Sorry for the very late reply. Sometimes the info identifying the bridge chip is in dmesg. Otherwise I look up the USB numeric IDs on Google. This is for generic enclosures only. In my experience, the bridge on the 'complete' big-brand drives have their firmwares and device IDs modified for hide the chip's origin.
