Built 4.1-rc1 with config from https://github.com/Vogtinator/nspire-linux-configs/blob/master/kernel/devicetree.config

It boots but the problem remains: No device in sight on either dmesg nor lsusb 

tangrs, would you be so kind and post the .config you used? Just would like to rule out that there's something misconfigured in Vogtinators one

Mhmm.. Has anyone got usb working with the builds from http://tiplanet.org/nspire-linux-builds ?

Uname says 4.0.0-rc7-next-20150410, but my usb thumbkeys won't work for some reason. lsusb ends without any output, no reaction on dmesg and no new device in /dev either.. (doesn't matter whether I connect otg before or after linux  boot)

I can't guarantee that my otg adapter works (a little wonky construction), but it did with the old kernel and when pluggin it in while in Nspire OS it complains properly about a device connected it can't handle

lsmod end with "/proc/modules: No such file or directory"

If anyone wants a kernel build, I can make one when I have time.

If you happen to do so, could you enable cgroups please 
(Arch won't boot without it, but I reckon it would be nice on the nspire: Small, clean base to start from, fast package manager, prebuilt rootfs on archlinuxarm.org)

Also thought about doing it, but tangrs github repo is only legacy code. (and frankly I'm short on spare time right now ) Where would you take the code from, linux-next?

Is https://tiplanet.org/nspire-linux-builds/ updated?

I don't think so, at least with dtb version downloaded two days ago usb was still broken.

ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
usbcore: registered new interface driver usb-storage
usbcore: registered new interface driver usbhid
usbhid: USB HID core driver

I get the same + three additional ones (with the fresh downloaded kernel,initramfs,dtb):
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb

Could you try the new xconfig image? I switched from Xorg to KDrive/TinyX (or whatever it's called in buildroot) and everything should work fine.

Actually I can't... I have trouble getting USB to work

This means the OS doesn't recognize keyboard and usb-flashdrive. (But its not a hardware fault, tested it again with the old kernel). Went through menuconfig, the only suspicious things I found are:
#1 > Device Drivers > USB support > [* ]     Rely on OTG Targeted Peripherals List
If you say Y here, the "otg_whitelist.h" file will be used as a
  │ product whitelist, so USB peripherals not listed there will be 
  │ rejected during enumeration.

#2 [ ]   > Device Drivers > USB support >  [ ]  Generic EHCI driver for a platform device
is not activated, but it is in here https://github.com/Vogtinator/nspire-linux-configs/blob/master/kernel/.config
(used this to find a needed driver or something...)

But even with diabling #1 and enabling #2 it won't work 

I'm sorry to bother you guys again, but it just won't work for gods sake 

Here's exactly what I did:
$ PATH=$PATH+":/opt/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_EABI/bin/"
$ wget https://www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.14-rc2.tar.xz
$ unp linux-3.14-rc2.tar.xz
 <extracting without errors>
$ cd linux-3.14-rc2/
$ cp ~/Downloads/config ./.config   #This is your uploaded .config, verified it multiple times
$ export ARCH=arm
$ export CROSS_COMPILE=arm-none-eabi-
$ make silentoldconfig
 < ran through without a single error or question >
$ make -j2
......
 Kernel: arch/arm/boot/zImage is ready
$ ls -l arch/arm/boot/zImage
-rwxrwxr-x 1 simon simon 1504096 Feb 23 19:28 arch/arm/boot/zImage  #size comparison with prebuilt ones: small: 1753152 large: 1936000And no kernel messages again...

Both prebuilt zImages from here http://tiplanet.org/nspire-linux-builds/ boot as expected. (ok, the small one crashes midways with initrd, but hey - kernel messages )

I'm from Germany and was infected by the calc-virus in 7th grade when we needed a TI-82 STATS for school. I was very keen on TI-Basic, even remembered almost all entry-numbers of the program- and draw menus.. I wrote lots of programs, for cheating as well as for fun. Very simple ones like chat-programs (or TicTacToe against calc http://www.ticalc.org/pub/83/basic/games/strategy/tictactoe.zip) but also things like something cad'ish where you could build 3d objects from lines and then rotate, zoom and move them (sadly lost the code)).

After school I did an apprenticeship as an electrician for systems and devices (basicly most advanced electrician apprenticeship), but no graphical/programable calcs were allowed so I had to stick with some low level casio-garbage  Thus (plus the fact that I lost my Link-Cable somehow) the TI-82 didn't gain much interest anymore and I forgot just about everything over the years...

Then, a few months ago, I saw a video of a nspire running Linux. And a few days later someone sold his nearly unused TI nspire CX CAS for 100 euros in a forum I check regularly. So now I have a calculator running Linux which is insanely cool 

Only thing that bothers me is that it seems like I'm to dumb to compile a working Linux-kernel for nspire (http://ourl.ca/17131;msg=322933) and thats the reason for my todays registration
