This line was after I added hostbus and hostport numbers. aqemu leave them empty:
usr/bin/qemu-system-x86_64 -monitor stdio -k de -machine accel=kvm -m 4096 -no-fd-bootchk -fda /home/user/qemu/Win7/floppy -cdrom /home/user/qemu/cd.iso -hda /home/user/qemu/Win7/hda.qcow2 -hdb /home/user/qemu/Win7/acronis.qcow2 -boot once=c,menu=on -net nic,macaddr=00:ef:55:f9:d7:d9,model=rtl8139 -net user -usb -device usb-host,bus=usb.0,hostbus=,hostport= -rtc base=localtime -name "Win7"
By the way this will not change the error message.

I made a typo because must retype from console because could not C&P:
usr/bin/qemu-system-x86_64 -monitor stdio -k de -machine accel=kvm -m 4096 -no- fd-bootchk -fda /home/user/qemu/Win7/floppy -cdrom /home/user/qemu/cd.iso -hda /home/user/qemu/Win7/hda.qcow2 -hdb /home/user/qemu/Win7/acronis.qcow2 -boot once=c,menu=on -net nic,macaddr=00:ef:55:f9:d7:d9,model=rtl8139 -net user -usb -device usb-host,vendorid=0x0c4b,productid=0x0500 -rtc base=localtime -name "Win7"
