Re: libusb file descriptors

[terence12 <tez...@gm...>]

Ok. With interrupt transfers in particular there is an internal polling
mechanism which will receive an "in token" when data is about to be
transmitted. How is there not anything that triggers a flag when interrupt
data has been received?

Also, if I create a program for say a mouse which uses interrupt transfers,
where the mouse is mostly transmitting packets to the controller, does that
mean I have to continually call libusb_interrupt_transfer() on an in end
pointer? It doesn't seem practical and there doesn't seem to be a practical
solution for concurrent devices controlled from the same program.

Also is it safe to continually call libusb_interrupt_transfer() on an in end
pointer from one thread, and occassionally use libusb_interrupt_transfer()
to write to an out pointer for the same device?

Thanks,
Terence
