Thanx, tho it turns out:
a) the FETCHENTRY:.. crash also happens without any device redirection
with FreeBSD 8.2 (at least) guests and ehci enabled (-readconfig
b) if I test this with your patch (working libusb_get_device_speed()
that doesn't just always return LIBUSB_SPEED_UNKNOWN) and redirecting
an usb 2.0 device with ehci enabled using usbredir then qemu
qemu: Warning: speed mismatch trying to attach usb device USB Redirectio
n Device to bus usb.0
and ignores the redirected device. So for now I have added a
#define IGNORE_LIBUSB_GET_DEVICE_SPEED to the (updated) preliminary
usbredir FreeBSD port,
so that usbredirhost_open() now always works with:
device_connect.speed = usb_redir_speed_unknown;
Question: do people also see this problem on Linux? This post has
an usage example:
Or is the problem just that with the example usage,
sudo usbredirserver 045e:0772
qemu ... \
-readconfig docs/ich9-ehci-uhci.cfg \
-chardev socket,id=usbredirchardev,host=localhost,port=4000 \
qemu 0.15.0 tries to attach the redirected usb 2.0 device to the
uhci bus instead of to the ehci one and if yes, how can I fix that?
