Hello,

    I'm trying to configure my usb driver to accept multiple possible vendor/product combinations. I found the component usb_report_filter, which as I understand consumes a usb devices report, and produces a usb configuration file with a matching policy and a report that my component can use to request the device. The report to my driver looks like this:

    <device label="usb-1-2" vendor_id="0xcf3" product_id="0x9271" bus="0x1" dev="0x2"/>
</usb_devices>

and it makes sense so my driver requests a device called "usb-1-2". The corresponding usb configuration is:

<config bios_handoff="true"><report devices="yes" config="yes"/>
    <raw>
        <report devices="yes"/>
        <policy label="wifi_drv -> usb-1-2" vendor_id="0xcf3" product_id="0x9271" bus="0x1" dev="0x2"/>
    </raw>
</config>

This seems like almost what I want, but somehow the <policy> node within the <raw> node seems to stop the driver from accepting this connection - I get a warning saying:

[init -> usb_host_drv -> usb_drv] Warning: no policy defined for label 'wifi_drv -> usb-1-2'

Am I using the component right? Is there a better way to do this? I followed the example in repos/ports/run/vbox5_genode_usb_hid_raw.run.

Thanks,

Colin
