Does the STM32F105 have a pull-up on USB_DP line? There is conflicting information in the USB hardware design guide (images from this design guide screenshotted below).

It's bug in that AN4879, the FS PHY used with the OTG module does have the DP pullup (as well as the pulldowns for host mode) see RM0008.

And 'F102/103 don't have the embedded pullup.

@Imen DAHMEN​ , can these please be fixed?

Thanks,
