Cannot connect to FLIR USB3 Vision camera ?

[justinbacle]

Hello all, just starting to use this rust lib as I am coming from python and the harvesters module (which is basically the equivalent of cameleon, but for python) but got sick of the snail pace of python.

My camera is as follows, (gathered from SpinView, before changing driver to libusb) :

DeviceDisplayName   Point Grey Research Blackfly BFLY-U3-23S6C
DeviceModelName         Blackfly BFLY-U3-23S6C
DeviceID            USB\VID_1E10&PID_3300&MI_00\9&10787E88&1&0000_0
DeviceType          USB3Vision
DeviceVendorName    Point Grey Research
DeviceInstanceId    USB\VID_1E10&PID_3300&MI_00\9&10787E88&1&0000
DeviceCurrentSpeed  SuperSpeed
DeviceAccessStatus  OpenReadWrite
DeviceVersion       FW:v1.9.3.00 FPGA:v2.02

Steps I did : Setup rust environment, tested that hello world worked. Installed libusb installed device driver with zadig Added dependencies to cargo.toml

[dependencies]
cameleon = { version = "0.1", features = ["libusb"] }

as specified in readme.md build the example script given in the readme.md

output:

on line

// Opens the camera.
    camera.open().unwrap();

Am I missing something obvious ?

Experiencing the same

[Inga-sunga-sun]

I got the same error in my environment.

OS: Windows10, Windows11 Camera: Basler USB 3.0 camera

[doc-E-brown]

I am able to successfully complete the tutorial on Ubuntu 22.04 with a Basler 45ucPRO camera, but for some reason I get the same error when trying to execute the same code in windows using WebUSB

called `Result::unwrap()` on an `Err` value: ControlError(Io(libusb error: pipe error

Caused by:
    pipe error))
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
