With that bad work sequence error, are you running multiple pools with load balance or balance in cgminer? I have seen that before in that specific instance, and it has to do with the HF global work queue. Disabling multipool should fix that error.
Just on the one pool (bitminter). There are backup pools configured, but failover mode. I have now enabled failover-only additionally.
What kind of error do you get on the zombie?
Along those lines:
ERR: Asked to memcpy 0 bytes from usbutils.c _usb_read():3170
HFA : OP_USB_INIT failed! Operation status 20 (Regulator programming error)
HFA : hfa_send_frame: USB Send error, ret 0 amount 0 vs. tx_length 8, retrying
FAIL: USB get_lock not found (1:88)

Bus numbers don't match as the pastes are from different times.
I understand from the thread that the power required per board and USB is 300mA. The amount of boards x 300mA is just a bit above of what the hub power supply provides, so I got another hub on the way. The start-up sequence doesn't seem to matter.
Keep in mind that these Habaneros have operated fine at the previous owner's place. So unless the DHL guys provided a bumpy ride...
