I reply to myself because I was able to
solve it thanks to this post :

I have to pass all the USB controller sharing the same RMRR to the
same domU to make it work.
Adding this to the domU configuration :
'00:14.0,rdm_policy=relaxed',
'00:1a.0,rdm_policy=relaxed',
'00:1d.0,rdm_policy=relaxed',
and I have now this in the logs, but the VM works fine :
(XEN) [VT-D] It's risky to assign 0000:00:14.0 with shared RMRR at
bdbe3000 for Dom4.
(XEN) [VT-D] It's risky to assign 0000:00:1a.0 with shared RMRR at
bdbe3000 for Dom4.
(XEN) [VT-D] It's risky to assign 0000:00:1d.0 with shared RMRR at
bdbe3000 for Dom4.
