump from UsbTreeView or Zadig showing the Bullet VID/PID, interfaces, and endpoints, plus the exact Artisan and Bullet firmware versions. That will show whether the firmware descriptor changed or the wrong Windows interface is selected.

I cannot verify this against hardware here, but the local source and unit tests confirm that endpoint 0x03 is the expected R1 write endpoint.
