USB external hard disk appearing disabled/greyed out
Posted: 17. Aug 2013, 11:51
(Please translate all the DOTs I write below into actual dots—getting hampered by the no-URLs-from-new-members policy.)
I've been doing a bunch of research including reviewing past posts and reading articles, e.g.:
I see four USB devices listed in the menu, two of which are grayed out, including the disk.
When I try to enable the Host Controller device (one of the non-grayed menu options), I get an error saying that it's in use.
I verified via support DOT apple DOT com/kb/HT5172#10 that I'm not using USB3 (instead on Hi-Speed i.e. 2.0).
I verified that the machine settings show USB and EHCI enabled.
I tried adding an all-blank filter (to the otherwise empty list) for shits and giggles.
I tried unplugging and re-plugging the disks.
Any other ideas? Happy to supply any additional info.
I've been doing a bunch of research including reviewing past posts and reading articles, e.g.:
- Googling "site:forums DOT virtualbox DOT org/ usb disk grayed | disabled | greyed mac host" (since forum search feature isn't as good and doesn't even admit the "usb" term as it's too few chars)
- davidoluwatimi DOT wordpress DOT com/2012/07/06/macosx-vbox-host-fix-ubuntu-usb-access/
- frank DOT heydlauf DOT de/jm2c/archive/80/virtualbox-on-os-x-host-howto-mount-an-external-usb-drive but super old and I'm not going to e.g. unload the host's USB kernel module
