Using bulk out you can separate the packed. 1.0 standards does not allow more then 8 at once.
Use bulk you can try this
Code: Select all
while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer + 0, 8);
while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer + 8, 8);
while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer + 16, 8);
etc...
