So it probably not a bad port. Also, what looks like a power LED may be a "CPU is reset and running LED" I don't have schematics so I can't tell. I did plug in another 1.0 device which has a LED and it has power so maybe this is a "CPU is running LED" and it takes a reset to turn it on. Another possibility is that the device itself is not recovering from a suspend without a reset. Is there a tool for forcing the device in and out of the suspend state? I tried setting power/state 0/2 and that didn't seem to do anything. But if it is a problem in the device, why does it work in a hub and not on the root? Don't the hubs get suspended too? A third possibility, after the device resumes some kind of uevent isn't getting sent to the higher layers. How do I turn on udev logging at boot? Does udev work right if this happen? usb finds device 2 seconds are up device suspends drivers loads which triggers resume Trace of udev unplug/plug of the device UEVENT[1168458162.824169] remove@/class/sound/mixer UEVENT[1168458162.824241] remove@/class/sound/dsp UEVENT[1168458162.824255] remove@/class/sound/audio UEVENT[1168458162.824269] remove@/class/sound/pcmC0D0p UEVENT[1168458162.824282] remove@/class/sound/pcmC0D0c UEVENT[1168458162.824295] remove@/class/sound/controlC0 UEVENT[1168458162.824402] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.0 UEVENT[1168458162.824419] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.1 UEVENT[1168458162.824487] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.2 UEVENT[1168458162.824554] remove@/class/usb_endpoint/usbdev4.5_ep83 UEVENT[1168458162.824620] remove@/class/input/input6/event3 UEVENT[1168458162.824684] remove@/class/input/input6 UEVENT[1168458162.824701] remove@/class/usb/hiddev0 UEVENT[1168458162.824716] remove@/class/usb UEVENT[1168458162.824848] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.3 UEVENT[1168458162.824920] remove@/class/usb_device/usbdev4.5 UEVENT[1168458162.824986] remove@/class/usb_endpoint/usbdev4.5_ep00 UEVENT[1168458162.826492] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2 UDEV [1168458162.832415] remove@/class/sound/mixer UDEV [1168458162.832450] remove@/class/sound/dsp UDEV [1168458162.854569] remove@/class/sound/audio UDEV [1168458162.854750] remove@/class/sound/pcmC0D0c UDEV [1168458162.854852] remove@/class/sound/controlC0 UDEV [1168458162.854953] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.0 UDEV [1168458162.855049] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.1 UDEV [1168458162.855145] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.2 UDEV [1168458162.855247] remove@/class/usb/hiddev0 UDEV [1168458162.855340] remove@/class/usb UDEV [1168458162.855439] remove@/class/usb_device/usbdev4.5 UDEV [1168458162.855547] remove@/class/usb_endpoint/usbdev4.5_ep00 UDEV [1168458162.855642] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.3 UDEV [1168458162.855798] remove@/devices/pci0000:00/0000:00:1d.2/usb4/4-2 UDEV [1168458162.856778] remove@/class/usb_endpoint/usbdev4.5_ep83 UDEV [1168458162.871826] remove@/class/sound/pcmC0D0p UDEV [1168458162.910740] remove@/class/input/input6/event3 UDEV [1168458162.913831] remove@/class/input/input6 UEVENT[1168458170.575575] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2 UDEV [1168458170.575575] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2 UEVENT[1168458170.575766] add@/class/usb_endpoint/usbdev4.6_ep00 UDEV [1168458170.575766] add@/class/usb_endpoint/usbdev4.6_ep00 UEVENT[1168458170.575946] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.0 UDEV [1168458170.597907] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.0 UEVENT[1168458170.662426] add@/class/sound/pcmC0D0p UDEV [1168458170.662426] add@/class/sound/pcmC0D0p UEVENT[1168458170.662623] add@/class/sound/pcmC0D0c UDEV [1168458170.662623] add@/class/sound/pcmC0D0c UEVENT[1168458170.662755] add@/class/sound/dsp UDEV [1168458170.662755] add@/class/sound/dsp UEVENT[1168458170.662870] add@/class/sound/audio UDEV [1168458170.662870] add@/class/sound/audio UEVENT[1168458170.663006] add@/class/sound/controlC0 UDEV [1168458170.663006] add@/class/sound/mixer UEVENT[1168458170.663121] add@/class/sound/mixer UEVENT[1168458170.663191] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.1 UEVENT[1168458170.663261] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.2 UEVENT[1168458170.663327] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.3 UEVENT[1168458170.663405] add@/class/input/input7 UEVENT[1168458170.663465] add@/class/input/input7/event3 UEVENT[1168458170.663526] add@/class/usb/hiddev0 UEVENT[1168458170.663595] add@/class/usb_endpoint/usbdev4.6_ep83 UEVENT[1168458170.663662] add@/class/usb_device/usbdev4.6 UDEV [1168458170.707150] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.3 UDEV [1168458170.707263] add@/class/usb_endpoint/usbdev4.6_ep83 UDEV [1168458170.707324] add@/class/usb/hiddev0 UDEV [1168458170.812076] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.2 UDEV [1168458170.852179] add@/class/sound/controlC0 UDEV [1168458170.852316] add@/devices/pci0000:00/0000:00:1d.2/usb4/4-2/4-2:1.1 UDEV [1168458170.928057] add@/class/usb_device/usbdev4.6 UDEV [1168458171.003720] add@/class/input/input7 UDEV [1168458171.072158] add@/class/input/input7/event3 -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------------------------- Take Surveys.
