-qemu-xhci device should detect if libusb host supports streams
-
-When using USB passthrough with the qemu-xhci (and nec-usb-xhci), streams are enabled by default, but if the host xHCI controller doesn't support them, it will trigger hard-to-debug UAS guest errors.
-
-This should be possible to detect since the kernel returns ENOSYS (errno 38) when xhci host controller does not support streams:
- libusb: error [do_streams_ioctl] streams-ioctl failed error -1 errno 38
- qemu: libusb_alloc_streams: -99 [OTHER]
-
-Maybe libusb should return a dedicated error instead of LIBUSB_ERROR_OTHER in this case, but qemu does not handle any other error code anyway.
-
-Just trying to enable streams before enabling them in qemu should do it. I don't know if it should be done in hcd-xhci.c, host-libusb.c or elsewhere, but this would be detectable at launch instead of a static option true/false, maybe a ternary with auto would be better.
-
-The QEMU project is currently considering to move its bug tracking to
-another system. For this we need to know which bugs are still valid
-and which could be closed already. Thus we are setting older bugs to
-"Incomplete" now.
-
-If you still think this bug report here is valid, then please switch
-the state back to "New" within the next 60 days, otherwise this report
-will be marked as "Expired". Or please mark it as "Fix Released" if
-the problem has been solved with a newer version of QEMU already.
-
-Thank you and sorry for the inconvenience.
-
-
-This is a suggestion that would really help anyone using trying to use xhci passthrough on a platform without streams.
-
-
-This is an automated cleanup. This bug report has been moved to QEMU's
-new bug tracker on gitlab.com and thus gets marked as 'expired' now.
-Please continue with the discussion here:
