Problem with USB drivers

Having messed up my USB drivers, doing things that shouldn't be done on Windows I ended up with the following problems:

1. USB Hubs (specifically a Belkin hub first, and all including internal notebook hubs) were not recognized as such, I made them work as USB Root Hubs installing the driver manually, but with problems.
2. Kindle Fire not recognized as a external drive, the was no way I could find a driver for it.
3. Livescribe Echo Pen not being recognized, even installing the driver manually with an error 257, and connecting and disconnecting by itself every 5 to 10 seconds.


Being desperate, I decided to remove all Universal Serial Bus controllers from the "Computer Management" or Device Manager in Windows, using the reasoning, how worse can this be. To my surprise, nothing was now recognized, even when I re-installed the USB Host Controller with the original Chipset drivers from Intel/Lenovo.

Then, something magic happened, I found an article in the Microsoft Support site:

http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/trying-to-install-usb-hubs/e46ebc32-c968-4a24-ad86-8399ae91f95b?auth=1

Basically it suggested updating the driver software from the following location "C:\windows\winsxs" as it turns out, this is very important windows folder, that I wasn't aware of, it is huge, and has every version, of everything that has been installed in your machine. I first updated the drivers for the USB hub, and magically, everything started to fell in place, it took a while, maybe 15 minutes to install the USB hub, but then, everthing started to appear, even the Kindle Fire as an external drive. The only thing missing was the Livescribe Echo, but again, I updated from drivers to c:\windows\winsxs instead of the Echo drivers location (C:\Program Files (x86)\Common Files\Livescribe\PendriverV2.2). You don't even have to look for a directory inside of it, just choose the complete folder. One of the internal USB hubs kept being recognized as a unknown device, but working, I updated it also form the same location.

At the end everything returned to work. Hope this helps if you run in the same of similar problems.

com.pivotmobile.android.metrics file on my Android phone

I recently ran an scan on my phone using MVISION, the scan indicated that com.pivotmobile.android.metrics was sideloaded and that it should be deleted. I could not find any valuable information of its origin on the web, but looking at the application tab on my phone setting, I could find out that it was installed by Claro, my mobile service provider. So I went ahead and deleted, without a problem Take this with a little caution (backup before deleting, bla, bla, bla), but it looks to be a mobile service provider tracking file.

http://localhost/sys/en/classic/login/login page not found installing ProcessMaker

I have been trying to install ProcessMaker using Wamp to avoid having several installations of MySQL, Apache and PHP. After serveral attemps I kept getting errors and could not make it work. My goal was to setup ProcessMaker in the following way. I tried using an alias instead of a Virtual Host. http://localhost/ProcessMaker As it turns out, it cannot be done that way. Whatever you do, you will not make it work (I guess there is a way, but yet have to find one, and would be not supported). The correct way would be something like http://ProcessMaker.localhost This would requiere changes in my hosts file and I guess I will have to go that way. The reference I found was this: http://forum.processmaker.com/viewtopic.php?f=5&t=249 Hopes to save you some time.

Workout pauses while running with Nikeplus on the iphone

This weekend I had my first real run with my Iphone and Nikeplus sensor. Usually I use my iphone only when running in a treadmill, and my ipod nano for running outside, buy since this was a 21K run and had the need for a phone, just in case, I decided to use my iphone. After 6 miles, things got weird, my iphone paused the workout for no apparent reason, so I began receiving the message, pausing workout, sometimes it came back on it´s own, sometimes I had to press play again, with my wet hands to continue. I tried moving it to another pocket to avoid any contact, but, it was locked, so there was no way that I could pause it by contact. The solution As always, easer that you may imagine. I took the earplugs out, and voila, the problem apparently was that there was a false contact in the earplugs, I was using the earplugs included with the ipod, with them, you cand do two things while running, turn the volume up and down, and ..... PAUSE THE WORKOUT so, my advice to you, use conve...
