Gen2 X-Link error

MFavier

Hello,

I have recently purchased an OAK-D device. I have depthai in Kubuntu 20.04 running in VirtualBox on Windows 10.
I have two virtualenv's, for API gen 1 and gen 2. Now, in gen 1 I can run depthai_demo.py and I get an rgb camera output with the NN output overlayed.
In Gen 2, I get the following error when trying to run one of the examples.
Traceback (most recent call last):
File "rgb_preview.py", line 24, in <module>
with dai.Device(pipeline) as device:
RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

So obviously, it cant open the camera. But seeing as in Gen 1 it does work, the most logical explanation would that there is something wrong in Gen 2? Can someone shed a light on this?

Thanks in advance!
Michiel

MFavier Sorry for the trouble.

So we've found that in switching between Gen1 and Gen2 libraries, it is necessary to fully power cycle the device (i.e. unplug it from USB and power).

I'm wondering if that is the issue here.

Thakns,

Hello Brandon,

Thanks for your reply. I tried this a couple of times already. I power the device via USB3.
This also happens when I do a fresh start using just gen 2.

Hello MFavier, does your computer find the depthai with lsusb? Or with dmesg -w, could you share the log when you plug in the device?
Thanks, Erik

Hello erik,

This is the output of lsusb;
Bus 001 Device 010: ID 03e7:2485 Intel Movidius MyriadX

dmesg output:
[31267.161930] usb 1-3: new high-speed USB device number 11 using xhci_hcd [31267.471104] usb 1-3: New USB device found, idVendor=03e7, idProduct=2485, bcdDevice= 0.01 [31267.471111] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [31267.471116] usb 1-3: Product: Movidius MyriadX [31267.471119] usb 1-3: Manufacturer: Movidius Ltd. [31267.471122] usb 1-3: SerialNumber: 03e72485

My novice reasoning is that there is nothing wrong with the hardware, seeing as Gen 1 works as it should. I could be wrong though. I look forward to further suggestions.
