Subject: fix device id not working with g305

this uses w32 apis for enumerating dev info instead of ManagementObjectSearcher, which upper-cases dev ids, differing from kernel/cfgmgr32

this also breaks showing dev name alongside id, as the name seems inaccessible from cfgmgr32 given an interface supplied by rawinput

not a big deal considering the names are too generic to be useful anyway
