Why do you add a netmd_receive_track function stub to session.c? We already have a corecctly working track receiption code in secure.c Are you sure that it is working correctly? This is the main code for the bulk transfer in netmd_secure_real_recv_track(...) : . . . read = libusb_bulk_transfer((libusb_device_handle*)dev, 0x81, data, (int)chunksize, &transferred, 10000); if (read >= 0) { done += (uint32_t)read; fwrite(data, (uint32_t)read, 1, file); . . . read is the return code from libusb_bulk_transfer. So if return code is 0 which means no error,data size of 0 will be written to the file and 0 will be added to the "done" variable. We have to use the variable "transferred" to check the data size. So the code must look like this: read = libusb_bulk_transfer((libusb_device_handle*)dev, 0x81, data, (int)chunksize, &transferred, 10000); if (read >= 0) { done += (uint32_t)transferred; fwrite(data, (uint32_t)transferred, 1, file); This works, please change this. I do not make a patch because i am working on other changes and do not want to rebase yet. Thomas |
