Hi,

I am working with STM32G0B1CETx for an application as a replacement of STM32F105VCTx. I want to use to USB as Custom Human Interface Device Class. I am using CubeMx with MDK-ARM. I have configured USB_DRD_FS as Device_only_FS and Middleware section -> USB_Device i configured the same params as STM32F105VCTx for STM32G0B1CETx . 

When USB is plugged to Laptop STM32F105VCTx  recognizes device with  product string i have configured. but STM32G0B1CETx its showing Device Descriptor Request failed.
Any changes i missed? Can anyone help out?

Thank you

SPK

The MCUs are quite different so it is likely that you've missed some details.

Here you can find help with your STM32 project.

Then the situation is "something does not work on a custom board" :(  All bets are off.

Hi, 
In CubeMx when i configure device as HID Device it properly listed in My PCs device driver.
But when I change to Custom HID My PCs device driver is detecting device but showing driver error.

Just an update i saw. any way this can be resolved?

Then it can be just er.... a little bug in the code.

>  any way this can be resolved?

Someone should review the generated code and look for anything obvious, then debug. This way.
