As I read in drivers/usb/storage/uas-detect.h it seems that these
problems can hit some 174c:55aa devices and not others as it seems
they are difficult to detect
According to lsusb -v output, my MaxPower is 0mA... that would point
to a ASM1153 - with working uas support... but it's not really working
:/
I have tried on some different systems, and it seems it fails on
laptops (two Dell with Gentoo and kernel 5.3.11 and 5.2.8 and one
Asus with Windows10 (!)). While it seems to work fine with a
non-laptop systems like an Optiplex 7050 (with Gentoo and kernel
5.3.11).
I then tried to see if it was working on another non-laptop system (a
Precision 7920 running Ubuntu 18.10 with their 5.0.0-36 kernel)... but
it fails there too with errors like:

I am a bit lost then.. maybe it's an issue with the power of the USB
ports? :/ For example in the Ubuntu system, I have just tried to force
it to use usb-storage and it also fails... but going back to the
Optiplex system... it still works fine, like being a completely normal
device. But I don't see what could show my the difference between the
working system and the rest. In any case, I also post here how dmesg
output looks in the system that works fine when I connect the device
to see if maybe you see a difference
