Possibly related to #5502
Feel free to close for that issue if so

Version 0.2.281 but its been happening for a while

[bjorn3]

product is resolved to Iterator::product.

@jacobrosenthal are you still experiencing this?

UsbDeviceBuilder seems to define some of its methods through a macro, but not manufacturer or product, so I'm not sure that's the problem.

[jacobrosenthal]

Yes though Theres another example alongside that one called usb_poll.rs that doesnt put the UsbDeviceBuilder in a Some (within an unsafe block) that is fine,

    let mut usb_dev = UsbDeviceBuilder::new(&usb_bus, UsbVidPid(0x16c0, 0x27dd))
        .manufacturer("Fake company")
        .product("Serial port")
        .serial_number("TEST")
        .device_class(USB_CLASS_CDC)
        .build();

But not

    unsafe {
        USB_SERIAL = Some(SerialPort::new(&bus_allocator));
        USB_BUS = Some(
            UsbDeviceBuilder::new(&bus_allocator, UsbVidPid(0x16c0, 0x27dd))
                .manufacturer("Fake company")
                .product("Serial port")
                .serial_number("TEST")
                .device_class(USB_CLASS_CDC)
                .build(),
        );
    }
