This may be related.
I am trying to use USB-PCIe cards based on the Renesas 720202 chipset
with an Intel dual Xeon 4114 server. 720202 devices are visible in

Hi,
It looks like someone attempted a fix, but it was beset by a typo. I fixed the
typo and compiled the kernel and the issue was resolved. I detailed the typo in

Thank you,
-Jeff
Yeah it's a typo.
