I got Fiio E7/E9 two days ago and like the combination very much. Unfortunately I have problems installing E7 in Windows 7 x64. Device manager lists "USB Audio DAC" among other devices but the driver is not installed (The drivers for this device are not installed. (Code 28)). I've tried a lot of things, nothing helped. I know this is not E7 problem, because it works just fine on my netbook with Windows XP Home.
Did anyone have such problems and solved them without reinstalling Windows ? Is there a kind soul who would post a screenshot of Driver tab for E7 from Device manager so that I can maybe select the driver manually ? That helped me with some other devices, but I cannot find the right driver for E7.
