Issues with usb devices: 0425:f102 Motorola Semiconductors HK, Ltd G-Tech U+P Wireless Mouse -does not work. An added logitech usb wireless mouse worked though. 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter -stops working after awhile, and after pm-suspend. Falling back linux, udev, mkinitcpio, nvidia makes devices work again. Xorg.0.log-no errors- says mouse was added: (**) Option "config_info" "udev:/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.1/1-4.1.1/1-4.1.1:1.0/input/input8/event8 (II) XINPUT: Adding extended input device "G-Tech CHINA U+P Wireless Mouse " (type: MOUSE, id 8) kernel.log snippet, maybe of use: May 21 21:06:40 localhost kernel: [ 139.034500] ------------[ cut here ]------------ May 21 21:06:40 localhost kernel: [ 139.034513] WARNING: at net/mac80211/driver-ops.h:10 ieee80211_do_stop+0x694/0x6b0 [mac80211]() May 21 21:06:40 localhost kernel: [ 139.034515] Hardware name: Dell DM051 May 21 21:06:40 localhost kernel: [ 139.034517] Modules linked in: fuse aes_x86_64 cryptd aes_generic autofs4 nfsd exportfs nfs nfs_acl lockd auth_rpcgss fscache sunrpc ext4 jbd2 mbcache crc16 arc4 uvcvideo videobuf2_vmalloc rt2800usb videobuf2_memops videobuf2_core rt2x00usb videodev rt2800lib rt2x00lib media usbhid crc_ccitt mac80211 snd_usb_audio cfg80211 snd_usbmidi_lib snd_rawmidi snd_seq_device hid rfkill usb_storage uas nvidia(PO) iTCO_wdt e100 iTCO_vendor_support snd_hda_codec_idt psmouse evdev snd_hda_intel acpi_cpufreq i2c_i801 mperf dcdbas intel_agp serio_raw snd_hda_codec mii i2c_core intel_gtt processor button snd_hwdep microcode snd_pcm_oss snd_mixer_oss snd_pcm snd_page_alloc snd_timer snd soundcore btrfs crc32c libcrc32c zlib_deflate sd_mod sr_mod cdrom pata_acpi ata_generic ata_piix uhci_hcd libata scsi_mod ehci_hcd usbcore usb_common May 21 21:06:40 localhost kernel: [ 139.034570] Pid: 1136, comm: kworker/u:65 Tainted: P W O 3.4.0-1-ARCH #1 May 21 21:06:40 localhost kernel: [ 139.034572] Call Trace: May 21 21:06:40 localhost kernel: [ 139.034576] [<ffffffff810515df>] warn_slowpath_common+0x7f/0xc0 May 21 21:06:40 localhost kernel: [ 139.034579] [<ffffffff8105163a>] warn_slowpath_null+0x1a/0x20 May 21 21:06:40 localhost kernel: [ 139.034590] [<ffffffffa11b0244>] ieee80211_do_stop+0x694/0x6b0 [mac80211] May 21 21:06:40 localhost kernel: [ 139.034595] [<ffffffff8138caa9>] ?
