I planned to use a vm for MT3620 development and installed windows 10 to my virtualbox with 50 GB storage and 8 GB memory but i could not connect the board to my vm succesfully. Could you please advice me about this issue? Here enclosed a screenshot from my device manager.
I am answering my self question. After a long investigation from the net i found below steps and now its working properly.
Step 1) Download and install the exact extension pack from internet for virtualbox to recognize the usb2.0 protocol. Because Azure Sphere devkit is running on usb2.0. Here is the web-site for download.
Step 2) Install the extension pack as next-next-next steps. [attachment=1]vbox_ext_pack_01.png[/attachment]
Step 3) Set the vm usb settings like below and boot the vm from virtualbox. After boot process wait near 2 minutes for self-installation of board drivers. Do nothing while it is installing the 3 com port drivers. Here is the below proper settings for vm. [attachment=0]usb_settings_for_vm.png[/attachment]
