USB 3.0 hub disappearing after resuming standby

I am experiencing problems with my USB 3.0 ports on a Delock 89359 PCI-e x4 card which is a combined SATA 6Gb 2 port and 2 external USB 3.0 ports card which I have installed to a PCI-e x16 v2 slot.

The problem is that when I put my system into standby, after resuming from sleep, the two hubs USB 2.0 and USB 3.0 disappear which means the ports do not function. The only two devices left installed after resuming are Etron USB 3.0 Extensible Host Controller and Etron USB 3.0 Extensible Root Hub but there should be two additional hubs which makes any devices accessible. I will update after a reboot with their exact names but one is a USB 2.0 and the other is a USB 3.0 hub.

I use a USB 3.0 Startech dual docking bay SDOCK2U33HFW which I use to plug in a number of drives as needed. However after standby when the USB hubs disappear, the drives cannot be accessed until a reboot which is proving very annoying.

I have tried scan for hardware changes in device manager without success. I have tried uninstalling the Etron application drivers and unplugging the docking station and reinstalling the drivers, which only installs the two devices that I listed above and not the two hubs. I have also tried v1.0.0.118 and v1.0.0.119 Etron drivers with no improvement.

This windows 7 x64 SP1 install is newly done less than 2 weeks ago and the majority of windows updates have been installed which in itself was a challenge with updates not downloading, not installing and spending hours checking. I did finally solve this but I guess that the updates are what might be causing these USB problems but that is only a wild guess.

Therefore I would appreciate some help to stop the devices disappearing after resuming from standby.

BTW the PC system is marked [2] in my system specs

The two hubs are Etron USB3 (SS) Hub and Etron USB2 (HS) Hub.

Does anyone have any ideas on how to solve this and prevent the hubs disappearing when using standby?

could also depend on your power settings for USB and PCI.

It's not such a little problem when it prevents my PC being used effectively. I do not want to have to keep rebooting just to restore a device because it should not be necessary.

Something must be causing the devices to vanish and I would like to rectify the problem and it's cause. I use standby a considerable amount, putting my system asleep when I am working on something but need to do other things and I go back to it when I have time. It is very inconvenient if I have to close everything and reboot all the time.

USB setting is set to selective suspend: disabled, whereas PCI-e Link state power management is set to off. I don't think that either of those should adversely affect USB devices.

Well the obvious thing to try of course is alternate settings for these, and another place to look is BIOS. Make a careful note of where you start of course and then try ever other combo of settings--I've been there and done that and you can end-up confusing yourself.



It does sound like a driver incompatibility, but if you've tried all the mfr drivers for your hardware and need to t-shoot some more you might go to Uwe Sieber's Homepage and look at his Drive Tools link. I've used DriveCleanup to fix odd problems and UsbTreeView to ID how my devices connect & run.
