Can't help feeling that Microsoft has spent scant attention to this Utility, hence fingers pointed in all directions. No of NEC/Renesas driver releases is indication that they are trying and there are others. Windows 8 is better, less attempts to fire up but my question is if it is chipset driver issue, would USB 3.0 work at all in WIN 7/8? Just checked Diskmark for USB 3.0 HDD from WIN 7 Seq Read 79.51 Write 47.18 All I can add is, keep trying, method is as detailed as I can make it Mike Williams. Thanks for the tip. Lenovo link is for: RENESAS-USB3-Host-Driver-21320-setup (very recent) Tried it, works after a few re-installs, as per above.

And can revert to it, after all, working well, except 'startup' glitches in WIN 7 / 8 Clue: WIN 8 came up with this error in Device Manager (USB Mass Sorage Device) 'Port Reset Failed' - when Flashdrive plugged in on BOOT/LOGON Feel that fix is close at hand, after all there are no catastrophic failures mid Full Partition Backups/Restores of 100Gb+ Some USB 3.0 Users have no problems, but there are many that do and it's worth questing for a solution (NOT apportioning blame) Mike Williams. Dear zircon99. I second your observation(s). Had problems with a USB 1.1 legacy device (printing dongle) on a mid-2011 HP laptop (with Renesas USB 3.0 chip). Recognized odd behaviour of printing dialogue after installation (correct installation that is, when using the USB3.0_allOS_2.1.28.1_PV utility, you will end up having TWO installations of the USB 3.0 driver package on top of each other, must remove/unistall the old one manually). Now for the new properties of the printing dialogue: it now has an option 'open device in administrator mode', which wasn't there before the update. BUT: you'll have to call up the properties twice (instead of once before), first time normally, second time in admin mode in order to reassign the USB connection (ports, are reassigned upon unplug-replug operations). Have more success with the printing dongle now on this laptop (uses an el-cheapo prolific chip) with WIN 7 x64, only on my other machine (WIN 7 32-bit with NVIDIA 8600GT graphics but intel chipset) it still will stall frequently when printing, requiring unplug-replug ops. Peculiar, isn't it? But they're definitely getting closer. Hope engineers will work this out for us (millions) of tech-unsavy users (chocolate reward promised for solution provider, honestly!).
