The PixArt OEM mouse disconnets/reconnects every minute on Linux. All contents of dmesg are repetitive: [ 1465.810014] usb 1-2.2: USB disconnect, device number 20 [ 1467.431509] usb 1-2.2: new low-speed USB device number 21 using xhci_hcd [ 1467.654982] usb 1-2.2: New USB device found, idVendor=03f0,idProduct=1f4a, bcdDevice= 1.00 [ 1467.654985] usb 1-2.2: New USB device strings: Mfr=1, Product=2,SerialNumber=0 [ 1467.654987] usb 1-2.2: Product: HP USB Optical Mouse [ 1467.654988] usb 1-2.2: Manufacturer: PixArt [ 1467.699722] input: PixArt HP USB Optical Mouse as /devices/pci0000:00/0000:00:07.1/0000:05:00.3/usb1/1-2/1-2.2/1-2.2:1.0/0003:03F0:1F4A.0012/input/input19 [ 1467.700124] hid-generic 0003:03F0:1F4A.0012: input,hidraw0: USB HID v1.11 Mouse [PixArt HP USB Optical Mouse] on usb-0000:05:00.3-2.2/input0 So add HID_QUIRK_ALWAYS_POLL for this one as well. Test the patch, the mouse is no longer disconnected and there are no duplicate logs in dmesg.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
