Could you see some messages?

no -.- i open the Linux and when appears "nanocx login:" i connect the keyboard but nothing happens -.- i try to type and nothing happens before or after I write "root" on the login

Could you post the output of "lsusb"(all lines) and "dmesg"(the lines that seem relevant)?

the lsusb command i use it but nothing happens

If the login appears, that means that it worked. The keyboard may not work, I found that kernels that worked with initrds did not work with usb, and kernels with usb did not work with initrds. When it says "nanocx login", try typing root for the username on the calculator keypad, and that should work.

(actually I have quite a few more than this, but I don't feel like making bars for them all.)

yes i've done it and the keyboard still don't work -.- and i tried with 2 keyboards -.- a wireless keyboard and a normal keyboard

Could you post the output of "lsusb"(all lines) and "dmesg"(the lines that seem relevant)?

related to "dmseg" command, i can put some lines (the "(...)" repesents that numbers):
(...)RAMDISK: bzip2 image found at block 0
(...)EXT4-fs (ram0):couldn't mount as ext3 due to feature incompatible
(...)EXT4-fs (ram0): mounting ext2 file system using the ext4 filesystem
(...)EXT4-fs (ram0): mounted filesystem without jornal. Opts:(null)
(...) VFS: Mounted root (ext2 filesystem) readonly on device 1:0
(...)devtmpfs: mounted
(...)freeing init memory: 136k
(...) EXT4-fs warning (device ram0): ext4_update_dynamic_rev:764: updating to ver 1 because of nex feature flag, running e2fsck is recommended
(...)EXT4-fs (ram0):re-mounted. Opts: errors=remounted-ro

Really? Mine works fine with both.

The dmesg output seems right, but lsusb should definitely output something relevant.
Could you try to unplug the hub before booting and plugging it in after it's booted?
Do you have a powered usb hub (which you need)?

If TI's OS doesn't recognize the hub it's not supported.
Maybe you can try another one?

Link is here

wait, how it is supposed to be the notification?
i don't have another hub, this one isn't mine, asked to borrow it for this purpose and it works perfectly on pc.
the kernel that i'm using is the last one, the expanded, "Success at 20130211_0728 for version v3.6-26201-g341712f, config expanded: zImage_expanded_20130211_0728.tns", wich one should i try?

You can try the next expanded version.
The defconfig kernels may work, too, but I don't know
whether USB keyboard support is enabled.

I recommend naming this flavor of Linux "TangriNe" :)
I am trying this today on my new CX CAS

On a scale of Ubuntu to "barebones core with no hardware drivers or configurations", how user friendly is this Linux port?

the latest defconfig simply crashes on my ti-snpire touchpad (with the CAS system using nlaunch), i tried twice open Linux using the initrd script but it crashes on a line that says:
r4:000000000000 r3:000000000
(the number of characters "0" is not right)

As to the USB issue, did you try the workaround on the Wiki? There's a bit of weirdness with USB host.
