That is a transfer descriptor for isochronous split transfers (siTD).
Split transfers are used to support 1.1 devices behind 2.0 hubs. There
is no USB 2.0 Hub emulation in qemu and also no split transfer emulation
in EHCI, thats why the failure.
/me wonders what FreeBSD tries to do here? This triggers even without a
single device connected and I can't think of a reason to use a siTD in
that case ...
Nevertheless qemu shouldn't fail like that.
cheers,
Gerd
