Greetings, I bough an OAK-D Camera from the amazon store about 2 month ago. I tried the DepthAi Demo, it was working normally. Yesterday it didn't work for some reason. I have the latest DepthAi Repo and Requirements. [URL=https://i.imgur.com/D7YL4Ag.jpg][IMG]https://i.imgur.com/D7YL4Agh.jpg[/IMG][/URL]

Hello @"Salem"#p3526 , We apologize for the inconvenience. Could you please run the demo in [trace mode](https://docs.luxonis.com/projects/api/en/latest/tutorials/debugging/), so `DEPTHAI_LEVEL=trace python3 depthai_demo.py`? This would help us understand the issue, and if it's a hardware issue we can send you a replacement. Thanks, Erik

Hello @"Salem"#p3534 , I have just noticed you aren't using the release version of depthai. Could you update your depthai to the latest (2.15.3) with `python3 -mpip install depthai -U` and try the same thing again? I would also suggest copying the log into pastebin:) Thanks, Erik

@"erik"#p3535 Hello erik, [here is the log in pastebin after the update](https://pastebin.com/PsKUxHDA)

Hello @"Salem"#p3537 , It looks like you are using USB2 cable. Could you try with an USB3 cable instead, or force USB2 communication with `python3 depthai_demo.py -usbs usb2`? Thanks, Erik

@"erik"#p3538 Hello erik, the camera is connect to jetson nano's usb3 port. the camera was working before using the current cable as i mentioned earlier. [here is the log](https://pastebin.com/SJjeeMuN)

Hello @"Salem"#p3539 , The camera is booted in USB2 mode, which could be the source of the problem. Could you try the suggested options mentioned above? Thanks, Erik

@"erik"#p3544 Hello erik, I bought a new usb3 cable, didn't seem to help with the Demo. The following examples were tested. - ColorCamera Preview (**Works** with some noticeable Lag). - MonoCamera Preview (**Works** with some noticeable Lag). - Depth Preview (**gives the same error**).

Hello @"Salem"#p3568 , could you share the log you now get? Is it any different, has the usb speed changed?

@"erik"#p3570 Hello erik, [ColorCamera LOG](https://pastebin.com/ib3g5ZKU) [MonoCamera LOG](https://pastebin.com/vw6aec8r) [Depth Preview LOG](https://pastebin.com/v2vuafyS)

DepthAI Demo Used to Work, Now it Doesn't.

here is a summary

the camera's calibration was erased ( i don't know why)
