complete system hang/freeze when connected a device / tried to do file operations with it filesystem detected as RAW (it is NTFS everytime) i also tried every driver on win 7 32 / 64, with latest firmware for uPD720200 controller.
NEC RENESAS USB 3.0 DRIVER DRIVERS
I allready tried this 2.1.28.1 you submitted (which is unfortunately displayed as 2.1.28.0 after installing, whats wrong here?), with the last firmware (3034 for uPD720200) as well as the firmware before with all (other) RENESAS drivers available (i guess - found here Station-Drivers - Renesas/Nec). Faulty or marginal Power Supply Units can be responsible for all sorts of unusual problems like this but if you're having difficulty tracking down the culprit, it'd be worth taking the PC to your local computer store and asking them to diagnose whats wrong.
There's something else going on with your build to cause these problems and the fact that your replacement board behaves exactly the same way only confirms this for me. I now have a PCIe USB 3.0 adapter card in my PC and its working fine with the latest drivers. I'd had problems with my onboard USB on an older board and a wifi dongle that wouldn't work reliably but a cheap NEC USB 2.0 adapter card fixed things and got it all working as it should be. So you've received a brand new board but there's no customer service - how did you get the new board then? How do you explain that some people are having no problems at all with their same model board? The people behind this USB 3.0 hardware used to be known as NEC and they established a reputation for the best quality USB 2.0 add-on PCI cards.
I'm fierce about Intel, there is no custumer service, I tell it to all my contacts about the very poor Intel service! Today I've received a brand-new DH67CF board, but it does have the same problem as before.
