Hi all
When "should" a USB device (an Icybox JBOD 4 bay DAS in this case) power
down? Most (ymmv) USB devices (keyboards, mice etc) are powered from the
host if they're not powered from a powered hub. Last night, in response to
the recent samba vulnerability [1], I patched then powered down my media
server. I left it off overnight as I was too tired to do any sort of
testing.
This morning, it wouldn't boot to GUI and the logs were telling me it was a
USB device fault. Turns out the Icybox (whose drives are referenced in the
server's /etc/fstab) was off. Powered the Icybox back up, rebooted the
server and all is well.
However the Icybox has its own power supply. So I'm wondering why (when it
doesn't have any settings/ drivers - the only controls on the front are for
fans) - does the unit power down? Is there anything I can do about it -
I've never been too hot on low level device handling in Linux.
Cheers
Rob
