/proc/bus/usb is empty

Dusty · 2004-07-14 01:03:52

I knew I wasn't cut out for this posititon... a dev posting in Newbie Corner, that's bad publicity. I'll take full and sole responsibility for my ignoance!

Anyway, I'm setting up Arch on my parent's computer and am having trouble with the USB printer. I got the parallel port printer going, no problem, but thd system doesn't seem to be recognizing the USB devices.

/proc/bus/usb/devices doesn't exist like it should and /proc/bus/usb is empty. I don't have hotplug enabled, I want the printer detected on startup.

On my personal system, I didn't have to do anything for it to recognize my USB mouse, so I'm not too sure what I'm looking at.

Here's some info:

and the problem:

$ ls /proc/bus/usb -a
.  ..

Am I missing something simple, or am I in for super headaches?

libusb is installed, kernel is 2.6.7. It worked fine under Mandrake.

Thank ye,
Dusty

do you have libusb installed?

normally i would load usblp via rc.conf but i forgot to put the module in the list. despite my error i still get the module autoloaded somehow. i assume it is some combination of libusb and hotplug packages (thought i do not start hotplug at boot).

The problem was an unloaded module, ohci-hcd. I scaned the /lib/modules directory for possible names of modules to be loaded and that one rang a bell. All fixed now, until I start messing with messy hotplug...

Have you installed udev yet? You can't throw devfs at your ma!

Dusty · 2004-07-14 17:36:33

I'll install udev when Arch officially supports it. I like to be running exactly what Arch expects, both because neither me nor Arch will be surprised that way and because then I know what to document...

Dusty

xerxes2 · 2004-07-14 21:14:22

oki, but it can fail , I know.....
devfs is doomed, that's how I understand it! :?

sarah31 · 2004-07-14 21:25:09

arch officially supports it now
so how about the migration docs eh?

Xentac · 2004-07-14 21:33:01

Arch has a package for it. Currently there are no init script modifications, so it's not a drop in replacement.

xerxes2 · 2004-07-14 21:35:09

Even polar bears can understand the Migrate to udev for dummies step by step process.

There is one little detail I wonder about and that is the first line in lilo.conf , maybe I should change it?

cs25x · 2004-07-14 21:49:39

why not get it working with hotplug first & then figure a kludge?

usb & devfs are real strange. e.g. I have camera which can only be mounted if usbfs is turned off while devfs starts. However to use it as a webcam, it needs usbfs. So I more or less have to start devfs and then mount usbfs. It still gives trouble, but it gives me usbfs and the hotplug camera.

How do you get to be a polar bear?

If your parents are polar bears and they... you know... and have a kid, and you're that kid, you'll be a polar bear.

bah that invovles manual tasks on my part. once it is in "drop in" state then i will do that. i don't want to do developers work. i'm freaking lazy or did you forgit?

cs25x · 2004-07-14 23:44:16

I will have to check my parents.

Xentac · 2004-07-15 00:37:49

It's doubtful that udev will ever be a drop in replacement. There are too many things that need to be worried about. Like fstab, lilo.conf/menu.lst, etc.

We'll make it as easy as possible, but if you screw it up because you weren't thinking, it's your own damned fault.

I know what the ransom notice is too, I just know it! I'll never see this thread again until I pay it. Yes, that's right! I have to write some docs!

Ok folks, here's what I'll be working on during Christmas break when I have some free time... no, I honestly hope it will be sooner:

HOWTO patch files in ABS
Devland:
why we don't have Bz2
why we don't have diffs
Judd's never ever ever going to release Arch 0.7, SO THERE
Updates to the XOrg wiki howto
gensync man page

I promise I'll do that. Can I have my thread back now? pleeeeeeeeeaaaaaaaaaasssssse?

Not that I know what I'd do with it if I had it. Come to think of it, this thread is a brat. keep it.
