"Errno Device not found"

[e34rrsff]

I'm not sure how to fix this error

TimeoutError: [Errno Device not found] -5: 19

[mpi3d]

Could you give more info about the sensor. Also can you provide the full output of the program?

[e34rrsff]

I'm pretty sure it's the 55b4, but it doesn't get listed in lsusb or lspci. I have the Lenovo Yoga C940 and I flashed some firmware to get the speakers working.

Here's the output:

If the device doesn't show in your lsusb, this mean that the device is not present on your laptop.
Also, if your device doesn't show in your lsusb, this script will not work anyway. This is why the program raise TimeoutError: [Errno Device not found] -5: 19

So maybe your device is an SPI one.
Could you provide the result of /sys/bus/spi/devices?

[e34rrsff]

There's nothing in the directory

[mpi3d]

Your device doesn't seems to be a Goodix one then.
This repo is only for Goodix devices.
So I can't do much more then.

[e34rrsff]

I've confirmed that it is definitely is a Goodix sensor. On the support page for my laptop, it has a Windows driver with the names "Goodix" and "Synaptics". It also doesn't get detected in Windows for some reason, even though it worked before...

[mpi3d]

Well I can't do anything as long as the device doesn't show up in your lsusb.

[e34rrsff]

So, I guess it was something with the newly flashed BIOS. There's just lots of options in it, and none of them say anything about a "fingerprint sensor," just some device IDs and some stuff I don't really know about, but it works now. Thanks for the help.

I have a same error.
