I use Windows 7 SP1 Ultimate edition with all the latest patches and updates (as of November/10/2011) installed. My problem is that whenever my system resumes from sleep none of my USB devices work. Removing and replacing the devices does not help. The only way to get things working after resuming from sleep is to restart the whole system. Ideas anyone??

Hi, Please update your BIOS and chipset driver to the latest versions. Meanwhile, you may check if you have the same situation with following article: Clicking USB mouse or pressing USB keyboard while going into standby may prevent mouse/keyboard from waking system Alex ZhaoPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Both my Bios and my chipset driver are the latest revisions Second issue also not relevant to me. My system "wakes" no problem, it's just that all my USB ports are dead till the next restart. This is just speculation but I think something about Windows power settings could be causing the USBs not to come out off sleep mode once they enter it. Not too sure how to go about checking/remedying this though.

Hi, From this perspective of windows power settings, I suggest you check USB power options: 1. Open Power Options. 2. Change your plan settings, Click Change advanced power settings. 3. Scroll down to USB settings option, expand it, and then expand USB selective suspend setting. 4. Set this setting as Disable. Meanwhile, please open Device Manager, in the Device Manager Dialog box, expand Universal Serial Bus controllers, right-click USB Root Hub, and then click Properties. In the USB Root Hub Properties dialog box, click the Power Management tab. Clear Allow the computer to turn off this device to save power check box.

I gave it a shot. Did exactly as you said but come time to resume from sleep and the USB's were dead on cue! I really thought it would work this time but I ended up having to restart all over again...guess my suspicions about the power settings were incorrect.

Hey did you manage to find a solution for this? I've got the exact same problem, the funny thing is clicking the mouse button or pressing my keyboard keys actually wakes up the PC, but once awake they don't work at all, none of the USB devices do :(

Hi, I suspect this is related to certain USB driver (usbhub.sys, Usbport.sys), although you have installed Windows 7 Service Pack 1, I suggest you install the following update or hotfix for test: Binary files in some USB drivers are not updated after you install Windows 7 SP1 or Windows Server 2008 R2 SP1 USB devices that are connected to a computer may not work after the computer is idle for more than one hour Windows 7 or in Windows Server 2008 R2 Alex Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I ran the msi installer patch. The program told me that the patch was already installed on my system...

I ran the msi installer patch. The program told me that the patch was already installed on my system. Incidentally I had some time to kill today I decided to dual-boot install my old Windows XP Pro SP3 alongside my current Windows 7 system. The 32bit edition XP Pro was not even able to pick half of my system ram but it ran like stink and went to and out of sleep mode with nary a glitch. Methinks I am going to keep the XP Pro for a bit now... Any other ideas about what might be wrong with the Windows 7?

This started happening randomly to me just this past week or so. It doesn't happen all the time, and mostly with the USB keyboard/mouse at work, haven't noticed it happen when I go home and connect up the keyboard/mouse there. Right now, no other USB devices work, originally I thought it was just the keyboard that had the issue, but I hardly ever connect more than that at work to the USB ports. I confirmed with my iphone and flash drive that it was all USB connectivity (both ports). Macbook pro running win7 64bit sp1 with 8G RAM Rebooting usually brings it back. Hope someone has a solution, it's a pain! --D

Consider yourself lucky this is has been a regular feature for me since day one. Initially ignored the situation for a bit by preventing my system from going into sleep mode but then because my system is a laptop not being able to conserve power by going into sleep mode has consequences on my battery when I am not plugged in. My first instinct was to run a complete factory restore but that didn't do me any good. Went online and searched. I learned that it was pretty common for Windows 7 users to have some issue or the other with resuming after sleep all the way back to RC and RTM editions of the program but wasn't able to find any satisfactory cure. Most forums trail off with the person concerned being told to wait for next update to be released whether RTM, Final or even SP1!!! I am cautiously optimistic but realistically it's possible that I am just going to have to settle with being one of the unlucky ones. Here's hoping Alex (or some other expert on the forum) can figure this out.

Just curious... is there any other power manager software installed such as what is bundled with Dell, Lenovo, HP etc? I have found these programs have a tendency to conflict with the Windows power settings. If you do have that manager bundled in there, try taking it off. Conversely, try adding it back on if you did take it off. See if that changes anything. Maybe a file/registry entry got corrupted in the process of converting over to the Windows power manager. Does this also do this after hibernation?

@Fazil: I do still suspect that my problem is somehow related to power management. I've read through the article. It claims that the resume problem that surfaces with Vista has been rectified with the SP2 patch so that's a dead end right there. That said there is an interesting article about something called ForceHCResetOnResume. I'll give that a shot and see what happens. @garveyk659: Hibernation works perfectly for me but you might have a point with resume. My system is a Sony Vaio F series and It DOES come with system management software. I've never given it much thought before cos it doesn't at all seem that intrusive. Power Management settings are limited to Low battery Actrion, Thermal Management Strategy (i.e. Priority to heat dissipation or silence, I've selected dissipation) and behavior when lid is shut down. Other then that power plans come from Windows 7. There is no Sony-Specific plan. My current plan is balanced. Still I've got two different possibilities to work on. Lets see what happens.

PROBLEM SOLVED!!! First off, a BIG thank you to all you people who were kind enough to offer me helpful advice. Alex's solution, albeit incomplete, was the closest one to the final correct answer. Here's what worked for me: 1. "Control Panel" 2. "System" 3. "Device Manager" 4. Expand "Universal Serial Bus Controllers" 5. Right-Click each of the listed items individually and select "Properties" for each item. If there is a "Power Management" Tab click on it. Make sure that the "Allow the computer to turn off this device to save power " is unchecked. 6. Click "OK" and "Restart" the computer

Hey Brain, Thanks mate! this worked for me. It was driving me crazy!! 1. "Control Panel" 2. "System" 3. "Device Manager" 4. Expand "Universal Serial Bus Controllers" 5. Right-Click each of the listed items individually and select "Properties" for each item. If there is a "Power Management" Tab click on it.
