Debug log goes here, should contain the backtrace, as well as the reset source if it is a crash.
Please copy the plain text here for us to search the error log. Or attach the complete logs but leave the main part here if the log is *too* long.

Other items if possible

• sdkconfig file (attach the sdkconfig file from your project folder)
• elf file in the build folder (note this may contain all the code details and symbols of your project.)
• coredump (This provides stacks of tasks.)

@nadeem268 Hi, please set the log level to verbose to print more logs.

And please try the basic host/usb_host_lib example to print the camera's descriptors.

There may be some compatibility issues in the descriptors processing stage in usb_stream

Hello sir !
please give me any solution

[leeebo]

@nadeem268 If host/usb_host_lib can not enum the device's descriptors successfully, maybe the device not support Full-speed.

[Nadeemranm]

Any other way to print device's descriptors, and which parameter will be change for half -speed support ?

[nadeem268]

What?
