Thanks for your fast reply!

The Debian machine is a Thinkpad X240, ie Intel Haswell architecture
I tried libusb 1.0.22 and 1.0.23 with same result.

For information, I compiled a fresh git clone on my Archlinux box
(kernel 5.4.14) which worked without problem. Thus it could be either
a hardware or version issue, I will look into the logs later.
