Usb-keyboard probelm..

[Rameshchandra]

Hi all,

My usb-keyboard is not detected in my ARM board(it is not even sensing
that a device has been inserted)...
So,i tried the following things...

1. I compiled and tried to insert the module usb-ohci.o 
It gave the following error while inserting...

usb-ohci.o: unresolved symbol pci_pool_free
usb-ohci.o: unresolved symbol pci_pool_alloc
usb-ohci.o: unresolved symbol pci_pool_destroy
usb-ohci.o: unresolved symbol pci_pool_create


2. I don't find where the above functions are 
defined in the drivers/usb directry of kernel 
source...

3. Then, with out any solutions...I tried to compile my kernel with
usb-ohci module itself insted of inserting it after... then again while
compiling the kernel source i got the following errors...
