Amazon Basics USB mice not working on rpi, updated

Hi folks,
this message is an update of [1].

The effects of the issue, which arise on 9front running on a rpi, are:
- inability to effectively use any of the 3 mouse buttons (no popover, =
no window resizing)
- rio=E2=80=99s text content is flickering while the mouse is moving =
(note, the mouse IS moving at least)

I followed ori instructions [2] asking me to try the mouse on a 386 =
machine. I finally managed to start 9front on an old macbook; I found =
other issues there that might be discussed another time, but what its =
relevant here is that the mouse there is working!

I investigated a little further by looking at the output of /dev/mouse, =
maybe I found something. Here are some example lines
m 549 183 0 1042100 # 9front, macbook
m 681 398 0 2910970 # 9legacy, rpi
m 614 375 8 985430 # 9front, rpi

The 3rd column (tells which buttons were pressed and the wheel rotation =
right?), in the 9front case on the rpi only, keeps on switching from 16 =
to 8 each read. This does not happen on the other two setups.

I=E2=80=99m running the latest image release (no thinkpad) with =
cinap=E2=80=99s [3] patch.
