this might be same problem as in #23313, but since i did not get any info from the reporter, i'm gonna open new bugreport. i have two usb devices connected to my box, but the system does not see them. support for usb is compiled into the kernel, modules for usb printer and usb scanner are loaded fine at boottime (or it seems this way): # dmesg usb.c: registered new driver usblp printer.c: v0.11: USB Printer Device Class driver usb.c: registered new driver usbscanner scanner.c: 0.4.12:USB Scanner Driver devices show up in /proc/bus/usb/devices, but they are not appearing under /dev/usb tree. also lsmod gives unusual output: scanner 10488 0 (unused) printer 7744 0 (unused) i had the same problem as in #23313 (lots of "modprobe: Can't locate module /dev/usb..." messages), but i don't use portmap. also, after upgrading gentoo sources to 2.4.20-r6 the messages disappeared, unfortunately with usb devices in /dev. i suspect this has something to do with module-init-tools, because it happened after i installed 2.6.0beta, though it could be also devfs related. the printer used to work before. # emerge info Portage 2.0.48-r7 (default-x86-1.4, gcc-3.2.3, glibc-2.3.2-r1) ================================================================= System uname: 2.4.20-gentoo-r6 i686 Pentium III (Coppermine) GENTOO_MIRRORS="ftp://ftp.tu-clausthal.de/pub/linux/gentoo/" CONFIG_PROTECT="/etc /var/qmail/control /usr/kde/2/share/config /usr/kde/3/share/config /usr/X11R6/lib/X11/xkb /usr/kde/3.1/share/config /usr/share/config" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" PORTDIR="/usr/portage" DISTDIR="/usr/portage/distfiles" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR_OVERLAY="/usr/local/portage" USE="x86 oss 3dnow apm avi crypt encode foomaticdb gif jpeg libg++ libwww mad mikmod mmx mpeg ncurses nls pdflib png quicktime spell truetype xml2 xmms xv zlib gdbm berkdb slang readline svga java guile sdl gpm tcpd pam ssl perl python esd imlib oggvorbis gtk motif opengl mozilla scanner X gtk2 gnome alsa cups dvd usb moznomail moznocompose moznoirc -arts -qt -kde" COMPILER="gcc3" CHOST="i686-pc-linux-gnu" CFLAGS="-mcpu=pentium3 -march=pentium3 -O3 -pipe" CXXFLAGS="-mcpu=pentium3 -march=pentium3 -O3 -pipe" ACCEPT_KEYWORDS="x86 ~x86" MAKEOPTS="-j2" AUTOCLEAN="yes" SYNC="rsync://rsync.gentoo.org/gentoo-portage" FEATURES="sandbox ccache buildpkg"
i did unmerge module-init-tools and remerge modutils as someone suggested, but it did not fix the problem.
CONFIG_USB_UHCI_ALT=y Try to enable it or CONFIG_USB_EHCI_HCD CONFIG_USB_OHCI In the kernel
support for usb is already compiled in and used to work (uhci) - somehow it broke after installing development-sources and module-init-tools. dmesg shows usblp and usbscanner, but these are 2.5.x drivers and running kernel is a stable one (2.4.20-r6). as stated before, removing module-init-tools did not help :(
A) Please try the latest baselayout [1.8.6.9] B) Try a vanilla kernel C) Remerge any kernel sources and run "make mrproper" in your kernel tree [ You'll need to reconfigure your kernel though ]
A. i've tried baselayout 1.8.6.9 and (masked) 1.8.6.10, no results B/C. neither vanilla sources nor make mrproper helps - i still get messages about development series kernel drivers being installed (usblp and usbscanner), though i've unmerged development sources along with module-init-tools. what's more interesting, devices seems to be recognized by the kernel properly: $ /usr/sbin/lsusb Bus 002 Device 001: ID 0000:0000 Bus 002 Device 002: ID 058f:9254 Alcor Micro Corp. Hub Bus 001 Device 001: ID 0000:0000 Bus 001 Device 002: ID 07b3:0413 Plustek, Inc. $ uname -a Linux tool 2.4.22 #1 czw wrz 4 22:48:32 CEST 2003 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux yet still: $ cat /proc/bus/usb/drivers usbdevfs hub 0- 15: usblp 48- 63: usbscanner
more info in this: i have just installed fresh new gentoo and it's acting the same way - there are no usb devices in /dev. also looks like usblp and usbscanner are valid drivers for 2.4 kernel. i used latest stable gentoo-sources 2.4.20-r7 and dmesg gives the same output as above. i've also tried compiling printer and scanner support into the kernel and in the modules - both failed. i was wondering if it could be some interrupr conflict, as two usb devices are pluuged-in? i'll keep digging :)
ok, you may close this one. most probably this is not gentoo specific bug, but as suspected - interrupt conflict. i'll do some more testing and send a report to kernel people.
need upstream fix
