That's the problem. The official drivers downloaded from AMD.com do not contain an entry for this AMD graphics card.
The card is an AMD Radeon HD 7570, and its full hardware ID is PCI\VEN_1002&DEV_675D&SUBSYS_2B221028&REV_00 .
Although the driver files contain entries for 3 other HD 7570's (entries # AMD6759.1,AMD6759.3,AMD675D.1), they're missing an entry for this particular subsys. All of the other 7570s use identical drivers (which, incidentally, is the same as for the 6570s), and this issue could be resolved as easily as adding two lines to the INF file:
"%AMD675D.2%" = ati2mtag_NI, PCI\VEN_1002&DEV_675D&SUBSYS_2B221028 (or even PCI\VEN_1002&DEV_675D)
AMD675D.2= "AMD Radeon HD 7570"
Alternatively, they could remove the "&SUBSYS_300017AF" from entry AMD675D.1, to the same effect.
