protdmag Posted March 28, 2016 Share Posted March 28, 2016 Hi All I'm trying to make a boot disk under ML and cant for the life of me get USB drives to mount. It did work at some point in the past but now nothing. When I connect the drives in VM I get a message about best host controller not being available. Once dismissed I can see the drive has connected and it shows up under OSX System Information (USB) but nothing in disk utility. Any help would be much appreciated, Its driving me nuts!
