[Bug] "Invalid descriptor index" on Raspberry Pi 4 with Astra Pro

[LGTIN111]

"Hello,
I am trying to use an Astra Pro camera on a Raspberry Pi 4 Model B (4GB).
System:
OS: Raspberry Pi OS (Legacy, 64-bit, Debian Bookworm)
Kernel: [Dán kết quả của lệnh uname -r]
Steps:
I have successfully compiled and installed the latest version of pyorbbecsdk from source.
lsusb command correctly detects the camera (ID 2bc5:0403 and 2bc5:0501).
I have created the udev rule.
Problem:
When I run a script that calls ob.Context(), I get the following error:
[error][PID][UsbEnumeratorLibusb.cpp:397] Failed to query USB device serial number: Invalid descriptor index
This happens even when running the script with sudo.
Could you please provide any advice on this issue? Thank you."

@LGTIN111 Hi ,

Thanks for reporting this issue.

The error you are seeing:

Failed to query USB device serial number: Invalid descriptor index

indicates that the SDK is unable to read the USB descriptor (usually the device serial number) from your Astra Pro camera. This often happens on Raspberry Pi due to USB compatibility or power issues.

Could you please confirm whether you are connecting the camera to a USB 3.0 port on the Raspberry Pi 4? Using a USB 2.0 port may cause this descriptor read failure.

I have the same issue on using dabai on a rpi5 - I am connecting the camera through a USB3.0 port and a cable that works fine when i connect the same camera to another MacOS computer

Hello Orbbec!

@hammerchu v2.5.5 does not support DaBai devices. Please refer to the README for the list of supported devices.
@LGTIN111 What SDK version are you using? If it’s v2.x.x, it does not support the Astra Pro. Only v1.x.x supports it.
