M3800 USB problems

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.

Hi, also an IT person.  I am having the exact same issues with the USB or I get a BSD when I shut down the box.  Messed with USB settings and that helped some.  Called Dell, they replaced the memory.  That made it worse.  Tomorrow they are going to replace the mother board.  We will see what that does.

Hi have Dell precision 3800 for 2 weeks - very fast but intermittent USB problem, shut down  and mouse problem then the whole system goes down - tried 4 fixes from dell and our own IT support solutions and still the same problem is occurring intermittently , thought it was software problem but does not look like it from what we have seen  - so sorry to say beautiful machine but i am busy cardiologist and cannot survive without a dependable laptop and i have told my IT people to give up and  i am sending back the machine - so disappointed it did not work correctly as when if did work it was fantastic -good luck to you others and i hope Dell solves it for you

Yes I am having the exact same issue myself. Can you please update as soon as you figure out if the motherboard is the issue. I have pin-pointed it to the powered usb controller as the cause of the problem. I just can't figure out how to fix it.

Please let us know if this is the fix- seems strange so many of these have been sold and not more complaints -
