Unsolved - Virus TI 2 (kbd) USB problem

[Noatronic]

Hello

I'm having 2 strange USB problems when also the analog outputs are connected to my external soundcard, MOTU Ultralite mk2. This driver seem to be unstable.

• Sometimes, when Virus turned on I get a notification by Windows 7 there is no driver or an error with it. Without the analog outs connected it works fine (till now).
• Using the USB output in VC + analog outs connected: crackles in the usb sound + after a while the USB connection gets lost => The MIDI tranfers via 'Virus synth' doesn't work anymore. After closing Cubase, turning of/on Virus again, I get the same notification: no device.

I've tried everything: resetting the Virus, update again (via exit button + putting power cable in), re-instal the software, using different USB-port.
It's all been done by Access Music's advice and topics found on this forum. nothing really works.


Im using Cubase 6 on Windows 7 professional x64.


Any advice is welcome.


Kind regards
