USB hub not working

cs-cam · 11-01-2005, 05:31 AM

My computer desk is a mess of cables, I have a large collection of USB powered devices and it was getting annoying tracing cables to find what was plugged into where. Today I received a shiny new externally-powered USB hub with the plan to make my workspace a tad tidier. I plugged it in, plugged all my devices in and booted up. It worked, I logged in, started X and used my mouse for a sec and everything seemed fine. Then I went out of the room to clear the table where I had just been working, came in and nothing worked. Weird, unplugged devices and no go. Unplugged and plugged in the hub and got some weird errors in /var/log/messages.log:

Code:

usb 3-1: new high speed USB device using ehci_hcd and address 8

usb 3-1: device not accepting address 15, error -32

So I reboot, no help. Remove power from the hub and plug it back in, same problem. Okay, so I figured I'd get sneaky and check /var/log/kernel.log from when i wasn't in the room, see what started this. So I did, and I can see all the devices starting up properly, looking good. At 20:46:27 I had just started X cause the nvidia driver had successfully loaded. Next message for me is at 20:54:42 and it's not very welcoming....

Code:

Nov  1 20:54:42 sylvester drivers/usb/input/hid-core.c: input irq status -71 received

That repeats itself like 20 times per second for a while. Then I get this:

Code:

Nov  1 20:54:57 sylvester drivers/usb/input/hid-core.c: input irq status -32 received

That last line repeats about 100 times and then I must come back and see there's something wrong and disconnect/reconnect the hub. This is the output for that:

Nov  1 20:54:59 sylvester usb 3-1: device descriptor read/64, error -32

And that's all I've got. All subsequent experiments just get the same output as in my first little code block. Anybody got any ideas what went wrong here? lsusb doesn't show the hub at all or any devices that are connected to it.

Thanks for any help

what does lshw show? what arch version? what kernel? With that info
ask at arch forum. Snowman was very helpful to me with Arch. Good luck.

Forgot to post my kernel version, I hate being dumb

At any rate, I've narrowed it down to the problem, sort of. I'm using 2.6.13-archck8. Now the weird thing is that this kernel has always worked fine for me. Now plugging USB stuff straight into the computer is giving me the same errors. I tried booting from Knoppix and wow, USB worked and the hub worked fine too! Booted from an Archie (Arch-based live CD) I had lying around and uh oh, USB problems again. Maybe it's something compiled into the Knoppix kernel by default that Arch doesn't have, I don't know. It's weird but I saved the output of lsmod in Knoppix, now I'm gonna boot Arch and compare

I had my case apart not long before this error and I was crapping myself that I'd shorted something in there, at least now I know my hardware is fine!
