Support try/except imports

[mikelei8291]

Describe the bug
When using the evdev library, I noticed that methods defined in the parent EventIO class of the InputDevice class were not resolving, because the import of the parent class is using a try/except block to try to import the async version of it first:

try:
    from .eventio_async import EvdevError, EventIO
except ImportError:
    from .eventio import EvdevError, EventIO

Code or Screenshots

from evdev import InputDevice

device = InputDevice("/dev/input/event3")
device.async_  # try trigger autocomplete here

Notice that none of the async_* methods shows up in the autocomplete.

evdev 1.9.3 is used in this example.

VS Code extension or command-line
ms-python.python: 2026.4.0
ms-python.vscode-pylance: 2026.1.1

Extra Notes
Also, I noticed that if I switched the language server from Pylance to Jedi in VSCode using the python.languageServer option, the good old Jedi will resolve these methods just fine.
