So I built it without errors. Signed it, and done all things as they should be.

Now my dmesg shows a bunch of [ 453.163918] usb 2-1: Nonzero urb status, 0, and I don't know what to do about it.

Hi!

Same error here, did anyone find a solution?

It's just a spam of successful USB Request Block transfers. The actual problem seems to be

[ 1368.860913] i2c i2c-12: Cannot get monitor status (-5)

Tested with a slightly patched driver so that it compiles on kernel 6.14.4

I got it as far as modesetting monitor to the "default" resolution, but monitor edid does not get pulled. Something is wrong in the it66121 driver with the way it accesses i2c or the regmap

I'd be happy to help if the original developer can clear things up, but for now I've hit a roadblock.
