The code part lookslike this:
printf("Resetting USB...\n");
ret = libusb_reset_device(_rt_dif.dev_handle);
if (ret < 0 && ret != LIBUSB_ERROR_NOT_FOUND)
fprintf(stderr, "error resetting
"
"after detach\n");
fprintf(stderr, "doing
libusb_set_configuration(dif->dev_handle, 1)\n");
libusb_set_configuration(dif->dev_handle,
1);
sleep(2);
fprintf(stderr, "dif->dev_handle %08x\n", dif->dev_handle);
for reset it uses _rt_dif.dev_handle, and you made me add an operation
with dif->dev_handle, is this correct?
anyway:
Resetting USB...
doing libusb_set_configuration(dif->dev_handle, 1)
dif->dev_handle 28449f00
Opening USB Device...
No such Alternate Setting: "rootfs"
Thanks
