Studio 1747 / i7-720 and Firewire/Usb connection problems

Hi!

I tried in other threads, but now I´ll put it up here!

I cant get my firewire port connected to my TC Konnekt 48 audio interface - after a reboot it connects fine, but after less than a minute it freezes and then disconnect. Drivers are correct for windows 7 64 bit and other TC Konnekt users don´t have this problem??

Also the Usb ports are very very unstable and do not connect everytime I put devices in... a simple usb stick, only get pc contact every secomd time???

I tried to switch Ieee1394 drivers, from the pre installed to the (legacy) driver.. nothing helps..

All other things - sp far - runs smoothly!

Pls!! Do someone use this notebook for firewire connections - then pls tell me ig its realy works??

Best regds Peter
