Cubase Sx2 & Us-428 Problem, constant interuptions Options

[hani]

I just downloaded the latest US-428 driver from Tascam.com. i can control SX 2 now fine.
however, im now faced with a new problem.
"Beach Ball of Death" (as some sx users called it) keeps interupting the work flow and hangs for a while then in some cases it crashes the program.
in the begining i was not sure what was causing the Ball to appear systematicaly every few min. it only stoped appearing after i turned off US-428. Now i dont even bother using the US-428 since I only used it to control sx2. not worth the delay.
BTW: im using OS 10.2.8 and the latest sx update.
so im not sure if there is a general problem with SX and USB audio devices.

First thing to try is plugging direct. I know that Griffin hub was designed specifically for audio, but I do remember back when the Tascam forums were around that the general advice was to avoid using a hub of any kind. I have no problems with my 428 for control, audio and MIDI using only 384RAM.
