The kernel has a module for this, "hid-primax", which re-orders the
received HID reports to make them compliant.

HID: support primax keyboards violating USB HID spec
Primax keyboards with the issue this driver addresses report modifier
keys as in band key events instead of as out of band modifier bits,
resulting in the modifier keys generating key up events immediately
before the keys they are intended to modify. This driver rewrites
the raw report data from such keyboards into USB HID 1.11 compliant
report data. It only matches the USB vendor and product IDs for the
keyboard it has been tested on. Since there are several keyboards,
notably a number of laptops and folding USB keyboards known to have
similar unresolved problem reports, the list is expected to grow.

$ git describe --contains f6a04605f3038
v3.2-rc1~187^2^2~2
Currently the driver only supports the device ID 0461:4e05 and will need
the IDs of other devices adding in order to work with them.
# extract from drivers/hid/hid-primax.c
static const struct hid_device_id px_devices[] = {
{ HID_USB_DEVICE(USB_VENDOR_ID_PRIMAX, USB_DEVICE_ID_PRIMAX_KEYBOARD) },
{ }
};
$ grep PRIMAX drivers/hid/hid-ids.h
#define USB_VENDOR_ID_PRIMAX 0x0461
#define USB_DEVICE_ID_PRIMAX_MOUSE_4D22 0x4d22
#define USB_DEVICE_ID_PRIMAX_KEYBOARD 0x4e05
#define USB_DEVICE_ID_PRIMAX_REZEL 0x4e72
Collecting additional IDs and adding them would be the best action to
take.

Bug description:
Hi
I got an issue on Ubuntu 18.04 with latest packages.
uname -a:
Linux MyLaptop 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018

product: Lenovo USB Receiver
vendor: Lenovo
physical id: 3
bus info: usb@1:3
version: 1.05
capabilities: usb-2.00
configuration: driver=usbhid maxpower=100mA speed=12Mbit/s
My wireless keyboard is not working, Ubuntu only recognize some
special keys (Super, Ctrl, Shift, Alt)
This is a Mouse+Keyboard combo using a wireless receiver by usb:
lsusb:
Bus 001 Device 005: ID 17ef:609b Lenovo
Mouse works fine, and in Windows 10 it works with no issues.
I found multiple reported problems with this keyboard in other distros (and
from Asus too, as the real manufacturer is Primax Electronics).

There is a workaround (I still didn't tried) but it needs to compile an
specific driver.

There is already a kernel report about this.
