Hello All,

 

          I am not sure whether this is a Windows Issue or not, it could be driver related, but I am leaning against that.

 

          I have just purchased two laptops that are the same in every respect except the color of their cases.  Here is the Speccy system snapshot.

 

          I am having a peculiar problem with the SD card reader and the USB 2.0 ports:  if the computer sleeps (at least for any period of time) these devices "vanish" from Device Manager.  If I open Device Manager and hit the "Scan for hardware changes" button they always come back upon completion of the scan.  I think the same is happening for Bluetooth as well, but I haven't needed to use it enough yet to be certain of that.  It seems to me that the Bluetooth device icon shows up again during the hardware scan, but I'm not 100% positive.

 

           I seem to recall, in multiple versions of Windows, that certain devices can go through this "vanishing act" either secondary to sleep settings or power settings, but not at the "top level" for either.

 

           If any of this seems familiar to anyone, would you kindly point me to the system settings I need to change to rid myself of this vanishing act?

Is it a sleep setting in the BIOS? or, in the manual sleep settings there is a USB setting buried in there. I can't look it up as I'm in a motel room on my phone but I'm sure you know what I mean.

I take that last part back...😀

xrobwx,

 

        Thanks for the pointer.

 

        This was one of the things I had been remembering as well as tweaks you can make in Device Manager in the Properties dialog:

 

Attached File  USB_Hub_Properties_Dialog_Dev_Mgr.jpg   31.3KB   0 downloads

 

 

I'll bet tweaking at either location changes the same registry key (or at least some of the same ones, since the Device Manager Properties don't differentiate between on battery power versus plugged in).

Hi Brian,

 

"I'll bet tweaking at either location changes the same registry key (or at least some of the same ones, since the Device Manager Properties don't differentiate between on battery power versus plugged in)."

 

The USB selective suspend is controlled through:-

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings

 

Whereas Device manager devices are found in:-

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\

 

Not all devices have a plug n' play option USB being one of them.

 

Power plan advanced settings gives you the option to enable or disable suspend on both battery and power, it will do no harm to disable this, however I do not think this is the cause, I would first try an update of the chipset drivers.

jenae,

 

         I've already looked at the HP website and there do not appear to be any updates other than for the Realtek Card Reader, which I do intend to download and apply.  My internet service slowed to an absolute crawl last night but appears to be back to the land of the living this morning.
