USB Interrupt Transfer.

NTDEV
1

Hi all,

I am developing a minidriver for USB Scanner. This scanner interrupts
when a push button is pressed on the scanner.

The problem is how will my minidriver can recognise this push buton
event? In the present implementation, we poll for the push button event
in minidriver. My target is to recignise the event without polling for
it.

One more question. Is there is any way by which I can register an ISR
(Interrupt Service Routine) or something similar to it with USB Kernel
driver (USBScan.sys) from my minidriver to recognise the interrupt
occurred?

Any pointers are hugely appreciated…

Thanks and Best Regards

Hi Srinidhi,

Can you make the push button cause an interrupt to be fired off , which your
driver could respond to ?

HI Srinidhi,
Do you use usbscan.sys to access the scanner?
my further question is based on your answer.

thanks
