This means I very much doubt you can get it properly into VirtualBox, not even when ‘auto-grab-usb’ is active. Or at least, I have never been able to do it from VMware. And WINE is out of the question completely.

So, find yourself a real Windows PC, or dual boot one. But not Virtual. The drivers work on XP and both 32 and 64 versions of Win7

This is how I got it to load the VCOM drivers in Virtualbox Win7-64bit in Debian Wheezy but probably works also for Ubuntu/KUbuntu/etc. I dont know if there are other issues I will run into later but finally got step one, the VCOM USB drivers recognized…..
NOTE: you must have installed “VirtualBox Extension Pack” otherwise you cannot pass the USB to the VM in Virtualbox.

1.) remove phone, shutdown, remove battery (do not connect until later)
2.) get MT65xx USB VCOM driver (for me usb2ser_Win764.inf), startup Win7 VM and add the driver to “c:\windows\inf” folder. Shutdown Win 7 VM.
3.) use “lsusb” to see what USB devices you have attached
4.) attach phone (do not turn on) and spam “lsusb”
5.) a new entry will be there, for me it was: “Bus 003 Device 010: ID 0e8d:2000 MediaTek Inc.”
6.) Unplug phone.
7.) go to Virtualbox, right-click your win7 VM: settings -> USB -> add empty filter
8.) fill in manufacturer field that you found with “lsusb” refresh, for me “Manufacturer: MediaTek”
9.) startup Win7 box and when system has loaded up and everything is at rest, attach phone (still off). You should see Windows search and load drivers VBOX USB etc. etc.
