kernel panic with pure usb2umass pluged on pure usb1only motherboard port

[Mathieu PREVOT]

Hello,

my kernel panics when I plug a pure USB2 umass. My motherboard has a 
VIA KT200 and has only USB1 ports.
However, everything works perfectly with USB1 and USB1&2 umass.
I used a custom kernel 5.4 but I noticed that behavior since 5.2.1. I 
not able to provide the output.

Is it a known issue ?

Regards,
