Hi Guys,
Using Cube I configure STM32L053C8T6 for USB CDC and compile the code using Keil. Using Keil I flash the 32L0538DISCOVERY. On the PC side I installed VCP_V1.4.0. When plugging PC’s USB to “USB User� on the 32L0538DISCOVERY, Device Manager on PC would show exclamation marks instead enumerating device. Could you guys see what is wrong. Attached is Cube-Keil project and Device Manager screenshot. Regards
