@maheshs11 could you try with working USB3 cable? In case of RPi, it got only USB2 connection link. For windows, device was already in use (reconnecting might help).

[maheshs11]

@Erol444 on windows tried reconnecting does not work,
in device manger myrad changes to luxions with sound and again reverts to myrad is this expected behaviour?

Rpi also has 2 blue usb 3.0 ports right?, will try after getting new cables.

[Erol444]

Yes please try with different cables, you are still getting only USB2;

USB Connection speed: UsbSpeed.HIGH
Enabling low-bandwidth mode due to low USB speed... (speed: UsbSpeed.HIGH)

[maheshs11]

@Erol444 tried changing cables still same issue,
ran command log_system_information.py, found this is it relevant?

"usb": [
    "No USB backend found"

}

[maheshs11]

partially solved the issue, the issue is not related to cable i guess, As mentioned in issue #691, reverting back to depthai V1.13.1.0 works for mono camera, but issue still persists for rgb camera.

[maheshs11]

In windows temporary solution to use v2.21.2.0 is to force re-install depthai package and restart and remove usb cable, only monocamera works, for rgb same issue as #749

[maheshs11]

@Erol444 , bought short usb3.0 , device not found error. Not showing in device manager y?

for blue colour usb 3.0 : no logs no device found error

[Erol444]

Did you setup the udev rules? The device does get detected by linux (Movidius MyriadX)

[maheshs11]

Yes, I did setup udev rules, it get detected with only usb2 cable and orange cable 3.0 and the error comes low speed and above error, for blue color usb 3.0 cable it does not get detected.

[Erol444]

OAK will always get detected as usb2 by default, after you init the device it will (if it can) switch to usb3.

[maheshs11]

Low speed error comes and closes, if required for debugging error will give acess to my vnc server.

[Erol444]

@maheshs11 sorry about the delay. Have you tried using our preconfigured RPi image?

[maheshs11]

@maheshs11 sorry about the delay. Have you tried using our preconfigured RPi image?

No, will try it.
