I'm using the USB port in CDC with STM32F072 device. I'm using the F0 STM32Cube package version 1.5.0

At power up, if the device in not USB connected to a host, it goes in infinite loop in the USB_IRQHandler function and stall the main application execution: the LSOF ans ERR flag in the FNR register always pop-up. If I connect the device to host, the device is successfully detected and main application run as well. If I disconnect, no infinite loop in USB_IRQHandler function...

An idea to solve this problem?
