You should mention that you're using libusb and the vendor's ftdi
library. Specifically, the kernels ftdi_sio driver is not involved.

Good that you were able to rule out the iommu, but you forgot to CC the
xhci maintainer (added Mathias again).
It could be good idea to include a link to thread with your initial
report as well:
