No usb port on the docking station after docking

   Hi,


I have IBM ThinkPad A21m notebook and ThinkPad Dock. 

Docking working, but I have this problem:

I run ThinkPad battery powered without dock.
I connect ThinkPad to AC powered dock. I get ACPI debug message about
docking.
I enable slot:  echo 1 > /sys/bus/pci/slots/1/power - this working.

But no change on usb ports at the dock (lsusb - no info).


 Howto debug this ? There are no USB debug messages about changes - kernel
 compiled with USB debugging.

 Is problem 
 
 - ACPI related 
 - Any magick on the TI docking bridge
 - USB related problem

 ?

Howto debug this ?

USB port working without problem, if ThinkPad connected to docking station.

Sorry for my bad english.

  Many thanks
