    Subjectfile2alias - incorrect? aliases for USB
    Date
    file2aliases puts in alias device ID high and low numbers directly from match 
    specifications. E.g. for this match table entry:

    usb-storage 0x000f 0x04e6 0x0006 0x0100 0x0205 ...

    it generates alias

    alias usb:v04E6p0006dl0100dh0205dc*dsc*dp*ic*isc*ip* usb_storage

    unfortunately real device attribute does not include high and low - rather it
    has single device ID (as part of PRODUCT) that should be contained in these
    bounds:

    length += snprintf (scratch, buffer_size - length, "PRODUCT=%x/%x/%x",
    usb_dev->descriptor.idVendor,
    usb_dev->descriptor.idProduct,
    usb_dev->descriptor.bcdDevice);

    or bcdDevice file in sysfs.

    This makes those aliases rather useless for the purpose of matching reported
    device. It may take the same route as PCI and reject all device ID table
    entries that have High != Low but there are quite a few of them available.

    I am rather confused because I do not see how this condition (low <= bcdDevice
    <= high) can be expressed using simple glob pattern (unless we are going to
    take glob library from Zsh :)

    thank you
