Hi, I am facing an issue with a request of USB bulk transfer from a linux host to DaVinci DM6467 EVM. I used USB_to_PCI_loop_test.c as a base and tried to modify for sending a bulk transfer write request. I get an error status from following snippet of code: bulk_transfer.ep = 2; bulk_transfer.len = sizeof(USB_TEST_DATA); bulk_transfer.timeout = 10; bulk_transfer.data = &USB_TEST_DATA; status = usbdev_ioctl (fd, dev->ifnum, USBDEVFS_BULK, &bulk_transfer); printf("Bulk status 0x%x\n",status); ----> I get 0xfffffff and DaVinci EVM does not get any data. Is there any example code for implementing USB bulk transfer from a linux host to DaVinci ? I have searched the web but could not find anything.This is a very simple thing to perform data transfer so my understanding is there must be something available to perform this. The test code uses test ioctl number which are not very useful when sending actual data. Thanks, Neeraj
