Bug#622649: linux-image-2.6.38-2-amd64: unable to enumerate USB device on port 6
Dear maintainers, this bug is also and still in 2.6.39-rc7-amd64 from debian/experimental. Jonathan's patch did not work. Maybe we should revert to the ohci-hcd module from the last working kernel? I checked some livefile systems, with newer kernels - they got the same result (for example BackTrack5). I suggest, to merge this bugreport and #620848. With this bug, these kernels are still not usable for me (and I suppose, there might be other people with the same problem, too) Please don't feel annoied by me, I just wanted to mention, there is IMO a big problem. Thank you for your considerateness. Best regards Hans -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Bug#622649: linux-image-2.6.38-2-amd64: unable to enumerate USB device on port 6
Hi Jonathan, thank you for building the kernel with the patch. I just tested it, but sadly I got the same problem again. So I think, Alan's patch does not generate the wished result. To make sure, to get rid of old modules, i completely deinstalled all 2.6.38- packages (image and header-files), but had no success. Sorry for that! The bug is still existent. However, your work helped me a lot, to test it fast. Thanks! Hans -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Am Freitag, 15. April 2011 schrieb Hans-J. Ullrich: I'll handle this, Alan. Ben. Thank you very much, Ben! Hans Hi Ben, Alan and Jonathan, I was not lazy and again tried to rebuild the module(s) with the patched source-code, but did not succeed. I downloaded the kernel-sources, unpacked them to /usr/src and then linked the sources to /usr/src/linux. Copying /boot/config-2.6.38-2-amd64 to /usr/src/inux/.config. Then started make menuconfig and added in version option -2-amd64, to make sure I have the same version than the running kernel. After this I started make modules below /usr/src/linux, to build just the modules. After building them, I copied ohci-hcd.ko and ehci-hcd.ko to /lib/modules/2.6.38-2-amd64/drivers/usb/host and overwrote the existing *- hcd.ko modules. With depmod -a I finished. But I can still not load those kernel modules. I also remarked, the new ones are much bigger (old ones are about 60kB, the new ones about 700kB). I also tried make-kpkg --append-to-version=-2-amd64 modules_image but the process stops at the point, where it wants to clean up ( /usr/bin/make clean is the last line I see). What did I do wrong? In the past, I already build some kernels, but the last one was a long time ago (I think, it was 2.6.20 something) and did it by using make-kpkg. However, when the patched kernel-package is uploaded, Or if you will send me a download-link to a package, I will be very pleased to test it! Thank you very much for your help.

Bug#622649: linux-image-2.6.38-2-amd64: unable to enumerate USB device on port 6
(-cc: various people) Hi, Hans-J. Ullrich wrote: Then started make menuconfig and added in version option -2-amd64, to make sure I have the same version than the running kernel. Debian kernels have CONFIG_MODVERSIONS=y set: Usually, you have to use modules compiled with your kernel. Saying Y here makes it sometimes possible to use modules compiled for different kernels, by adding enough information to the modules to (hopefully) spot any changes which would make them incompatible with the kernel you are running. After this I started make modules below /usr/src/linux, to build just the modules. After building them, I copied ohci-hcd.ko and ehci-hcd.ko to /lib/modules/2.6.38-2-amd64/drivers/usb/host and overwrote the existing *- hcd.ko modules. With depmod -a I finished. These gymnastics should not be necessary. Did insmod filename work? If not, what output did it write? (Invalid module format, I guess?) It is possible the kernel version you are building has a different ABI than the version you are running. It tends to be easiest to test entire kernels still. Did you try make deb-pkg? What did I do wrong? In the past, I already build some kernels, but the last one was a long time ago (I think, it was 2.6.20 something) and did it by using make-kpkg. I haven't kept up with the latest make-kpkg developments. The upstream makefile rules to build a Debian package are much simpler and have worked reliably for me for what it's worth.

Hi Jonathan, Debian kernels have CONFIG_MODVERSIONS=y set: yes, this is set! entire kernels still. Did you try make deb-pkg? No, I dis not. I tried modprobe ohci-hcd, but got no output. Well, for now, I gave up. As Ben wanted to handle the patch, I suppose, there will be a new kernel-version during the next days. Then I will test it and this way, other people can test it, too. In the German-user-list people wrote of the same problem and so there are more testers than only me. I will report as soon as possible.

Hello Alan,
it lasted a little bit, as I am not very experienced with patching of source-
code. However, I did as you suggested, and hope I did everything correct.
I compiled the source again and it worked. Please take e look at the source
code. I send it below.
If I did it correct, I suggest, to patch all versions of the linux kernel
since version 2.6.32-5-amd64-30 and higher.
Maybe a new and patched kernel version should be uploaded to the repository as
soon as possible, what do you think?
Thank you very much for your help!!!
Cheers
Hans

Hi Alan, I was happy too early, sorry for that. It seems, the compiled module can not be loaded somehow. Maybe it is my fault and I made a mistake at editing or compiling. As I told, I am not experienced with patches of source code. However, I will be pleased, if I can help with testing. If there is a kernel- package available, I will be pleased, to install it and send the results. Sorry for my prior message, which I sent too early!
