mirabox Linux kernel 3.2.36 suddenly missing xhci
« on: 12 February 2015, 08:36:05 pm »

Hi,

I have something very weird on my Mirabox.
Suddenly the external USB ports stopped working on Debian Wheezy.

I booted on the rescue disk and they worked again. So it isn't a hardware issue.
But back on my Wheezy with kernel 3.2.36, still no external USB.
Digging deeper lead me to notice that kernel messages (kern.log) are missing "hci_hcd 0000:01:00.0: xHCI Host Controller" messages.
Comparing with older logs I see the xhci messages.

I'm using the stock kernel and didn't modify anything. Kernel has not been changed. And all modules are compiled inside the kernel.
