Google Glass on Windows7: cannot access device

Question

I have a brand new google glass and I tried to connect it to my Windows 7 PCs, but I cannot access the storage. If try the command adb devices, glass is not listed.

• I already installed the latest Google USB Drivers.
• Enabled Developer settings on Glass
• Glass is listed as "Android ADB Interface" in the Device Manager.
• If i connect glass to a Windows8 PC, everything looks good - so there shouldn't be problems with the cable or glass itself.
• I also tested to update the drivers INF file with the data listed in the device manager at "hardware ID" (as found in several solutions), but that didnt change anything.

I tested all these steps on two differnts PCs.
