Hello, as you probably know some USB devices (specially WWAN sticks like UMTS, LTE, CDMA) have "two-virtual-devices-inside": 1. ZeroCD - Virtual CD with x64/x32 driver for 2nd "main" device... 2. Main function like: LTE, UMTS modem or NIC card or ports etc. When such USB device is plugged ZeroCD is runned and main device is inaccessible until ZeroCD is ejected. (Driver installation app just ejects ZeroCD in the end.) So on the Windows ARM, ZeroCD with x64 and x32 driver is mounted and that's it. I even didn't know, that to access Modem/NIC function (without installing driver) I have to eject ZeroCD. Now I am seeking for CMD or VBS, what will run on ARM (EXE won't of course) to auto eject ZeroCD (so I can access Device Manager and update drivers). So is there any?
