One more question before I make a hub purchase: What is the largest number of ports supported (or recommended) for Linux?
I'd like to get one with more than four and have seen some with ten, but I wanted to make sure something like that would work.

The maximum number of USB ports would be 127. Then the USB address range is exceeded.

That's definitely the right answer. :P Linux fully supports the USB specification, so it's only limited by what USB is limited to.

That said, I don't think that will work, since the hubs take up addresses of their own. So, if you've got a setup with branching hubs, each providing 4, then you would need 42 of those addresses for hubs.

Computers get around this by having multiple root hubs.

Thanks, I have purchased a hub and it should be here sometime after the 1st.

So... Got the hub, but the Ethernet adapter is still not working, not even on my Windows 7 computer...
Does anyone know of a reliable Ethernet adapter for sale somewhere?

I don't want to purchase something that is going to be just another dead end.

EDIT: Purchased a Ethernet adapter on E-bay, should be here in a few days... (Think it was D-Link)

EDIT 2: This will likely (and hopefully) be the last technical assistance I request on this issue... I got the Ethernet adapter today, and it runs fine, as in it connects, is recognized, and transfers data.
However, when I run links I cannot navigate to www.google.com, I can only reach 192.168.0.1 (my router) and even then all it shows is something like "quest modem configuration".

To get this to work as it currently is I added the following to /etc/network/interfaces:

Code: [Select]
auto eth0
iface eth0 inet static
address 192.168.0.45
netmask 255.255.255.0
gateway 192.168.0.1

Any ideas. I know 192.168.0.1 is the router address for wireless access, is there a different method to connect with Ethernet?

I don't know the mechanics of Omnimaga and if editing a message bumps a topic. So just in case...

You don't get notified per mail but you will be notified if your in #omnimaga. (I think)

You need to specify a dns-server but it's easier with DHCP:
Code: [Select]
auto eth0
iface eth0 inet dhcp

#omnimaga doesn't provide notices for edited messages as far as I know. The "new" marker next to the topic will re-appear, but the topic won't get moved to the top of the topic list.

Hi, if this ends up posting, that will be pretty exciting. Has anyone ever posted on this topic from the nspire? Thanks for your help, Vogtinator, that worked.

P.S. This post is from the nspire!! :)
(reading the forum is kind of difficult, though...)

I assume there is no character map available in the default distribution...
That might be something Debian could be useful for. (don't know much about the available packages, though...)

Can anyone link me with a cheap powered USB hub that is known to work well?
Thankz :)

Any hub that is powered should work. USB is a very definiative protocol, so one hub is the same, protocol-wise, as any other.

i'm trying to use the keyboard on my Linux kernel but i can't -.- i type on the keyboard and nothing happens -.-
i will tell all that i've done:
1- i've downloaded the kernel (http://tiplanet.org/nspire-linux-builds/zImage_expanded_latest.tns) and rennamed it to "zImage.tns", i've downloaded the initrd (http://tiplanet.org/nspire-linux-builds/start_initrd.ll2.tns), the binary (http://tiplanet.org/nspire-linux-builds/linuxloader2.tns), the script (http://tiplanet.org/nspire-linux-builds/start_initrd.ll2.tns) and the ndless.cfg.tns edited with that line "ext.ll2=linuxloader2" (http://tiplanet.org/nspire-linux-builds/ndless.cfg.tns)
2-i've replaced the ndless.cfg.tns on my nspire touchpad non-cas.
3-i've created a folder named "Linux" on my nspire and i've send the zimage, initrd, script and Linuxloader
4- i've used Linux, all working good, just exploring, and today i tried to use the keyboard.
5- for use the keyboard i rebooted, connected the Nspire to a powered usb hub while in Nspire OS before running the bootloader, runned the initdr script, the Linux opened, i've connected the keyboarb to the powered usb hub but when i type nothing happens :s

what am i doing wrong?? :?

(sorry about bad english :/)

i don't understand this because i've done almost the same of this guy on the beggining of the video: http://www.youtube.com/watch?v=B2MiVkXhAYs, the only diferences are that i use the script wich adds that cmdline and my Linux have "nanocx login" instead of "buildroot login"
I'm Portuguese, sorry bad English

That's the bootscript again :P
But I think you downloaded it right, else it wouldn't boot at all.

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