linux driver 's probe doubts

Do not know if anyone encountered such a situation , drivers compiled under linux make menuconfig Select the appropriate device support , such as USB support, while the actual hardware may not have this equipment, kenerl startup will hang , attach the following information related to print :
[] ohci_init +0 x60/0x358
[] ohci_octeon_start +0 x24/0x90
[] usb_add_hcd +0 x32c/0x640
[] ohci_octeon_drv_probe +0 x1b0/0x2e0
[] driver_probe_device +0 xc8/0x240
[] __ driver_attach +0 xc0/0xc8
[] bus_for_each_dev +0 x6c/0xa8
[] bus_add_driver +0 x1d8/0x2c0

Disabling lock debugging due to kernel taint
Kernel panic - not syncing: Attempted to kill init!
If you remove the USB device config will not appear on the situation, we do not understand is that since there is no such device driver why can probe into and to initialize , or that there is no point to find the root of the problem ( which perform step will be , is the code written in question ? ) , which prawn can be urged Logically, even if the underlying hardware is not , the program should not hang up is not ?

------ Solution ------------------------------------ --------
feeling is that the USB hardware driver initialization failed. Not without hardware.
------ Solution ---------------------------------------- ----
when the platform driver and platform device for . name matches , probe to be executed, regardless of whether there is a hardware device .
------ Solution ---------------------------------------- ----
hang certainly code robustness problems you this is the beginning of the device the wrong time , you should present equipment ohci_init. Without this usb how work ah.
------ Solution ---------------------------------------- ----

+1 kernel does not have any hardware of their own judgment .
------ Solution ---------------------------------------- ----
just make menuconfig to add support but not in the driver code to reflect this change , so hung up. Landlord is doing kernel porting it ?

their top

problem Description more chaos , only there is a hardware USB device will be called to the driver's probe function , it is impossible
------ For reference only ---------------------- -----------------
I put the card to remove boot linux development board time will hang , it is not clear how the matter

Thank you upstairs Ge Jige answers , clear , thank
