Yes.
But sometimes I have to restart my PC. And than it takes up to 10 times to get them running.
I can see each Single 60GH/s at BitMinterClient. But some of them don´t show the temperature and don´t start.
What messages do you see in the log?

The 4 BFL SINGLE 60MH/s are on COM19, COM20, COM21, COM22
Only COM19 was found.
But it don´t start.
It is no problem to start mining with the CPU.
When I restart my computer then:
- maybe all of the 4 Singles are found, may be only a few ( let the devices connected )
- it is no problem if I do like this: start BitMinter, wait, connect the first BLF Single, wait, connect the second Single, wait ....
