Hi Dave,
I have the same problem (and almost the same laptop, Thinkpad T430
here), all external USB ports without power - even the always-on one
:-).
The bug seems to be ACPI related, I bisected it down to this patch:
f95988d ACPI / scan: Treat power resources in a special way
In the dmesg I have some error like these:
ACPI: Power Resource [PUBS] (on)
...
pci 0000:00:14.0: System wakeup disabled by ACPI
for the USB controllers in the broken kernel, there are some in your
dmesg too. I'll try to come up with a fix for current mainline, but all
the acpi stuff is quite obscure to me and the patch does not revert
cleanly, maybe Rafael (in CC) has some idea!
Fabio
