I received a hotfix from Dell Pro-support that fixed the USB issue on my

Hi, I’m sorry I don’t have a fix, but I am having similar issues with USB and the M3800. I am an IT guy at a small company. We only have three of these systems so far, but I have seen the problem on two of the three systems. When the system boots, sometimes no USB devices work. Rebooting the system has (temporarily) fixed the issue for us every time. I was skeptical when one of our engineers reported this, but I have seen it with my own eyes on both systems. I have not had a chance to do much troubleshooting yet because the users are too busy to give me time with their devices. The systems were started from a powered-off state (not waking up from sleep or resuming from hibernation). Both systems are running the latest BIOS (A03). I have recommended that my company stop purchasing these units until the problem is identified and fixed.
Many thanks for your reply, D1815! I have disabled the USB Selective Suspend in the Advanced Power Options as first step. I'll check in with the end user in a couple days to see if this fixed the issue and report back. I really appreciate people like you who solve their own problem, then take the time to update their post to help other people out. Thank you!
Hello, we are also having issues with the M3800 and it looks to be something to do with the USB hub version or power settings. The PC frequently looses touch screen function and has BSOD after having 143+ Window updates installed. We do not see this issue on PCs that have not had windows updates. Can you list any Win7 SP1 updates that change the USB hub versions or power setting and would cause BSOD upon shut and reboot????? Please help!!
It's been a week since I disabled USB Selective Suspend in the Advanced Power Options and this issue has not reoccurred. We are running Windows 7 64-bit.
Yeah, we are experiencing this issue again, so disabling USB Selective Suspend in the Advanced Power Option did NOT fix the issue for us and I continue to recommend against buying the M3800 until this issue is solved.
