Does it have the same internal software problems as the Tube?
Or is the stratum implementation fixed this time?
Hopefully your custom cgminer version doesn't have the same problems also.
The cgminer differs from the main branch in only the communication to the device
and some part of the USB driver. Other parts are not modified.
It would also be open source.
So this is a nice way of saying: Yes, it indeed has the same bugs.
