Topic- USB Keyboard - HYSTERIA
Date- 11th Oct-2005
Poster – HYSTERIA -

Hi – I see you are using a cordless USB Mouse – How about the Keyboard – Is it a Logitech Mouse & Keyboard Set – Are they wireless using network card or what – maybe needs calibrated (??)

Usually these things happen when you receive a {Windows Update] - & - automatically download & install – Do you recall any recently [Windows Updates] – like just before your problem -

I can give you a little tool that can help you when using [DEVICE MANAGER] – It will let you view all the [Non Present Devices] – Which can aid you immensely when tracking down USB Issues – It is a (2 Step) process that only needs to be done (1 time) –( Step – 1) - Set [Folder Options] to [Show Hidden Files & Folders] – (Step – 2) - Set [Device Manager] to [Show Non Present Devices]
______________________________________________________________

Step – 1 Open [Control Panel] and set [Folder Options] to show [Hidden Files & Folders] – (1 time process)

(1) – Click [Start] Button
(2) – Scroll up to [SETTINGS] > Click on [CONTROL PANEL]
(3) – Open [Folder Options]
(4) – Click on [VIEW] Tab
(5) – Scroll down to [Hidden Files & Folders]
(6) – Click the [SHOW HIDDEN FILES & FOLDER] Option
(7) – Deselect OPTION – [Hide Protected OS Files – Recommended]
(8) – Click [OK]
(9) – Close [Control Panel]
_________________________________________________________________

Step – 2 Prep [DEVICE MANAGER] to view [Non Present Devices] –( 1 time process)

(1) – Right Click [MY COMPUTER] > Click [PROPERTIES] on Drop Down Menu –
(2) – Click [ADVANCED] Tab – (on System Properties)
(3) – Click [ENVIRONMENT VARIABLES] Tab -
(4) – Under [SYSTEM VARIABLES] Section – Click [NEW] Tab –
(5) – In [NAME] Section – Type – devmgr_show_nonpresent_devices
(6) – In [VALUE] Section – Type the number 1
(7) – Close out by Clicking [OK] Tabs – 3 Times – (3 levels/panels to close)
(8) – Click on [START] Button > Then click on [RUN] –
(9) – Type – devmgmt.msc – and then Click [OK] – This will open [DEVICE MANAGER]
(10)– Click [VIEW] on Menu > Click [Show Hidden Devices] on Pop Down Menu –
(11) – View [Hidden Devices] – Indicated by Faded Gray Print – (Close when completed) – (Now [Device Manager] is now set to view [Non Present Devices] – (NOTE) – You MUST set the [View Option] – [To Show Hidden Devices] – EACH time after opening [Device Manager]
(12) – Restart Computer – (To ensure a good [Initial] beginning -
_________________________________________________________________

Now Open [Device Manager] in Normal manner & Set [VIEW] options to [SHOW HIDDEN DEVICES]

Standard Process to Open [DEVICE MANAGER] with [Show Hidden Devices] Option set -

(1) – Right Click [MY COMPUTER]
(2) – Browse down [Menu] to [Properties] > Double Click to Open Properties Page
(3) – Click on [HARDWARE] Tab
(4) – Click on [Device Manager] Tab
(5) – Click on [View} on Menu Bar
(6) – **Click on [Show Hidden Files]**
(7) – Expand Folders as reqyired
(8) – You need to double left click or right click each line to reveal additional info
(9) – [Non Present Devices] will be denoted by –(Light/faded gray print)

** Step 6 will have to be set to [Show Hidden Files] on each opening of [Device Manager] **
___________________________________________________________________

Now Browse thru – you need to Expand Folders & either Left Double Click or Right Click all lines to see more info – you are now looking for the – [Muted/faded gray] Devices and any Yellow Warning Signs or have a Bold repeated instance of same name –

If you do have a faded gray instance & bold instance – That is indicating that either 2 Drivers are installed or you have some remains of a previous Driver –

Now you will see a lot of Non Present Devices – That is ok – you just don’t want to see many with the same name – These [Non Present Devices] (The Proper Ones) are kind of a place Holder for PnP when the Device is either [TURNED OFF] or [DISCONNECTED] – so that whenever – they are turned ON or CONNECTED – PnP will NOT try to reinstall – The devices will simply play/function as usual – [EXAMPLE] – You do not always Turn Printer ON – but when you do – you just want it to print – Not to be reinstalled each time – So when you do Turn the Device off – You will see the transformation of [Device Present] to [Non Present] – change from Bold to Faded gray –

This is more evident with USB Devices than with non USB – USB Devices are PnP Compliant –

Anyway see if this brings out any clues as to what is happening – with USB – If nothing else you will be able to see some USB Problems/Issues by using [Device Manager] set to [Show Non Present Devices] – Just remember to set [VIEW OPTIONS] to [See Hidden Devices]

__________________________________________________________________

Now – Look for your Keyboard [Non Present USB Device] Instance - (Faded Gray) – Double Click - & try to reinstall Driver – If you are lucky – It will be the Keyboard [Instance] that had last working Driver before the [UPDATE] –

Sometimes just by connecting to a different USB Port – PnP will [FIND New Device] – I see by [Device Manager] your USB Chipset is SiS – Just a note – SiS Host Controller Interface is noted to have some of these [Strange USB Issues] – No big problem – just requires some work around ideas –

And sometimes just cleaning up these [Non Present Devices] Instances – Your USB problem goes away –
I am not sure why – but sometimes these [Non Present Devices] block/confuse PnP from finding the proper Driver –

It is just a matter of finding the [Correct Sequence] – Every time you uninstall a USB device & reinstall – you can create another Instance of a Non Present Device – So at least with this [TOOL] – You can see what is happening – Also you can now see some of the [Unknown Devices] & [Not working Devices] that you never were able to see before – You can now – at least clean up this mess -

I just cannot give you a [Direct Repair Procedure] that will work each & every time – Now another problem with USB –

Did you just recently add a [New USB Device] such as a Camera or WebCam or USB Drive – sometimes with these Controllers – (Ali – SiS –VIA) Chipsets – The earlier Installed devices – cease to function – And by cleaning up these Non Present Devices & doing a Reinstall helps –(??)

I haven’t put it all together – yet – but I am working on it -

Hey Jack,

Thank you for your help. I followed what you had said, and it did help me recognize a few things.
However, my keyboard was another issue. I just bought a new one, and it works fine now (Another Logitech - I think the software was just needed). I really appreciate your help. I do have one question though: I now have all of those hidden and temp. files all over my computer and my desktop, and I would like to have them hidden, is there a way to reverse what you told me so that I won't see those? They just cause clutter which I don't need. It did help me at the time, though.

Thanks!
Dan

Thank you for your help! I did have faith in you, however, my parents had wanted an excuse to get a new keyboard anyways. So it's no big deal. I'm sure you could've helped me to figure it out on my own.

Thanks Jack!
