Sorry, a small typo in that last command line:

io-pkt-v4-hc -vvvv -ptcpip -dsmsc9500 vid=0x0424,did=0xec00,busno=1,devno=2,mac=001122334455 

The above results into "unknown error" even though vid/did/busno/devno are all correct...  

Does it work if you run io-pkt as follows:

io-pkt-v4-hc -dsmsc9500 busno=x,devno=y,mac=001122334455 -dsmsc9500
busno=a,devno=b,mac=001122334456
