Using "usb_interrupt_read" usb.h



  • Hello,

    I've an application that comunicates with a PIC32 uC. I already have it running, but now i want to change the Qt application to trigger an interrupt when the PC receives USB data.

    I'm using usb.h i think from libsub driver under linux 64 bit, the function i used since now to read is:

    @int usb_bulk_read(usb_dev_handle *dev, int ep, short int *bytes, int size, int timeout);@

    ...but in the same library there's another function for interrupt readings:

    @int usb_interrupt_read(usb_dev_handle *dev, int ep, char *bytes, int size, int timeout);@

    I tried to use it but without success...Mi idea is to read the data only when the computer receives it, instead by polling.

    Any idea or suggestion?

    Thanks
