 Posted: Thu Dec 04, 2003 2:02 am Post subject: USB devices suddenly stopped working |
 |
|
All of my USB devices stopped working about a week ago. I'm still not sure what I changed to cause this, but I cannot figure out how to fix it. I've gone through my kernel config and checked to make sure everything USB-related that is needed is there. Output of cat /proc/bus/usb/devices is empty, while i get the following from cat /proc/bus/usb/drivers
| Code: |
cat /proc/bus/usb/drivers
usbdevfs
hub
hid
0- 15: usblp
usb-storage
|
USB devices that should be connected are an external hard drive, hp printer, and mouse. They all worked prior to whatever happened last week.
Any suggestions on where I can go from here? |

do you have your usb stuff compiled as modules?
what does lsmod say?
what does dmesg say when you plug a usb device in? |

I just went back and reconfigured my kernel...there were a few usb options compiled statically that i made modules. The gave me a bit different results but still no working devices.
dmesg reports on the usb modules being loaded at boottime. Pluggin in or unplugging a device does not produce a message...
| Code: |
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub

lsmod output:

/proc/bus/usb/drivers has changed a little:
| Code: |
cat /proc/bus/usb/drivers
usbdevfs

Your lsmod output suggests that following your kernel reconfiguration you only have usb-core loaded. You'll need to put entries in /etc/modules.autoload for those things you made into modules.....
If that has no effect then normal troubleshooting applies - try just connecting 1 usb device at a time (without a hub etc.) and load only the necessary modules manually. Eventually you ought to find the device/module that is causing the problems. I hope that it doesn't turn out to be your usb interface... |

i loaded the modules by hand and plugged in the devices one by one ... it still did not register the devices. i'm starting to fear a hardware failure too...that would in part explain the erratic behavior of my usb drive when it worked...
Now that i think of it, i beleive there is a verbose debugging option in the kernel for the usb modules. I'll try to enable that and see if it tells me anything. Otherwise I guess i'll image my drive and use the XP restore disk just to make sure its a hardware problem  I have a feeling toshiba will either put windows back on the machine or refuse to fix it if i send it in with linux anyway... |

I'm not sure, maybe you also need the kernel hotplug option for that? Did you have it compiled with that? Can you upload your kernel .config somewhere and post the link here? Or just post the whole config file here... Or maybe just the usb / hotplug related stuff. Which kernel are you using?
Do you use the hotplug script?
| Code: | emerge hotplug
rc-update add hotplug default |

The hotplug scripts did it. Thats strange, I never had to use them before...
Oh well, not it works, and at least it wasn't a hardware failure  |
