I used to have udev-124-r1 and, every time I inserted a pendrive (formatted with FAT32) in my USB port, it used to appear in the thunar-0.9.3 removable devices list. Since I upgraded to udev-133, thunar doesn't respond any more to the insertion of the pen drive. dmesg shows that the drive is recognized correctly and mapped as /dev/sdb, and manual mounting works fine. #dmesg [...] usb 2-5: new high speed USB device using ehci_hcd and address 5 usb 2-5: configuration #1 chosen from 1 choice scsi6 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 5 usb-storage: waiting for device to settle before scanning usb-storage: device scan complete scsi 6:0:0:0: Direct-Access CREATIVE NOMAD MuVo TX 1223 PQ: 0 ANSI: 4 sd 6:0:0:0: [sdb] 241984 2048-byte hardware sectors (496 MB) sd 6:0:0:0: [sdb] Write Protect is off sd 6:0:0:0: [sdb] Mode Sense: 38 00 00 00 sd 6:0:0:0: [sdb] Assuming drive cache: write through sd 6:0:0:0: [sdb] 241984 2048-byte hardware sectors (496 MB) sd 6:0:0:0: [sdb] Write Protect is off sd 6:0:0:0: [sdb] Mode Sense: 38 00 00 00 sd 6:0:0:0: [sdb] Assuming drive cache: write through sdb: sdb1 sd 6:0:0:0: [sdb] Attached SCSI removable disk sd 6:0:0:0: Attached scsi generic sg2 type 0 I've already tried udev-135-r4, as well as recompiling thunar and rebooting my system. nautilus won't work either (but I don't know if it worked before, as I use it really seldom). I've no idea on how to obtain a verbose output from thunar (If someone tells me I'll be glad to investigate further). $ emerge --info Portage 2.1.6.7 (default/linux/amd64/2008.0/desktop, gcc-4.1.2, glibc-2.8_p20080602-r1, 2.6.27-gentoo-r2 x86_64) ================================================================= System uname: Linux-2.6.27-gentoo-r2-x86_64-Intel-R-_Core-TM-2_Duo_CPU_T7300_@_2.00GHz-with-glibc2.2.5 Timestamp of tree: Mon, 23 Feb 2009 01:45:01 +0000 app-shells/bash: 3.2_p39 dev-java/java-config: 1.3.7-r1, 2.1.6-r1 dev-lang/python: 2.5.2-r7 dev-util/cmake: 2.4.8 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.4.3-r1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.4_p6, 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=nocona -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-march=nocona -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch userpriv usersandbox" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="it_IT.UTF8" LC_ALL="it_IT.UTF8" LDFLAGS="-Wl,-O1" LINGUAS="it" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="X aac acl acpi alsa amd64 berkdb bluetooth branding bzip2 cairo cddb cdparanoia cdr cjk cli cracklib crypt cups curl dbus dga dri dts dv dvb dvd dvdr dvdread eds emboss encode esd evo exif fam ffmpeg firefox flac fontconfig fortran ftp gdbm gif gimp gpm gstreamer gtk hal iconv ipv6 isdnlog java jpeg kerberos ldap libnotify lzo mad midi mikmod mmx mp3 mpeg mtp mudflap multilib musepack mysql ncurses nls nptl nptlonly ogg openal opengl openmp pam pcre pdf perl php png ppds pppd python qt3support quicktime raw readline reflection samba sdl session smp speex spell spl sqlite sse sse2 ssl ssse3 startup-notification svg sysfs tcl tcpd threads tiff tk truetype unicode usb vorbis x264 xcb xml xorg xulrunner xv xvid zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev synaptics wacom" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="it" USERLAND="GNU" VIDEO_CARDS="intel" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
The actual problem is that the udev upgrade broke binary compatibility with HAL. Running revdep-rebuild fixed the problem.
