Hi, I'm trying to integrate libusb, with Cypress FX2, with libev (event loop) by using the "polling and timing" function:
http://libusb.sourceforge.net/api-1.0/group__poll.html So by calling the libusb_get_pollfds It return 3 file descriptor. So my question is why 3? 2 files descriptor (POLLIN) that could be read. 1 file descriptor (POLLOUT) that could be write. So normally in the sync API the endpoint6 (0x08) was used for writing, with libusb_bulk_transfer() and endpoint (0x88) was used to read data. So I can see that POLLOUT could be the endpoint8 and 1 of the POLLIN the endpoint6? If this is correct what is the other POLLIN file descriptor? How could I distinguish them? Still searching in the Documentation/Code but this is not clear to me, yet.
