Hello, I try to implement a dual cdc with two virtual port com on USB_FS and HS. Receives callbacks works well on both VCP but only transmit on the first VCP works. When I try to send data from the STM32 to the second VCP, nothing append.
OTG_FS_IRQHandler is endlessly called"signal handler called>() at 0xffffffe9"I have already increase the heap and stack size to 0x2000. I use the STM32H753i-EVAL2 board
