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
