Bug ID: 54838
           Summary: Wine names dinput devices (and likely other HID
                    devices) incorrectly
           Product: Wine
           Version: 8.5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dinput
          Assignee: wine-bugs@winehq.org
          Reporter: burneddi@protonmail.com
      Distribution: ---
Joysticks and other dinput devices have the wrong instance and product names on
Wine as compared to Windows.
I will illustrate the problem by example. I have a joystick that reports the
following information:
$ udevadm info -n
/dev/input/by-id/usb-VKB-Sim_©_Alex_Oz_2021_VKBsim_Gladiator_EVO_R-event-joystick
[...]
E: ID_MODEL_ENC=\x20VKBsim\x20Gladiator\x20EVO\x20\x20R\x20\x20
E: ID_VENDOR_ENC=VKB-Sim\x20©\x20Alex\x20Oz\x202021
[...]
Under Wine, this device is identified by apps as well as the Game Controllers
interface in the Wine Control Panel as "VKB-Sim © Alex Oz 2021  VKBsim
Gladiator EVO  R". On Windows it is identified as " VKBsim Gladiator EVO  R".
In other words, the Wine's dinput's tszInstanceName and tszProductName fields
contain the vendor field concatenated with the model field, whereas it should
only contain the model field.
This breaks some applications.
I discovered this issue when Star Citizen failed to save configuration for the
joystick, which turned out to be because of the copyright symbol in the device
name as exposed by Wine. While config saving breaking due to the copyright
symbol is technically a bug in the game, it does not manifest on Windows,
because on Windows the name of the instance/product does not include the vendor
part and therefore does not include the copyright symbol.
It is also possible that game controller configuration software might be
tripped up by this discrepancy.
