onec time check ,i made a mistake. PCI\VEN_1095&DEV_3112&SUBSYS_61121095 exists indeed. bwt,i've a Q: in txtsetup.sif we assign such hwids of 3112 as 3112R ,and don't add the 3112 driver. but we do'nt add such 3112 hwids to 3112R.inf,so when GUIsetup,how system scan and install right driver? keep on using 3112R.sys came from txtmode?
