Also be aware that usb-redir relies on chardev flowcontrol working,
which it does not upstream! See for example here for the chardev flow
control patch set which RHEL / Fedora carry:
http://cgit.freedesktop.org/~jwrdegoede/qemu/log/?h=qemu-kvm-1.2-usbredir&ofs=50
And then the first 13 patches after: "Merge tag 'v1.2.0'"
Oh, and also, if you're running qemu git master, make sure you've:
http://cgit.freedesktop.org/~jwrdegoede/qemu/commit/?id=81e34f5973d8d6a1ef998a50c4a4bf66abb3b56b
I used qemu-kvm-1.2-usbredir^ (the last commit is apparently broken -
copy&paste bug?).
Yeah, that has been fixed now.
I'm getting this right after typing cat /dev/ACM0 in
the guest. It's an endless stream, and so is the output in the guest
although there should be nothing to dump (that's the proper behaviour on
the host).
Hmm, can you try commenting out line 1608 of hw/usb/redirect.c:
usb_ep->pipeline = true;
And see if that helps. If it does not help, please bump the debug level to 5
(this will also make it log packet contents), and then generate another log, and
then it is time to dive into the ACM protocol to see what is happening...
As it looks like now, I was just using the wrong test on the guest side.
Retried this morning briefly with a terminal program, and it was all
fine, even when forwarding from host-ehci to guest-uhci (with my broken
patch), even when using current QEMU git head. Sorry for the noise
Ok, so to be clear: this is solved now, right ?

Hans
