Public bug reported:
This is a request to add support for a legacy touchscreen device
(NextWindow, USB ID 1926:0bce) to the `usbtouchscreen` driver in
Ubuntu's kernel packages.
This device is widely present in Windows 10-era all-in-one PCs,
including the Sony VAIO VPCL2290X and other OEMs. The Linux kernel
detects the device via `lsusb` and binds it to `hid-generic` or
`usbhid`, but no input events are exposed.
Adding the following line to `usbtouchscreen.c` enables proper input
event registration and restores full touchscreen function:
```c
{ USB_DEVICE(0x1926, 0x0bce), .driver_info = DEVTYPE_NEXTWINDOW },
This change has been manually tested with kernel 5.4 on Pop!_OS and confirmed
to enable touch input successfully.
Other similar NextWindow devices (like 1926:0003) are already supported
by the driver, so this ID is likely an overlooked omission.
With the transition away from Windows 10, many users are moving to Linux
on legacy hardware. Including support for this device in Ubuntu would
benefit a wide class of now-Linux-capable AIO PCs.
Tested device:
Vendor: NextWindow
USB ID: 1926:0bce
Host system: Sony VAIO VPCL2290X
Please consider reinstating or adding support for this device. If a
patch or DKMS module is preferred, I’m happy to contribute it.
