Hi, I installed the blinkstick python module in a virtual env. Can’t even get the help or info commands to run ``` Φ blinkstick zsh: permission denied: blinkstick ``` With sudo directly: ``` sudo python3 blinkstick Traceback (most recent call last): File "blinkstick", line 4, in from blinkstick import blinkstick ModuleNotFoundError: No module named 'blinkstick' ``` Installing it straight to the system (both with sudo and without) results in the same errors ---

1st one, chmod +x blinkstick 2nd one, try: [https://github.com/olafrv/blinkstick\_square](https://github.com/olafrv/blinkstick_square) ---

Neither work. There is no blinkstick to +x to. Unless you mean the blinkstick.py file in the package. The other project just outputs this when trying to run ```auto 17:07 PM Φ uvicorn server:app Traceback (most recent call last): File "/home/uname/operational/code/doblink/blinkstick_square/blink/bin/uvicorn", line 8, in sys.exit(main()) ^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/click/core.py", line 1157, in __call__ return self.main(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/click/core.py", line 1078, in main rv = self.invoke(ctx) ^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/click/core.py", line 1434, in invoke return ctx.invoke(self.callback, **ctx.params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/click/core.py", line 783, in invoke return __callback(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/uvicorn/main.py", line 416, in main run( File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/uvicorn/main.py", line 587, in run server.run() File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/uvicorn/server.py", line 61, in run return asyncio.run(self.serve(sockets=sockets)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/asyncio/runners.py", line 190, in run return runner.run(main) ^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/asyncio/runners.py", line 118, in run return self._loop.run_until_complete(task) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "uvloop/loop.pyx", line 1517, in uvloop.loop.Loop.run_until_complete File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/uvicorn/server.py", line 68, in serve config.load() File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/uvicorn/config.py", line 467, in load self.loaded_app = import_from_string(self.app) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/uvicorn/importer.py", line 21, in import_from_string module = importlib.import_module(module_str) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/importlib/ __init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "", line 1204, in _gcd_import File "", line 1176, in _find_and_load File "", line 1147, in _find_and_load_unlocked File "", line 690, in _load_unlocked File "", line 940, in exec_module File "", line 241, in _call_with_frames_removed File "/home/uname/operational/code/doblink/blinkstick_square/server.py", line 27, in bs = blinkstick.find_first() ^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blinkstick_python/blinkstick/blinkstick.py", line 1585, in find_first return BlinkStick(device=d) ^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blinkstick_python/blinkstick/blinkstick.py", line 218, in __init__ self.open_device(device) File "/home/uname/operational/code/doblink/blinkstick_square/blinkstick_python/blinkstick/blinkstick.py", line 823, in open_device if self.device.is_kernel_driver_active(0): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/usb/core.py", line 1107, in is_kernel_driver_active self._ctx.managed_open() File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/usb/core.py", line 113, in wrapper return f(self, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/usb/core.py", line 131, in managed_open self.handle = self.backend.open_device(self.dev) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/usb/backend/libusb1.py", line 804, in open_device return _DeviceHandle(dev) ^^^^^^^^^^^^^^^^^^ File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/usb/backend/libusb1.py", line 652, in __init__ _check(_lib.libusb_open(self.devid, byref(self.handle))) File "/home/uname/operational/code/doblink/blinkstick_square/blink/lib/python3.11/site-packages/usb/backend/libusb1.py", line 604, in _check raise USBError(_strerror(ret), ret, _libusb_errno[ret]) usb.core.USBError: [Errno 13] Access denied (insufficient permissions) ```
