Windows 7: USB device not recognized - Help!

04 Nov 2009   #21

Windows 7 Ultimate

I have a similar problem but it seems to be the USB itself and its name when plugged in is Unknown Device and I have tried with several computers, one with XP, one with Vista, and one with 7

so it might be the usb

See my post at the bottom of this for how I fixed that one:
iPod touch will not sync in Windows 7 -

I'm thinking there is a USB issue on 64-bit Win7, maybe with certain motherboards (I'm also on an nVidia chipset).


P.S. I also had no probs under 32-bit XP
Hey ya'll,

Try Phil's solution. It worked for me perfectly, USB 2.0 works and ipod no freeze.

Thanks phil

Same problem Windows 7 sparked the problem...

This is happening to me also. After installing Windows 7 64b, the sync
freezes after a couple of songs transfers on my Ipod (normally, errror code
0xE8000065). Tried everything imaginable: Itunes reinstall, execute
with compability to VIsta, energy safe mode off to USB ports/hubs,
cable change, restore Ipod. I have a Acer Aspire M3641, lastest ITunes

version, latest software on Ipod. Now my external drive also freezes
in the middle of a backup even if I'm not using a usb hub. Please
Microsoft, Apple, Intel, whoever, WAKE UP !!! This is now a major
problem. Please see Intel, Apple, Microsoft probe iPhone-Windows sync bug and Getting error 0xE8000065 when sync’ing? | Talk iPhone - iPhone News Blog and Forums and
many more articles and claims. Will try this "solution" though...

a fix

i have just installed windows 7 and had the same problem on my new samsung lap top r610, i just found a fix that worked for me, just turn off your laptop or desk top and un plug it from the mains for a 1 min, then plug it back in and start it back up a you should see windows re-install the driver, it was that simple for me hope it works.

Very simple solution

Please unpower your motherboard. So switch of your power supply at the back of your system or remove the power connector for 1 minute. That often resets your USB hub on your motherboard. It worked for me anyway!

usb device not recognized....over and over

It seems like there's some differences in the usb problems talked about here. Here's mine:
All of my usb ports work. Yet I get these "USB Device Not Recognized..." notifications at random times (the sound effect is french horns atm, better than the banjo!!). Some days I don't get any pop ups. Most days I get about 20-30 notifications per hour! If I click the "x" the pop up comes right back. If I click the pop up, they show the "unknown device" to be fixed. All avenues for fixes are dead ends so far. I tried unplugging from the wall, clearing cmos, uninstalling devices, following Windows 7 fixes...i even checked the "do not show me usb errors" in the usb port properties advanced tab! And they still pop up! I think next I'll look into that itunes fix idea from a previous post, other than that, I'm at a loss.
