[sane-devel] device i/o error

[Luca Forina]

I'm trying to scan with my new printer Hp LaserJet MFP M28-M31 but I always
get this error:
error: SANE: Error during device I/O (code=9)
I've installed hplip hplip-plugins and any other dependencies listed in
hp-check but without luck.

hp-scan log with sane debug enabled:

hp-check log:
https://pastebin.com/raw/RegyJ6B9

any hints?
