Re: USB Not Recognized in Virtualbox
Here's a quick checklist:
1. Are you using the proprietary version of Virtualbox or the open-source edition? The open-source edition does NOT have USB support.
2. Have you used the Virtualbox settings to actually turn on the USB support and allow it to "passthrough" that USB device?
3. Is the device mounted in the host OS? If so, it needs to be unmounted.
4. When I say "unmounted", I mean use the "Eject" or "Unmount" option. DO NOT use "Safely remove hardware" as this actually switches off the USB device.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
