USB appears to fail when the
UsbDeviceBuilderis called, regardless of what it is used for (serial, hid etc). The device gets stuck at this line and never goes over (does not panic, just gets stuck). Not sure if this is an issue withstm32f4xx-halor with usb-device, and it is happening only on nightly, all usb forms run fine on stable.Line that fails:
let mut usb_dev = UsbDeviceBuilder::new(&usb_bus, UsbVidPid(0x16c0, 0x27dd))
