Dell Vostro 3750 - USB 3.0 Troubles

I have a 3 monthold Vostro 3750, I7, 1GB nvidia graphics, works great, coolest running laptop I have ever seen.  When I start the computer the usb 3 ports work for several minutes then shuts itself off and even my mouse will not work on them. When I plug the same mouse into the usb 2 port they work fine but the 3.0 ports will not work until I reboot the computer. I have loaded the latest Renesas USB 2.1.25 driver and there still appears to be no solution to the problem.  The usb 3.0 issue seems to be a common problem, at least on Vostro machines. With 2 USB ports out of a total of 3 being non-functional, it is getting to be a nightmare using my USB peripherals, which i have managed to circumvent with 2 USB 2.0 hubs serially connected to each other.

I hope someone has the right solution to this USB 3.0 problem.

Uncheck the box in the device manager  that says allow windows to turn this device off to save power.  Do that for all usb Root hubs.

Re: Dell Vostro 3750 - USB 3.0 Troubles

I've noticed several USB 3.0 issues were reported  on i7 nvidia equipped XPS and Vostro laptops.

Curious if any USB 3.0 issues were found on intel graphics 3000 or i3 equipped computers?

I have a 3750 i3 intel 3000 on order and am willing to do some simple tests on a virgin machine if anyone is interested.

Re: Dell Vostro 3750 - USB 3.0 Troubles

Been running usb 2.0  ( mouse, keyboard, SD card and HDD)  in my i3 intell 3000 vostro 3750  usb 3.0 ports w/o any problems.

Only problem I've found so far is I failed to a get backlit keyboard. Could have sworn I saw backlit before  adding Vostro to cart. Bummer.

swade56. I understand you have to unplug usb 3.0 device to find OS . Have you tried to disable usb boot in BIOS? Perhaps there is a bootable image on your USB 3.0 device thats confusing Win 7?

I have just had a client with one of these models. There is a design flaw on the motherboard. If it is still under warranty then send it back. You shouldn't have to do any of the things suggested in these post.

Re: Dell Vostro 3750 - USB 3.0 Troubles

My Vostro 3750 i3-2330 Intel HD 3000 graphics does not have a USB 3.0 problem w/ USB 2.0 devices.

I use USB 2.0 mouse in USB 3.0 port all the time w/ no problem.

I don't own a USB 3.0 device for testing.

Re: Dell Vostro 3750 - USB 3.0 Troubles

I experienced similar problems, when trying to connect two identical USB 3.0 disks (working as a software RAID1).

The disks switched off shortly after connection and only after reboot (without those disks) and reconnection they were visible again (for a short time).

Finally I've decided to upgrade the uPD720200 firmware and the drivers: www.station-drivers.com/.../renesas.htm

It helped a little. Now the system works with ONE USB 3.0 disk connected (both in Windows and in Linux).

However I'm still not able to use two disks simultaneously.
