[linux-usb-devel] Re: USB: gphoto2 hangs, device disconnection oddity (was Re: 2.6.5-rc1-mm2)

[Ari Pollak]

Attached is the output of alt-sysrq-t. I noticed that there is no 
mention of khubd in the trace output while the mouse is connected, but 
it does show up in the output before I connect a mouse. Also, removing 
usbmouse and hid modules while the USB mouse is connected does succeed.

Here's something you could do.  Just testing the mouse problem, not any of 
the other more complicated things.  When you unplug the mouse and start 
getting those suspend_hc/wakeup_hc messages, capture a task status dump 
(Alt-SysRq-t).  That might be of use.

Another thing to try.  Before unplugging the mouse, try to rmmod either or 
both of its drivers: usbmouse or hiddev.
