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.

not sure about the shuttle, but i can tell you i run my iMac G4 keyboard and a logitech optical mouse through a hub (as well as sound sticks, digital camera, XSKey, and printer). if you're having conflicts, it's best also to turn off any devices you don't need while using the 428.
