| melodie | hi | 21:46 |
|---|---|---|
| melodie | can someone help me to help someone who has trouble with USB 3 and usb_xhci_platform on a Trusty Ubuntu official install (appearantly up to date) ? | 21:47 |
| melodie | I also have a vm with a Trusty 14.04.2 install runnning and have done a research on the XHCI drivers in the config of the kernel and in the system and seeing the results I thought I'd come here for more insights. | 21:47 |
| melodie | funny, the kernel has USB_XHCI_PLATFORM enabled as "module" in the config-`uname -r` kernel, but not available in the /lib/modules/* directory | 22:16 |
| melodie | the default stock kernel | 22:17 |
| melodie | I can provide the thread on the forum, if someone here reads French | 22:17 |
| apw | melodie, what module name are you looking for for that config item, on vivid at least i have xhci-plat-hcd.ko | 22:19 |
| melodie | apw I have seen it in vivid too | 22:20 |
| melodie | I am testing in vbox trusty installing vivid-lts kernel packages | 22:20 |
| melodie | I will reboot the vm very soon | 22:20 |
| apw | but do you have that module name in /lib/module, as that is the module that is made by that config item | 22:21 |
| melodie | it is not me who has usb 3 trouble, it's a buddy on a forum | 22:21 |
| melodie | in trusty /lib/module does not have ANY xhci module | 22:21 |
| melodie | whatsoever | 22:21 |
| melodie | of any kind | 22:21 |
| apw | what packages do they have installed | 22:22 |
| apw | for the kernel, linux-image ? linux-image-extra? | 22:22 |
| melodie | http://forum.malekal.com/probleme-reconnaissance-cle-usb-32go-t51085.html | 22:22 |
| melodie | yes I got him to install linux-image-extra-virtual | 22:22 |
| melodie | he has 3.13.0-52-generic x86_64 | 22:24 |
| melodie | he said in Ubuntu 14.04 32 bits not problem and in Ubuntu 14.04 64bits he can't have USB3 32 GB stick work in the USB3 hub | 22:24 |
| melodie | but he can use it in usb2 hub | 22:24 |
| melodie | I think perhaps he did have linux-image-extra in 32bits, but not sure really. | 22:25 |
| melodie | he met with other issues meanwhile which we try to fix | 22:25 |
| apw | -rw-r--r-- root/root 11204 2015-05-20 11:41 ./lib/modules/3.19.0-18-generic/kernel/drivers/usb/host/xhci-plat-hcd.ko | 22:26 |
| apw | the module is in th linux-lts-vivid -extras package | 22:27 |
| apw | on 64bit packages | 22:27 |
| melodie | yes same here in Vivid, but in Trusty with some kernels 3.13.0-52-generic x86_64 and other 3.13.0* previously installed, none | 22:27 |
| melodie | apw so is that only in 64bits packages that it happens and in 32bits packages the stock kernel would provide the xhci modules? | 22:28 |
| melodie | (so I would understand the situation clearly) | 22:28 |
| apw | no they would be in the same split | 22:28 |
| melodie | but there is none at all | 22:28 |
| melodie | no xhci in Trusty with the default kernel | 22:29 |
| melodie | if they are compiled with the "y" option in the config-* file, it should still appear under /lib/modules/* but no *xhci* at all appears | 22:30 |
| apw | no it seems there is a special for that option on trusty | 22:32 |
| melodie | also: are we sure that xhci-plat-hcd.ko stands for USB_XHCI_PLATFORM ? | 22:32 |
| apw | ifneq ($(CONFIG_USB_XHCI_PLATFORM), ) | 22:32 |
| apw | xhci-hcd-y += xhci-plat.o | 22:32 |
| apw | endif | 22:32 |
| apw | so it is part of xhci-hcd and builtin | 22:33 |
| melodie | which means what exactly? (in current words?) | 22:33 |
| apw | even if =m | 22:33 |
| melodie | =m but so far modprobe on the name returns "no such file" | 22:33 |
| melodie | I felt concerned about this issue because Trusty is a LTS, and because nowadays USB3 comes more and more used by the people | 22:34 |
| apw | right, its a frig, =m does not make a module there | 22:34 |
| melodie | excuse me, English is not my native language. What does the word "frig" mean? | 22:35 |
| apw | bodge | 22:35 |
| melodie | a bug? | 22:35 |
| apw | not normal behavior | 22:35 |
| melodie | ok | 22:35 |
| melodie | so did we lift a bug here? | 22:35 |
| apw | not bug, just unexpected meaning of the option i think | 22:36 |
| melodie | do you have the possibility to talk about that to some people in charge with the kernels in Ubuntu Trusty LTS? | 22:36 |
| apw | i am saying that it is built, and builtin i believe even though =m | 22:38 |
| melodie | how is that possible? I have built some of my kernels in the paste times, and "y" is builtin and "m" needs to be loaded at boot | 22:38 |
| apw | yes that is what it means normally | 22:39 |
| apw | and in vivid, it does | 22:39 |
| melodie | and when checking with command lines, to have it loaded we can check either by a grep on the chain in the config file or by a find in the /lib/modules directory. Else, the module isn't available : which explains that this guy keeps hitting his bottom on the floor: the usb3 sticks (32gb) are detected only when plugged in a USB2 hub or direct connector. No USB3 hub or direct connector could see it so far (dmidecode, lshw and lspci checked) | 22:41 |
| apw | obj-$(CONFIG_USB_XHCI_PLATFORM) += xhci-plat-hcd.o | 22:41 |
| melodie | something must have gone wrong on the way | 22:41 |
| apw | is vivid, so it has normal behavior | 22:42 |
| melodie | I'll advice him to try with the vivid kernels | 22:42 |
| apw | but trusty has different code | 22:42 |
| apw | yep, do | 22:42 |
| melodie | kernel kernel headers and linux-image-extra from vivid | 22:42 |
| melodie | anyway it might be interesting to let the people in charge know about that, they might want to have a look into it | 22:43 |
| melodie | ? | 22:43 |
| apw | file a bug about it, it might be related to | 22:45 |
| apw | obj-$(CONFIG_USB_XHCI_HCD) += xhci-hcd.o | 22:45 |
| apw | if that is =m as well | 22:45 |
| melodie | I can't file a but about it, I would need to have a similar usb3 32gb stick as this guy has which I don't have. | 22:50 |
| melodie | if I file a bug I need to be able to test what needs to be tested | 22:50 |
| melodie | or it serves no purpose | 22:50 |
| melodie | this is why the persons in charge of those kernels should be called in so they can check. | 22:51 |
| melodie | if supposedly they do have usb sticks needing xhci_* modules | 22:52 |
| melodie | apw thanks for your help | 23:04 |
