Hi everyone.
I tried adding USB_OTG_FS/Virtual Port Comm to STM32F407VET6 as a device only, but the problem is that when I try to connect the STM32 USB to my PC/laptop, it says “USB not recognized” on my PC/laptop, and I think it might be a problem with the cable, but after I replaced the cable 5 times and tried connecting it to my laptop, the problem remained the same.
Where does this problem originate—in the code or the hardware itself?
I used two boards, and both experienced the same problem.
I replaced the MCU on the board with the original MCU.
thank you :)
