I have STM32L4 based board NUCLEO-L476RG
I have initialised it USB Device Only Mode with Mass Storage Class IP and a microSD Card interfaced on SDIO (1-bit) and from CubeMX.
I am using MSI RC at 48MHz to clock USB.
Based on this example, I have made all the necessary modification in usbd_storage_if.c file.
I am able to get the USB enumerated on the PC when I connect the USB cable, the device appears in Unspecified category.
No new removable drive appears in the system window.
I have checked all the blogs I could and I have gone through the UM1734 User manual STM32Cube USB device library for more than 2 weeks
I have implemented a mouse before this and as well with the same sd config I have initialised FatFS on SD Card I didn't face any problem so I don't think there's some hardware issue.
Any help ?
How can I debug or if something more needs to be done?
Thanks & regards
