Hi Hiroyasu

Can you share exactly what issue your customer is facing with the new LightCrafter?

Thanks

Hi Hiroyasu,

Do you still need the answer to your query? If not we'll tentatively be closing this thread.

Thanks & Regards,
Hirak.

Dear Azad

Sorry for delay.
My customer can not connect between DLP4500 Light Crafter and PC via USB.
I asked them changing firmware. But It was not working.

After this, They change GUI of source code like this, it was working.
We look for this root course. Is it possible due to difference version ?

===============
●GUI\hidapi-master\windows\hid.c
HID_API_EXPORT hid_device * HID_API_CALL hid_open(unsigned short vendor_id, unsigned short product_id, const wchar_t *serial_number) {
/* TODO: Merge this functions with the Linux version. This function should be platform independent. */
struct hid_device_info *devs, *cur_dev;
const char *path_to_open = NULL;
hid_device *handle = NULL;

devs = hid_enumerate(vendor_id, product_id);
cur_dev = devs;
while (cur_dev) {
if (cur_dev->vendor_id == vendor_id &&
cur_dev->product_id == product_id) {
if (serial_number) {
if (wcscmp(serial_number, cur_dev->serial_number) == 0) {
path_to_open = cur_dev->path;
break;
}
}
else {
handle = hid_open_path(cur_dev->path); //20181002Add
if (handle) { //20181002Add
break; //20181002Add
} //20181002Add
// path_to_open = cur_dev->path; //20181002Delete
// break; //20181002Delete
}
}
cur_dev = cur_dev->next;
}

// if (path_to_open) { //20181002Delete
// /* Open the device */ //20181002Delete
// handle = hid_open_path(path_to_open); //20181002Delete
// } //20181002Delete

hid_free_enumeration(devs);

return handle;
}

Best Regards
