Good question. Some vendors mention the used USB bridge chip in the
specs, but apparently most vendors don't.

The USB host controller in the motherboard chipsets is unrelated to
The problem is the USB/(S)ATA bridge in the external enclosure. It must
be able to pass arbitrary ATA commands via (the SCSI commands passed
via) the USB bus. This is unfortunately vendor specific.
It should work with any motherboard chipset, except if its USB driver
filters the vendor specific command.
