Hmmm, USB and  Mac Mini - Not BFFs

I had a wee problem connecting a StarTech USB enclosure ( containing a 512 GB SSD drive ) to my Mac Mini this evening.


The drive never showed up in Finder, in Terminal ( under /Volumes ) or in Disk Utility.

Eventually, the enclosed would throw up a connection error.

In the logs ( sudo dmesg ) I saw: -

...

I tried various things, including suspending a running VM and shutting down VMware Fusion 8, but to no avail.

In the end, I moved the drive from one USB port to another.


( the arrow indicates the from, the connected USB cable indicates the to )

Strange but true ;-)
