Fix USB Connection Problems with yourAndroid Device...

INTRODUCTION

So windows does a really "craptacular" (yes I just made that adjective up...) job ofhandling USB devices. Even Windows 7... as I delightfully found out at around 2 AM lastnight when my computer decided to wig out on me and stop recognizing first my Momo 9Enhanced and THEN my 1.5 Tb WD Elements External Storage drive.

I tried resetting my computer about 5 times, unplugging and plugging things back in, usingdifferent USB ports and deleting all USB devices out of device manager. The last bit...deleting EVERYTHING under USB out of device manager and unplugging ALL USBdevices and resetting the computer DID fix the External Hard Drive. But nothing would fixthe connection to my Android device. I went to bed...

This morning I tackled the problem again and (finally...) found a solution for not just theAndroid device but possibly many of the common Windows USB woes...

USBDeview

A simple program that lets you view ALL USB DRIVERS CURRENTLY INSTALLED.PRESENT AND PAST. I.E. "ghost devices" can be seen and destroyed. It is like devicemanager but 100x better. This is what finally allowed me to straighten out ADB and also

get rid of some other "ghosts" I didn't even know were present in my system.

So, if you are having trouble using PDAnet to install your Android ADB driver... here isYour fix

GUIDE

First some disclaimers...

DISCLAIMER:READ THIS WHOLE ARTICLE ONCE THROUGH BEFORE STARTING!

DISCLAIMER:IT IS A GOOD IDEA TO HAVE at least A PS3 (old school connector)KEYBOARD AROUND IF YOUR COMPUTER SUPPORTS IT AS YOU MAYINADVERTENTLY DISABLE THEM IF THEY ARE USB AND YOU ARE NOT CAREFUL.

DISCLAIMER:DO MAKE SURE YOU HAVE AN ACTIVE INTERNET CONNECTIONBEFORE YOU DO ANY OF THIS.

DISCLAIMER:ALL MEANS ALL! This includes "USB HUBS"... In fact, you should mess

with getting your USB Hubs working LAST OF ALL. In my case, a BAD USB HUB is whatstarted ALL of my problems...

Now on with the guide...

1.If you haven't done so already, download the correct file package from up above.

2.Unzip the contents of the file to a new folder on your desktop

3.Unplug ALL USB DEVICES from your computer except for your keyboard and mouseand shutdown your computer.

4.Leave it shutdown. Now, this might sound a little "out there" but do it anyway :). Unplugyour computer from the wall outlet. If it is a laptop, also take the battery out. Leave it likethis for about 8 minutes. Then start it back up. Another customer submitted this helpful tip.

Apparently getting rid of ALL POWER to the computer can fix USB problems as it canforce a reset.

----------5.Semi-Optional Step (I.E. skip it for now if you want and come back to it if stuff stilldoesn't work) - If you are comfortable with "Device Manager" I recommend you go in andsystematically uninstall ALL entries under "Universal Serial Bus Controller." Work from thebottom up. You will want a mouse and keyboard with the old style connectors on them asthis will stop ALL USB devices from working, including your USB keyboard and mouse.This step is semi-optional as this guide focuses primarily on using USBDeview and I thinkusing just USBDeview can fix most Android ADB driver issues.----------

6.Open up the folder on your desktop where you extracted the downloaded files from upabove.

7.Open up the "STEP 1- USBdeview" folder.

8.Open up USBDeview (no installation is necessary, the program just runs)

9.To uninstall something in this program, you "right click" on the entry and select"Uninstall Selected Devices" You will see a list of stuff. Here is what you want to get rid ofand in what order:

4/12

1. Anything that says "android" or "android phone"2. Anything that says "ADB" or has the word "ADB" in it.3. Anything with the word "Tablet" in it or "Tablet PC"4. Anything with your tablet (or another tablet's) device brand name.

(commonly Teclast is one that shows up a lot, Ployer, Ainol, HTC, etc..)

5. Anything labeled as "USB Storage"6. In the device column, all "mass storage" devices.7. "optionally" IF YOU HAVE A PS3 (the connector, NOT the Sony gaming console...)

Keyboard and Mouse handy you can use them temporarily and also get rid of all"USB Input Devices" and "USB Composite Devices"

You can leave your printers alone unless you are having trouble with them as well. Don'tworry about getting rid of stuff you are using... It will come back when this is all said anddone.

Your should now more or less be "scorched earth" or a "clean slate" is probably a betterdescription.

10.With ALL USB STUFF STILL UNPLUGGED - Reboot your computer.

11.Wait... Let windows take a little time to start up. If you need to plug in a mouse andkeyboard to login you may do so, Once it logs in though, wait while windows does itsthing. This is the point in the game when you really need to have an active internetconnection or if you are using Windows XP you might want to have driver CD's handy forany USB devices you were using that were uninstalled and that need the drivers.

12.Start plugging devices back in one at a time and waiting. DO NOT PLUG IN YOUR

TABLET YET...

13.Once all your external hard drives and whatever else you have are plugged back inand working, THEN move on to installing (or perhaps re-installing PDAnet). DO NOTPLUG IN YOUR ANDROID DEVICE UNTIL IT PROMPTS YOU!

General Fix for USB DriverProblems

I recommend using a wired mouse and keyboard, removing all USB devices and in the section

where it says Uninstall all the faded entries. take that as reading uninstall everything USB, ifyou cannot get hold of a wired mouse then you will have to follow the tutorial as written.

System Settings to go there.
