Comment 11 for bug 392144

Hi,

I have a 'funky' issue with USB on my Dell Latitude D620 too. I'm on a docking station, a USB cable going from that to a Dell 1905 LCD, and that going to a USB Microsoft Ergo keyboard and mouse. At boot the mouse will not work, and the keyboard has been 'iffy' - Then most of the time if I unplug and replug them into the monitor USB hub, they will both work fine. Just now I tried unplugging my mouse from the monitor, plugged in on the doc, and it worked, then plugged in direct to the laptop ports, and it worked... Only to find my usb keyboard stopped working... Unplugged keyboard and mouse - put them on the laptop, now neither works. :(

dmsg snip from boot time, and then for this event. Not sure what other bits to grab since I haven't really had usb issues before, so I'll just attach some 'normal' bits.. Darn - or I would attach if I could start a terminal. Since the usb lock, terminal will no longer launch, etc. weird. I'll see if I can get /var/log bits after a restart.
