Unsuccesful attempt due to connection lost

[joopdo]

Bose Device: QC35II
Updater machine: Ubuntu with virtualbox Windows 10 with USB connected

Update process works like a charm, I can select 3.18 but once I get the progress bar, it always stops at 10%. After a while things timeout and I need to start over. I suspect this has to do with me using a Linux machine with Windows 10 as a virtual machine, or perhaps I should try a different version to update.
Note, when I unplug and replug the USB, it does get connected straight to Windows machine every time.

I think you are right. I think the earphone will reboot during the update process, and so the USB connection will be lost once or twice during the update.
