Yes, the Pro Dual CompactFlash Adapter supports UDMA 7 CompactFlash cards in UDMA 6 mode.

Background: CompactFlash Revision 6.0 (November 2010) added UltraDMA Mode 7 (167 MB/s), which is up to 20% faster than UDMA 6 (133MB/sec). All UDMA 7 CompactFlash cards are compatible with UDMA 6 cameras and readers.
 
708 I cannot read 64GB or 128GB CF cards in WindowsJan-07-14
This is a Microsoft Windows driver bug with some 64GB CF cards. Sonnet is working with Microsoft to resolve this issue. (64GB and 128GB CF cards work fine with Qio and Qio-CF in OS X.)

A partial list of cards Sonnet has tested:
Patriot Pro CF 266x 64GB/128GB card is recognized under Windows
Lexar Pro 1000x UDMA 7 64GB/128GB card reports itself as 32GB
SanDisk Extreme Pro UDMA 6 64GB/128GB card reports itself as 32GB
