+Description:
+		Binary file containing the cached binary device object store (BOS)
+		of the device. This consists of the BOS descriptor followed by the
+		set of device capability descriptors. All descriptors read from
+		this file are in bus-endian format. Note that the kernel will not
+		request the BOS from a device if its bcdUSB is less than 0x0201.
