Bug: IIO IMU errors out when undocking device. #102

Open pastaq opened 4 months ago

When un-docking the AYANEO 2S I noticed this error pop up.

[2024-05-20T02:09:44Z ERROR inputplumber::input::source::iio::iio_imu] Error running IIO Driver: Nix(ETIMEDOUT)
[2024-05-20T02:09:44Z ERROR inputplumber::input::composite_device] Failed running iio device: "ETIMEDOUT: Connection timed out"

This could possibly affect other devices. I will test more devices to find out. The AYANEO 2S has a BMI260 IMU that uses a BMI160 ACPI ID.

When an IIO device is removed we should remove it from the list of devices we have checked in our discovery loop so it can be rediscovered.

This bug also occurs if you adjust the scale or sample frequency of the IMU as noted in the testing for #115 and is looking more like an issue with the hardware implementation on that specific motherboard. Affected models so far: AYANEO 2, 2S, Geek, Geek 1S

udev events are not triggered when the device is undocked. We should find a way to use udev-rs to verify if the gyro has actually been removed, and if not, attempt to reopen the channel for some maximum number of attempts before killing the source device.
