as the messages says, your Host do not support DirectPath IO.

Intel Directed I/O or AMD IOMMU should be enabled in the BIOS of the host, if these options are not there in BIOS, then you cannot enable DirectPath IO in ESXi hosts.

Refer below KBs/docs -

Enable USB Support for ESXi with VMDirectPath
