Is there a way to slow down the USB Blaster Cable operation?

In my case, the JTAG is routing is very short, less than 15mm in length, good GND and DC connection, but still there ate some problems with SignalTap.

More than that - it behaves slightly different with different versions of Quartus II...

Sometime in the past i had read about different driver, substitute to the Altera one, but i can't find it on the net now...
