Windows 7: USB Devices not seen in Windows 7

Probably best to uninstall what's there, reboot, and use the downloaded HP pkg to install the device.
As I stated previously, HP does NOT have drivers for this printer with respect to Windows 7 x64. They do have XP drivers for download, which I have, but will not install as expected. For the time being, I have swapped both my mother and fathers printers out, as the HP PSC 1200 works with my father's XP system.
And the newer Canon works with my mother Windows Win 7 x64 computer.....but it does not seem to scan or print as good as the HP. My mother prints cards and pictures, my father.......taxes!

I did uninstall the drivers that were automatically installed by Windows 7, restarted, and then let Windows 7 try a second time to no avail.

My main concern for the time being is the USB anomalies. upon installation Windows 7 did not recognize the keyboard, a older Logitech...and only worked if I used an adapter to the old style keyboard/mouse cable (PS/2) Ports.

I plan to have my mother perform the procedure stated below:

Try this: SFC /SCANNOW Command - System File Checker

It may be a slow process being a 3hr drive from the computer I wish to fix, so bear with me and I will add aditional info as I perform some tasks from afar!!

I should know better.... but I kept seeing Win7 on the HP page - when I drilled down it clearly says what you've been trying to get trhough my thick skull. HP punts and only provides an OS driver. Please accept my apologies.

There is a Device Manager trick to try. Mom will need to add a new environment variable to her user profile.
USB Devices not seen in Windows 7-devmgr.png

Variable name: devmgr_show_nonpresent_devices
Variable value: 1


Once this is set, devmgr shows devices that have been removed if you click on View -> show hidden devices.

You can safely remove any ghosted (grey) USB entries, the will be reinstalled the next time the device is attached.

Very Interesting trick!

An additional piece of info with regard to the printer issue.
I use a software utility called "Driver Magician" to display devices and drivers and to possible locate a driver for the HP printer. And although Device Mgr showed the HP driver, the Driver Magician software did not detect the presence, though it found most all other devices!

Now, since the printers have been swapped out...mother to father, it may be difficult to perform these tricks unless I get then to swap back the printers. I may have to wait.

With respect to the USB HDD. I have had issues as such before where the Drive did not showup in Windows Explorer, but they did show up in Administrative tools - Computer Management - Disk Management. It is possible that the device was unplugged from the USB without using "Safe USB" removal techniques....thus a chk disk command might possible find and fix this...

Anything is possible..... If you can't see it in Windows Explorer, the only way you could chkdsk it would be in Disk Management - IF you can see it there.

Something easy to try: boot into safe mode and see if the USB devices behave.

True....
I think I can walk my mother through this procedure...at least to see if the drive is visible in disk management. Not sure what file system is on the 2.5" USB HD FAT32 or NTFS. I'm hoping I was smart enough to make it NTFS.

I can also get her through the safe mode check. I created a multi-boot option on startup for her to go directly to safe mode.


...FOR FUTURE REFERENCE...
Command Prompt Method to chkdsk x:

Alternatively, you can use the command prompt to perform a scan on a drive letter of your choice by running "chkdsk x:" where x is your drive letter. The manual scan options are:

  • /F Fixes errors on the disk.
  • /V On FAT/FAT32: Displays the full path and name of every file on the disk. On NTFS: Displays cleanup messages if any.
  • /R Locates bad sectors and recovers readable information (implies /F).
  • /L:size NTFS only: Changes the log file size to the specified number of kilobytes. If size is not specified, displays current size.
  • /X Forces the volume to dismount first if necessary. All opened handles to the volume would then be invalid (implies /F).
  • /I NTFS only: Performs a less vigorous check of index entries.
  • /C NTFS only: Skips checking of cycles within the folder structure.
  • /B NTFS only: Re-evaluates bad clusters on the volume (implies /R)
"CHKDSK x: /F /R" would perform a full scan (including bad sectors) and attempt to fix them.

I've never used this, but other members have
TeamViewer - Free Remote Control, Remote Access & Online Meetings

This might alleviate a trip to mom's and help provide current feedback to the forum.

Team Viewer...
I've used microsoft's remote access back in the day, till it went bonkers, then Symantec's PCAnywhere. There was one other program too, but can't remember it of the top of my head. I seem to run into trouble with getting through routers or modems, though I don't think I have them secured as yet.

I will read about Team Viewer with WinXP > Win7 or Win7 > Win7.

There is a WARNING posted when running "sfc /scannow,"

warning Warning
Be aware that if you have modified your system files as in theming explorer/system files, running sfc /scannow will revert the system files such as explorer.exe back to it's default state. Make the appropriate backups of your system files that you have modified for theming if you wish to save them before running sfc /scannow.


I did customize the Windows explorer "folder properties" ...to display large icons, show file extensions, show system files.... I also set the logon background to a custom image and altered theme colors via Win 7 interface. I did NOT replace system files so that one could use third party themes. Are these changes going to be returned to default values??

SFC will replace any SYSTEM file that doesn't match the Win7 cache reference. It should not affect any user customization or data.

Run SFC /Verifyonly to see what might be affected - no changes are made.

TeamViewer runs great on both XP and Win 7, even without installation. Amazing. Always had troubles with so many other programs such as these.

I will put my mother to work tomorrow as my phone was out today.

Ha! Right! Now What!

My mother called this morning. She was using her computer and placed it in sleep mode while she went to have breakfast. When she returned she could not return from sleep mode. After reboots..etc. nothing was displayed on the monitor and her optical mouse was not lighting up.

I had them unplug the computer, check cables, and retry. Nothing.... nothing on the screen, no mouse light.

After checking that the monitor does indeed still work (connected to another computer) I am suspecting the motherboard.

I should have some bios visibility on the screen regardless of peripherals such as mouse, keyboard, HDD... right?? ...the ability to boot to the bios...yes?

Ahh computers....and the life of leisure! So much time saved!

...or, perhaps the installed graphics card as the mobo does not have an on-board graphics connector.
