Read operation on device '2676:ba02:2:4:44' failed: 'The requested operation timed out.' : TimeoutException thrown (file 'PylonUsbDevice.cpp')

Question

I am using two basler acA1920-25uc camera and run it on Jetson Orin NX 16Gb and . In two days time, Consistently I am getting the following error. Read operation on device '2676:ba02:2:4:44' failed: 'The requested operation timed out.' : TimeoutException thrown (file 'PylonUsbDevice.cpp', line 778) in one of the two basler cameras The frequency of errors is not frequent. Do anyone know what is root cause to this error and how to fix it? PC : Jetson Orin NX 16GB (Seeed Studio) Connect Camera through USB3.0 Camera : Aca1920-25uc Cables : 2200000621 (basler cables) I measured the Jetson's parameters. However, almost all parameters are stable in voltage and current during camera errors. (VDD > 5V)
