@tom Thank you. I will submit an RMA request.

@tom Yes, I tried different USB-C cables, different USB ports, and even different laptops (Windows and Ubuntu 22.04, both running natively - not a VM).
The result is the same in all cases.

When the VOXL 2 Mini is powered with VBAT and I plug in USB-C, nothing appears in dmesg and ADB does not detect the board.

@tom I ran dmesg -wH and monitored the output while powering the VOXL 2 Mini with VBAT and then plugging in the USB-C cable. There were many existing system messages, but when I connected the VOXL 2 Mini, no new lines appeared at all in the dmesg log.

Thank you.

@Vinny Thank you for your support.

Regarding the power module: I did not modify it. I received it exactly in this condition. I have not opened or altered the module.

I have tried all the recommended steps including powering with the module off -> then ON -> then inserting USB-C, as well as using different laptops, different USB cables, and different ports on both Windows and Ubuntu, but the issue still remains the same.

@Vinny @tom Thank you for the support. I’m using Linux, and here is the output of lsusb with the board powered and connected.

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0bda:5522 Realtek Semiconductor Corp. Integrated_Webcam_HD
Bus 001 Device 004: ID 8087:0026 Intel Corp. AX201 Bluetooth
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

There is no Qualcomm/QDL device listed.

The board was functioning correctly before an unexpected laptop shutdown, but after that it stopped responding. With only USB-C there is no LED, and with VBAT I only see a dim green D1 LED and the board does not boot. Please advise on next steps.

Thank you.

@tom Thank you for your response. I’ve attached the pictures of your hardware setup for your review.

Hi ModalAI Support,

I am experiencing an issue with my VOXL 2 Mini.

I had the VOXL 2 Mini running from the 12 V power module and simultaneously connected to my laptop over USB-C. Everything had been working normally, but suddenly my laptop shut down. After that event, the USB-C port on the VOXL 2 Mini stopped functioning.

Current behavior:

When connected through USB-C only, the board does not power on (no LED, no ADB connection).

When powered using the 12 V adapter, I only see a dim green LED. The board does not fully boot and does not appear over USB when connected to a laptop.

It seems that either the USB-C port or part of the power/USB circuitry may have been damaged.

Could you please advise on next steps or whether this board needs repair or replacement?

Thank you,
Ashish Kumar
