were you able to locate the driver src code?
have you tried seeing who is the maintainer for code?
can you locate a driver log and crank up its debug log level?
does a working driver anywhere to show it's future potential is?
is this a personal effort or code education project?
curious thx, ...

Dear Fedora Experts,
I've just bought an Ipevo VZ-X document camera and I've some hard times to
have it running with my Linux Box (a dell precision m6800 running Fedora 31).
This camera can be connected to the the laptop both via usb and wifi.
I've tried both without much luck.
When connected via usb the system (most of the times) correctly recognize it:
> lsusb
Bus 003 Device 113: ID 1778:d120 IPEVO Inc. IPEVO VZ-X
But it doesn't show up in any tool I tried (Zoom, Teams, Skype, Kamoso,
OBS, Cheese, guvcview, etc.) nor in the system settings.
I wrote "most of the times" because it needs several turn on/off to be
recognized.
When it is recognized dmesg says:
[25080.302042] Code: Bad RIP value.
[25082.706544] usb 3-2: 9:2: cannot get min/max values for control 2 (id 9)

In the remaining cases, I get from dmesg:
[32124.861677] Code: Bad RIP value.
[32127.116392] usb 3-1: new full-speed USB device number 122 using xhci_hcd
[32127.230305] usb 3-1: device descriptor read/64, error -71
When connected via wifi, I can access it through its web configurator and I
can test its functionality but only on the browser (chrome) still it doesn't
show up in any other application.
Ipevo provides a version of its visualization software for linux (ubuntu)
https://ipevo-api-cms.s3-us-west-1.amazonaws.com/software/visualizer/download/Linux/Visualizer_linux_1.0.5.33.zip
I've tried to convert it with alien but it fails
> alien -r visualizer_1.0.5.33_all.deb
...
RPM build errors:
Arch dependent binaries in noarch package
But I'm pretty sure this will not help with the general problem.
Any idea/suggestion on how to have this working?
Thank you in advance for your help
Walter
