It seems that USB device interface on my Tx2 dev kit have stopped working. - probably many more but these are the ones that make it difficult to use the Tx2…
As you can see from below: $lsusb and $lspci return nothing. Since this issue, I was able to re-flash the the Tx2 using the miniUSB port- thus indicating that the USB port, at least the miniUSB2.0, works. Strangely enough I was able to also ssh over Ethernet and run all software updates but I feel I have hit a road block trying to debug this issue. Mainly because shouldnt I see the network controller device when running $lspci.
Also the HDMI output works and when booting everything looks normal, i.e. nothing in the boot terminal fails.
