Hi,
My app needs be able to read & write (to different enpoint) at same time,
and my code is not working. but if I change the call to Synchronous
, everything works fine, could any one tell me what I did wrong here?
thx
CallBackData* userdata=new CallBackData();
userdata->ExitTransfer=false;
int err =0;
libusb_transfer* transfer =libusb_alloc_transfer(0);
if (!transfer)
{
err=-ENOMEM;
return NULL;
}
libusb_fill_bulk_transfer
(transfer,m_handle,endpoint,reinterpret_cast<unsigned char*>
(pbBuffer),
c_uiLength,LibUSBDevice::WriteCallback,userdata,ITP_TRANSFER_TIMEOUT);
if (!err)
{
err = libusb_claim_interface(this->m_handle, 0);
err=libusb_submit_transfer(transfer);
while (!userdata->ExitTransfer)
{
//I also added Lock here for the whole block here and
to serialize the call to
//libusb_handle_events_timeout_completed, but it still does not work.
struct timeval tv = { 1, 0 };
int completed =0;
err = libusb_handle_events_timeout_completed(NULL, &tv,&completed );
}
}
...
