Jessie (snapshot) image 2014-10-08 missing kernel sources + and BBB not recognized by computer

I just flashed the 2014-10-08 jessie snapshot as it comes with pre-loaded SGX kernel modules and I wanted to try lxqt.
But however my computer doesn’t recognize the BBB (as a removable device) when I connect it through USB. ( I installed all the drivers etc.)
This problem only occurs with jessie I guess. Does it have to do with the USB networking thing?
I checked the dmesg log for a line containing ‘rndis’ but it didn’t show any, so I guess I have to edit the kernel sources. (basically following this tutorial → http://elinux.org/BeagleBone_Usb_Networking)

How am i supposed to be editing the sources if there isn’t anything in /usr/src/ ?

Well the "usb-flash" drive should be working out of the box. so
something must have happend when you tried to flash the eMMC.. you did
let it flash the eMMC right?

Last week i posted a newer build (2014-10-22):

http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot

But i forgot udchp, so usb-networking doesn't work, until your run:

sudo apt-get update
sudo apt-get install udhcpd

That's fixed for whenever i do the next snapshot:

/usr/src/ ?

I made it dirt easy:

git clone https://github.com/beagleboard/linux
git checkout `uname -r` -b tmp

config is "bb.org_defconfig"

Regards,

Many thanks!

Does the newer build have SGX modules or do I have to do:

sudo apt-get install ti-sgx-es8-modules-uname -r
sudo depmod -a uname -r
sudo update-initramfs -uk uname -r

everytime I upgrade to a newer TI kernel or flash a newer jessie build?

Correct, "everytime" you upgrade the kernel.

The bits are here if you want to do it differently:
