 Posted: Sat Nov 27, 2004 10:55 pm Post subject: USB problems after upgrade |
 |
|
Hi,
yesterday I upgraded my "world"  and it seems that something bad happend to USB. I suspect either hotplug or something around dev problems. The symptoms are very simple - my USB mouse is no longer detected by system. The only lines in dmesg that say about USB are:
usbcore: registered new driver usbfs
usbcore: registered new driver hub
what I'm sure is that:
- hotplug has been upgraded
- I compiled new kernel, 2.6.9-r6, but now I boot from the old
2.8.8-r3 again and the symptoms are the same.
I'm not very good in this part of linux, so I didn't attach more debug information as I'm not sure what to take a look at. Maybe you could suggest what files / command output could help you to diagnose the problem?

I'm a beginner, so take this with "a grain of salt". I suspect
that you have run into the "hotplug/coldplug" issue. If you
search for the words
| Quote: |
hotplug hot-plug coldplug |
you will find a bunch of recent threads on the Gentoo forums that
will likely give an answer.
BTWay, in your new kernel, are you using `udev' or the older
`devfs'? In `make menuconfig' did you

I use udev, but maybe upgrade made switched environment to devfs - is this possible? All other devices (at least basic ones) seem to behave properly.
I don't think it's just a compile options to the kernel as my USB doesn't work also with my old kernel which was not recompiled during/after upgrade and it was working with it. Maybe it's something with modules loading?

| I don't have a suggestion, but I'm having a problem that is most likely connected with yours. I'm having huge problems with my USB drive that has worked perfectly for ~1.5 years, then after a fairly recent update, it doesn't work on any of my computers. If you figure out your problem, please let me know... |

Got it! 
I noticed that apart from usbcore no usb-related devices were loaded during system startup. So I edited /etc/modules.autoload.d/kernel-2.6 and added the following three lines:
| Code: | uhci-hcd
ohci-hcd
ehci-hcd
|
and now dmesg contains:
usbcore: registered new driver usbfs
usbcore: registered new driver hub
USB Universal Host Controller Interface driver v2.2
ACPI: PCI interrupt 0000:00:0b.0[A] -> GSI 10 (level, low) -> IRQ 10

usbcore: registered new driver usbhid

I'm not sure if this is an elegant solution, but it does work !
