Shared Irq with uhci_hcd

Jump to solution

Hi all,

 

 

I have written driver, usiing eUSB and while flashing the board, i got issue as 

"

kernel: irq 18: nobody cared (try booting with the "irqpoll" option

When I go through this issue, I came to know uhci_hcd_irq is sharing set of irqs and one of the irq handler is handling properely.

But this code regards to drivers/usb/core/hcd.c , this is core file part of USB 

Should I really change the code from this area?

 

Please help me out is there any solution to resolve the issue instead of changing the core file.

or  we can change core file also, if it really getting stuck

 

Thanks & Regards

Satish.G

Hi 

I resloved the issue ,

This is because USB is connected through PCI and PCI is not supporting to initialise the USB device , USB core is excepting IRQ response from PCI Device, but PCI is not responding.

Reason is PCI is not supporting the specific IRQ pin as PCI card is pretty old.

 

Thanks & Regards,
