Log from #neuros IRC channel

can someone help me with my problems getting my neuros to mount on linux...have the proper fstab entries and everything....i upgraded my distro (mepis) and now it's not working leading me to believe that my neuros is not showing up at the same location (which was /dev/sda1)

[05:36]

as root... cat /proc/scsi/scsi

[05:37]

also as root... lsmod

[05:43]

sorune: will do

[05:43]

root@3[yonkeltron]# cat /proc/scsi/scsi

Attached devices:

oh wait...

one sec

not plugged

sorune: still nothing in in /proc/scsi/scsi

[05:45]

sorune: i just need to figure out what device the neuros is now. if it's not sda1 that is, what is it?

[05:47]

<iswm>

yonkeltron, ub* maybe?

[05:48]

[Chameleon]: good call

[05:48]

iswm: yeah that's what dmesg hinted at but there are no ub* in my /dev

[05:49]

<iswm>

You can always ls /dev, then plug in the neuros, then ls /dev again and see if anything got added.

[05:49]

<iswm>

That's what I had to do.

[05:49]

iswm: ok...let me try

[05:50]

iswm, sorune, [Chameleon]: relevant bits of dmesg: usb 1-7: new high speed USB device using ehci_hcd and address 8

[05:50]

uba: device 8 capacity nsec 78140160 bsize 512

[05:50]

uba: device 8 capacity nsec 78140160 bsize 512

[05:50]

uba: uba1

[05:51]

<DeepB>

i'd rather rmmod ehci_hcd

DeepB: ummmmmmm?

sorune: anything?

iswm: no difference

<iswm>

Interesting

[06:00]

<iswm>

What kernel version?

[06:00]

<DeepB>

yonkeltron: get rid of ehci_hcd, and load sd_mod

[06:00]

iswm: 2.6.10

[06:01]

iswm: maybe it's not compiled right.....i can always recompile with a different set of options

[06:01]

* SmrtJustin forgets what usb driver he uses

[06:01]

DeepB: is that safe and if so...how do i do it?

[06:01]

SmrtJustin: glad to see u mate

[06:01]

yonkeltron: I noticed you kept trying to get ahold of me

[06:02]

SmrtJustin: yeah. thanx for being here.

[06:02]

well i gotta go to bed, but I guess I could stay 5 mins

[06:02]

does any of your usb drivers work?

[06:02]

devices**

[06:02]

sorune wishes he had a neuros to plug in right now

[06:03]

SmrtJustin: yes....my mouse works fine.

[06:03]

you never fixed that sorune ?

[06:03]

<iswm>

Hmm..

[06:03]

<iswm>

usb 1-4: new high speed USB device using ehci_hcd and address 9

[06:03]

<iswm>

uba: device 9 capacity nsec 117210240 bsize 512

[06:03]

<iswm>

uba: device 9 capacity nsec 117210240 bsize 512

[06:03]

<iswm>

uba: uba1

[06:03]

sdb1 ?

[06:03]

<iswm>

Working fine here, strange.

[06:03]

<unknown_lamer>

wait, is that the Neuros?

[06:04]

iswm: yeah but do u have a /dev/uba1?

[06:04]

<iswm>

yonkeltron, sure do

[06:04]

<unknown_lamer>

kljsdlfkjsldjj woah, so usb mass storage devices work without scsi now?

[06:05]

yonkeltron: did you try taking the brain of the neuros and just plugging the backpack in?

[06:05]

SmrtJustin: yeah. that's how i've been doing it the whole time. u taught me that ages ago

[06:05]

<DeepB>

yonkeltron: lsmod | grep ehci_hcd if not there, you'll have to recompile and make it as a module, or disable it, usually (u|o)hci works better for the neuros, also try to load sd_mod if not there, you'll have to recompile

[06:05]

<unknown_lamer>

yonkeltron: are you running udev?

[06:05]

lol, I usually dont do that, but its a good thing to try

[06:05]

I dont do it out of pure lazyness though

[06:06]

<unknown_lamer>

DeepB: you do not want to disable EHCI_HCD

[06:06]

<unknown_lamer>

DeepB: because OHCI/UHCI is USB 1.1, EHCI is 2.0. Unless you want to spend 17 hours on 20G of music at least...

[06:06]

unknown_lamer: udev?

[06:06]

<unknown_lamer>

yonkeltron: ps aux | grep udev

[06:07]

<unknown_lamer>

yonkeltron: it manages /dev

[06:07]

<DeepB>

unknown_lamer: hummm... mine does not work if it's there laying in the middle

[06:07]

I have both OHCI and EHCI

[06:07]

try using both

[06:07]

<unknown_lamer>

SmrtJustin: right, ohci is your 1.1 controller and ehci is the 2.0

[06:07]

oh

[06:07]

<unknown_lamer>

SmrtJustin: the kernel does everything automagically (since every ehci controller has an ohci subcontroller)

[06:07]

do if I dont load ohci then usb 1 wont work?

[06:08]

<unknown_lamer>

SmrtJustin: basically

[06:08]

but 2 is compatible w/ 1

[06:08]

so why do I even need OHCI?

[06:08]

<unknown_lamer>

Because the EHCI controller has an OHCI sub controller.

[06:08]

so then I dont need to compile OHCI?

[06:08]

<unknown_lamer>

USB 2.0 is backwards compatible because it has a USB 1.1 controller.

[06:08]

<unknown_lamer>

You do.

[06:08]

oh I do

[06:08]

<unknown_lamer>

basically the EHCI controller looks like this:

[06:09]

see I was confused about this when I compiled my kernel, so I enabled them both

[06:09]

<unknown_lamer>

ROOT -> (1) OHCI -> (2) (usb 1.1 stuff) |-> (1) real USB2 stuff

[06:09]

<unknown_lamer>

so it physically has an ohci controller connected to it

[06:10]

so first, it sees if its usb 1 w/ ohci, then if its 2 it passes it to ehci?

[06:10]

<unknown_lamer>

no, it sees ehci first.

[06:10]

<unknown_lamer>

when you plug a usb device in

[06:10]

<unknown_lamer>

the kernel asks it what it supports

[06:10]

<unknown_lamer>

and it'll pop back whatever version of usb + the kind of device it is

[06:10]

unknown_lamer: so should i apt-get it if i don't have it?

[06:11]

<unknown_lamer>

yonkeltron: no.

[06:11]

yonkeltron: its a kernel module

[06:11]

<unknown_lamer>

yonkeltron: lsmod | grep usb_storage

[06:11]

<iswm>

Well time for sleep, I take the first part of a test the determines if I graduate or not tomorrow. Good luck, yonkeltron.

[06:11]

<unknown_lamer>

SmrtJustin: udev is not a kernel module

[06:11]

oh, sorry I thought you were talking about the ehci and ohci w/ him too

[06:11]

<unknown_lamer>

yonkeltron: is the usb_storage module loaded?

[06:11]

<unknown_lamer>

clinton@drizzlehell:~$ lsmod | grep usb_storage

[06:11]

<unknown_lamer>

usb_storage 31616 0

[06:11]

<unknown_lamer>

usbcore 117496 7 tiglusb,ehci_hcd,usb_storage,usbhid,hci_usb,ohci_hcd

[06:12]

iswm: just remember to answer "C" unless the answer was already "C" twice in a row

[06:12]

<unknown_lamer>

it should pop something like that back if you run that

[06:12]

<unknown_lamer>

solomonn: if the test is scantron and made by a human being there is a higher chance that the answer is C

[06:12]

unknown_lamer: it wont if usb_storage is compiled into the kernel

[06:12]

<unknown_lamer>

solomonn: I forgot how much more

[06:12]

<unknown_lamer>

hrm

[06:12]

iswm: and if you don't know the answer to an essay question just state the most interesting thing you know

[06:12]

unknown_lamer, SmrtJustin: not loaded

[06:12]

<unknown_lamer>

yonkeltron: ok

[06:12]

<unknown_lamer>

yonkeltron: dmesg | grep usb-storage

[06:13]

ahh, your smart unknown_lamer

[06:13]

usbcore: registered new driver usb-storage

[06:13]

<unknown_lamer>

SmrtJustin: or ... usb-storage: device found at 11

[06:13]

unknown_lamer: here

[06:13]

root@3[yonkeltron]# dmesg | grep usb-storage

[06:13]

usbcore: registered new driver usb-storage

[06:13]

<unknown_lamer>

yonkeltron: and that is it?

[06:14]

unknown_lamer: yep

[06:14]

you have the neuros plugged iN?

[06:14]

<unknown_lamer>

yonkeltron: plug the neuros head back in, turn it on, and then plug it in to the computer

[06:14]

<unknown_lamer>

yonkeltron: when the sync animation starts run dmesg | grep usb-storage again

[06:14]

unknown_lamer: gotcha

[06:14]

once i wrote an english comp. essay questioning the validity and import of the essay question, and it worked

[06:14]

wait a few secs after the sync animation...

[06:14]

but it was just

[06:14]

er

[06:14]

mine doesnt register till like 5 secs after

[06:14]

<unknown_lamer>

solomonn: the essay is overrated

[06:15]

but it was just some state standardized test thing anyway

[06:15]

<unknown_lamer>

The structure is so ... limiting

[06:15]

<unknown_lamer>

intro

[06:15]

<unknown_lamer>

topic topic subtopic subtopic ...

[06:15]

<unknown_lamer>

conclusion

[06:15]

<unknown_lamer>

and you can do that for hundreds of pages.

[06:16]

<unknown_lamer>

a recursive tree of essays

[06:16]

unknown_lamer: same thing...and it stil won't mount

[06:16]

unknown_lamer: for mine i wrote a narrative of an experience i had, at the end of which questions like the one I had been asked seemed very small to me

[06:16]

unknown_lamer: can't remember the question though :)

[06:17]

yonkeltron: but what does the output of: dmesg | grep usb-storage say?

[06:17]

unknown_lamer: i guess that proves that it really was a useless question :)

[06:17]

<unknown_lamer>

yonkeltron: dmesg | tail

[06:17]

[06:18]

* SmrtJustin thinks its udev of devfsd's fault

[06:18]

unknown_lamer: there is no /dev/uba1

[06:18]

<unknown_lamer>

hrm

[06:18]

<unknown_lamer>

ok, cd /dev

[06:18]

unknown_lamer: not anywhere on my system.....

[06:18]

well I gotta go to bed

[06:18]

<unknown_lamer>

do whatever you do to become root

[06:19]

night

[06:19]

<unknown_lamer>

and then

[06:19]

<unknown_lamer>

/dev/MAKEDEV uba1

[06:19]

yonkeltron: hope you get it work working, keep me posted

[06:19]

SmrtJustin: thanx man!

[06:19]

oops

[06:19]

unknown_lamer: /dev/MAKEDEV: don't know how to make device "uba1"

[06:19]

<unknown_lamer>

hrm

[06:20]

<unknown_lamer>

ok, ls /dev/ide

[06:20]

<unknown_lamer>

yonkeltron: actually can you ls /dev

[06:21]

<unknown_lamer>

yonkeltron: and then privmsg me the output?

[06:21]

<unknown_lamer>

yonkeltron: I think you might be running devfs which screws up all the names

[06:23]

<unknown_lamer>

yonkeltron: ok, it looks like you aren't running devfs or udev

[06:23]

<unknown_lamer>

yonkeltron: apt-get install udev

[06:23]

unknown_lamer: ok so?

[06:23]

<unknown_lamer>

yonkeltron: i.e. none of your devices are created automatically by hotplug

[06:24]

<unknown_lamer>

yonkeltron: install udev and reboot

[06:24]

<unknown_lamer>

yonkeltron: that should fix everything

[06:25]

unknown_lamer: it can be apt-get'd?

[06:25]

<unknown_lamer>

yep

[06:25]

<unknown_lamer>

yonkeltron: apt-get install udev

[06:25]

<unknown_lamer>

yonkeltron: you may not have to reboot

[06:26]

<unknown_lamer>

yonkeltron: just run /etc/init.d/udev start

[06:26]

<unknown_lamer>

yonkeltron: after apt-get ing it

[06:26]

unknown_lamer: good. i have a decent uptime

[06:26]

unknown_lamer: k....working

[06:27]

kind of on-topic: anybody know why devfs is taking over

[06:28]

<unknown_lamer>

sorune: if it is enabled in the kernel and set to automount on boot it will always own /dev

[06:28]

<unknown_lamer>

sorune: you have to recompile and disable it entirely

[06:28]

ah, so Linus likes it

[06:29]

<unknown_lamer>

No, he hates it

[06:29]

<unknown_lamer>

it is deprecated and will be removed when 2.7 forks

[06:29]

<unknown_lamer>

udev is the new solution. It runs in userspace and is really nice.

[06:29]

sweet, i hate it too :)

[06:29]

unknown_lamer: there will be a fork?!?!?!

[06:29]

<unknown_lamer>

sysfs + hotplug + udev

[06:29]

<unknown_lamer>

yonkeltron: the dev and stable trees...

[06:30]

<unknown_lamer>

yonkeltron: it's not a fork-fork

[06:30]

branch

[06:30]

<unknown_lamer>

yeah

[06:30]

unknown_lamer: oh...not like the ones on slashdot....damn gossip posters

[06:30]

<unknown_lamer>

haha

[06:30]

<unknown_lamer>

the HURD is the FUTURE

[06:30]

<unknown_lamer>

l4hurd can boot now

[06:30]

<unknown_lamer>

and you can set the initial fs translator with GRUB to be "Hello World"

[06:30]

it is the best acronym so it has to win

[06:30]

<unknown_lamer>

but stuff like the memory management server don't work :)

[06:30]

<unknown_lamer>

but damn is it amazing that it even gets that far

[06:31]

<unknown_lamer>

because that means that sigma0 and stuff are done

[06:31]

unknown_lamer: ok here i am.......let me try again

[06:31]

<unknown_lamer>

which is a HUGE accomplishment

[06:31]

<unknown_lamer>

alright

[06:31]

is it actually a better suited design than linux

[06:31]

<unknown_lamer>

maybe

[06:31]

<unknown_lamer>

we'll find out

[06:31]

unknown_lamer: i remember when hurd was only a joke...oh wait....

[06:31]

maybe someday we will :)

[06:31]

<unknown_lamer>

it is way more flexible

[06:32]

<unknown_lamer>

solomonn: nah, marco is years away from graduating and I think he is doing Hurd stuff for his graduate thesis

[06:32]

<unknown_lamer>

and another guy is rewriting parts of the Hurd in C++

[06:32]

<unknown_lamer>

for his thesis

[06:32]

<unknown_lamer>

C++ is the DEVIL

[06:32]

<unknown_lamer>

it should be done in Lisp

[06:32]

unknown_lamer: i imagine many people have worked on hurd for their, uh, theses :)

[06:32]

<unknown_lamer>

solomonn: it's a research project for now

[06:32]

write the hurd in python

[06:32]

hehe

[06:32]

<unknown_lamer>

solomonn: which is a good thing because it is doing stuff no one has done before ... if we pretend plan9 didn't exist

[06:33]

<unknown_lamer>

except plan9 didn't go as far as Hurd

[06:33]

unknown_lamer: ok i plugged in the neuros with no brain and it's a solid light.....amber that is. mount /mnt/neuros now yields: mount: special device /dev/sda1 does not exist

[06:33]

<unknown_lamer>

yonkeltron: dmesg | tail ?
