Hello .
I just found out that with latest 2.6 test i have hard lock when i remove my Alcatel 
USB cable.
I managed to found a reason: when i remove cable - usb_disconnect function called which
call usb_disable_device at the same time usbdefvs try to free some internal data and 
call
usbdev_release , so what is happen inside usb_disable_device we put dev->actconfig=0
and at the same time we use dev->actconfig(assuming itis not NULL) in releaseintf. as 
a result we have oops inside
interrupt and PC is dead. Fix is to remove dev->actconfig=0 from  usb_disable_device.
For me after this patch everything is working properly.

p.s. Please CC to my email because i am not subscribed.
