utility downloads the specified mini-driver and firmware files to the specified
device.
.Pp
This utility will

work with Broadcom BCM2033 chip based Bluetooth USB devices.
The identification is currently based on USB vendor ID/product ID pair.
The vendor ID should be 0x0a5c
.Pq Dv USB_VENDOR_BROADCOM
and the product ID should be 0x2033.
.Pp
Due to copyright issues I will no longer provide mini-driver and firmware
files for the device.
These files can be obtained from the Linux BlueZ bluez-firmware package.
.Pp
