In hidusbfx2 sample driver, they used Timerfunction
(Hidfx2EvtTimerfunction). i.e., they create a timer and queue the
IOCTL_HID_READ_REPORT request and then complete this request in timer
function. Here they didnt use isr. But I am using isr, and I want to
complete this request in dpc. If I do this, whether
IOCTL_HID_READ_REPORT is called by HIDCLASS driver when I didnt
receive interrupt? (i.e, If I didnt get interrupt, the
IOCTL_HID_READ_REPORT request is not completed, so next time this
ioctl is not called). Am right? or Any suggestions?

can you please restate your question? are you saying that you get the IOCTL
but your ISR does not get called? remember that your DPC for ISR can be
already queued when you get another ISR call. you must queue up enough
state in your extension/context to be able to process mutliple ISR calls
from one DPC callback
