Here’s how to enable both Quanta Computer, Inc. ACER HD User Facing webcam and Lite-On Technology Corp. Wireless_Device on Linux. I’m using Pop!_OS 22.04 LTS.
Webcam: ID 0408:4033 Quanta Computer, Inc. ACER HD User Facing
wget https://raw.githubusercontent.com/Giuliano69/uvc_driver-for-Quanta-HD-User-Facing-0x0408-0x4035-/main/uvc_driver.c
sudo apt-get source linux-modules-extra-$(uname -r)
cd linux-6.0.12/drivers/media/usb/uvc/
mv uvc_driver.c uvc_driver.c.old
Copy the downloaded file to the current dir.
nano uvc_driver.c
Add a new section like this above the section describing .idProduct = 0x4035:
/*
* The Logitech cameras listed below have their interface class set to
* VENDOR_SPEC because they don’t announce themselves as UVC devices,
even
* though they are compliant.
*/
static const struct usb_device_id uvc_ids[] = {
/* Quanta ACER HD User Facing */
{ .match_flags = USB_DEVICE_ID_MATCH_DEVICE
| USB_DEVICE_ID_MATCH_INT_INFO,
.idVendor = 0x0408,
.idProduct = 0x4033,
.bInterfaceClass = USB_CLASS_VIDEO,
.bInterfaceSubClass = 1,
.bInterfaceProtocol = UVC_PC_PROTOCOL_15,
.driver_info = (kernel_ulong_t) &(const struct
uvc_device_info ) {
.uvc_version = 0x010a, } },
make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) modules
sudo cp uvcvideo.ko /lib/modules/$(uname -r)/kernel/drivers/media/usb/uvc/
Bluetooth: ID 04ca:3804 Lite-On Technology Corp. Wireless_Device
cd linux-6.0.12/drivers/bluetooth/
sudo nano btusb.c
add new entry:
{ USB_DEVICE(0x04ca, 0x3804), .driver_info = BTUSB_MEDIATEK |
BTUSB_WIDEBAND_SPEECH |
BTUSB_VALID_LE_STATES },
sudo make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
Reboot
