Is the kernel too old for the XHCI emulator or am I missing something else?
The ancient kernel wasn't honoring bits 4:7 in register hcs_params2 (max. number of event ring segments) and tried to allocate 2 segments while QEMU only supports 1. That kills QEMU XHCI driver very early during initialization. I've patched the kernel appropriately (by replacing all occurences of ERST_NUM_SEGS with the computed allowed maximum number). XHCI is working now. Christian
