I'm still trying to get these USB drivers installed.
I started up a VMWare virtual PC running 64 bit Win 7 and the virtual PC installed the drivers first time no problems.
The files listed in Device Manager for the G300 on the virtual PC are all present on my 'real' PC yet it fails to install.
If i point the Device Manager to my C:/Windows folder it says device recognised but specified file not found so that's better than the previous messages.
Anyway after some Googling i read a post that said that some people have problems with USB drivers if they have Logitech stuff installed...
I have a Logitech wireless keyboard and mouse- i wonder if that's the problem.
Can i be bothered to uninstall them on the off chance it might fix the G300 driver issue - and if it did fix it i'd have to get new non-Logitech keyboard and mouse.
Hmm it sounds like a big effort to me...
Do you have access to another computer that you could use? It should be literally a 10 minute job to get them installed. I think that's what I'd try. Let me know how you get on
