Re: Galileo Debian v1.2 image

follow on: this morning I tried booting, let it sit for a bit and then just plug in USB hub: this time debug terminal showed a bunch of messages:

that started with:

For the fun of it, will now reboot and try different USB hub.  I remember a year or two ago, one of my other linux boards had problems with a specific USB hub, probably a long shot, but...

... Same messages...  As I said long shot...

However, I then plugged the USB2AX into it and it did show up as /dev/ttyACM0 likewise when I plugged in an FTDI cable, it added itself as: /dev/ttyUSB0

But again if I look at: dmesg | tail  I see

Tried again booting with hub plugged in, still hangs at:

...

It will probably continue to show some more messages after 2 minutes, and then hang again...
