USB Serial device disconnect causes IRQ disable

Hi
I don't have any driver modules. I have everything built into kernel.
When can this kind of IRQ disable happen, what causes this. The issue happened because of hotplugging my device but the device works fine.
usb_register(driver) might have caused the issue. How do we debug this problem.
Thanks
Amruth p.v
