Hi Pratyush,
I need to test the tarnsfer on interrupt end point also.As such there
are no test cases for interrupt end point tranfers ,also there is no
support in gadget zero for interrupt end points.
Can you give me any inputs on testing interrupt end point transfers.
Sorry, I have not worked with interrupt endpoint.
So, if you need to test it using zero gadget, then you will have to add
it's support in zero gadget as well as in usbtest.c.
May be you can add it's support
You can see following patch of Paul for reference (how to add new endpoints)

usb: gadget: add isochronous support to gadget zero
However, interrupt should be quite easier than isoc. It should be very
much similar to bulk, only difference should be that you need to add a
bInterval field and modify type as interrupt in endpoint descriptor.
So, for a quick test just modify these two fields in f_sourcesink and
pass force_interrupt = 1 to usbtest.ko. Use test case for bulk as that
for interrupt and it should work. You might need to modify usbtest_info
struct too.
