[meta-ti] Beaglebone usb issue after first reboot

[Mark O'Donovan]

Issue:
Beaglebone black detects usb devices on first boot after flashing sd-card.
On subsequent boots it does not.

Setup:
Yocto Project 1.5.1
linux-ti-staging 3.12.17
meta-ti = "dora:990d8f62257029e25fc2b8786155bcf5dc483659"

Using the diff command found here:
http://superuser.com/a/470876

I found the following:
diff -r CLEAN-IMAGE/etc/udev/cache.data BOOTED-IMAGE/etc/udev/cache.data
0a1
> Linux version 3.12.17 (modonovan at changanu) (gcc version 4.8.1 (GCC) ) #3

Running the following after booting fixes the issue on the next boot:
echo "" > /etc/udev/cache.data

Is this a known issue??

Thanks
Mark
