Hi,

I'm testing the demo on your website designed by itself.

STM32Cube_FW_F2_V1.7.0\Projects\STM322xG_EVAL\Applications\USB_Device\CustomHID_Standalone,

After the target code is downloaded to the board, the device manager displays as shown in the attachment.

it is mean that

Unknown usb device.

hi,Imen D,

 hpcd.Instance = USB_OTG_FS;

  hpcd.Init.dev_endpoints = 8;  hpcd.Init.speed = PCD_SPEED_FULL;  hpcd.Init.ep0_mps = DEP0CTL_MPS_8;  hpcd.Init.low_power_enable = DISABLE;  hpcd.Init.phy_itface = PCD_PHY_EMBEDDED;  hpcd.Init.Sof_enable = 0;  hpcd.Init.vbus_sensing_enable = DISABLE;

in my usb configuration.

D+ and D- are connected to the chip pin by external resistance?
