Additional info:
Same issue on
host:
qemu-kvm-rhev-2.6.0-28.el7_3.9.x86_64
kernel-3.10.0-679.el7.x86_64
guest:
kernel-3.10.0-514.25.2.el7.x86_64
It is not a regression.
Hmm, behaviour looks sensible to me. Only one instance of the device actually works. The second instance throws an error (can't set config #1), because the device is busy. So only one storage device (/dev/sdx) shows up in the guest.
Reading the usb descriptors works even in case the device is in use, so lsusb shows both instances (and lsusb on the host shows the usb devices too even when they are in use by a guest).
