Dear All.

I use STM32F205RCT6 and want to use VCP of USB HS-Core (PB13-15) with embedded PHY.

I wanted to use FS-Core (PA11-12) because I did and succeeded already.

But 64pin device doesn't include FS-Core.

I use VCP project of USB_Device_Examples in UsbLib V2.1.0.

Descripters (VID,PID,SERIAL etc) are not changed (0x0483,0x5740,...).

Then run the STM32, Connect to the WinXP 32bit by USB Cable.

Failure the Device installation at first.

But executing VCP_V1.3.1_Setup.exe installs driver,

finally ' STMicroelectronics Virtual COM Port (COMxx) ' was appeared in Device manager without any warning.

It can Open , Close , Tx , Rx , everything OK.

Next , Connect to Win7 32bit by USB Cable,

Failure the Device Installation at first.

But executing VCP_V1.3.1_Setup.exe installs driver,

finally ' STMicroelectronics Virtual COM Port (COMxx) ' was appeared in Device manager but with yellow warning (code 10).

It can not Open the 'warning' port...

Followings are declared in the project.

USE_STDPERIPH_DRIVER

USE_USB_OTG_HS

USE_EMBEDDED_PHY

Is it need to change the INF file FS-Core and HS-Core ?

Could any one solve this ?

Thanks

Dear All.

Can I ask following again ?

* CPU : STM32F205RCT6

* Module : USB HS-Core (PB13-15) with embedded PHY.

* Software : Virtual Comm Port of UsbLib V2.1.0.

* OS : Windows 7 32bit

* USB Driver : VCP_V1.3.1_Setup.exe

My result is that ' STMicroelectronics Virtual COM Port (COMxx) ' appears in Device manager WITH yellow warning (code 10).

I can not open this port.

Does anyone work well same as my condition ?

Thanks

I solve this problem by changingCDC_IN_FRAME_INTERVAL to 0 in usbd_conf.h , and now all work fine. Also i use this fix
