I'm very new to Android development (my first app), so please bear with me.
I'm using Eclipse with the android SDK. Using the Android SDK and AVD Manager, I've installed the Usb Driver package, rev 3.
To this point, I've been using the emulators to debug and develop. Now I need to debug on my device (bought a ViewSonic GTablet). Somewhere in my searching for solutions to how to get this going, I found that I need to get the drivers correctly installed. Those instructions directed me to:
- Modify the android_winusb.inf file in the usb_driver folder
- Install USBDeview program
- Removed all drivers associated with Andriod and NVIDIA Tegra 2 (I think there were 3 or 4)
- Connect the GTablet with USB and follow new found hardware wizard. Direct it to modified .inf file
The problem is, the "Found New Hardware Wizard" does its thing automatically without user intervention. I end up with 1 NVIDIA Tegra 2 USB Device driver. I think I'm supposed to have another driver called something like "Android Composite ADB Interface".
I tried using the Add Hardware wizard to install this, but it always results in saying "This device cannot start. (Code 10)".
Sorry for this lengthy explanation...can anyone please help?
Hi,
I struggled getting adb working until today. There's info for getting adb working with Gtab here:
http://forum.xda-developers.com/showthread.php?t=827209
The key for me was adding the 3 lines to the .inf. Make sure you have USB debugging enabled on the tab.
Then, in Win Device Manager uninstall the devices under Android.
Then unplug the USB, then reboot Windows.
After Windows starts, plug in USB, then when wizard pops up, browse to the USB driver dir.
Jim
Thank you jimcpl for the reply.
It's still a no-go.
I have done all the steps lined out in the link you provided--and thought your reboot step may be the key to making it work, but that didn't do it.
When I plug the GTab back in, I do get a "found new hardware" popup message, but no wizard is appearing. The result is, the system is installing:
(With the help of USBDeview window)
Device Name: NVIDIA Harmony
Description: NVIDIA Tegra 2 USB Device
Device Type: Mass Storage --> This one I can use to transfer files
...
I see no other devices associated with the GTab
What device type should the "Android Composite ADB Interface" be?
Also...Maybe this is a silly question, but isn't it the miniUSB connection I should be plugging in to?
More info on the problem
I found that when attempting to install the adb driver, the system is not using the .inf file I'm pointing it to. It is using one titled "oem24.inf". I found this by looking in Start->All programs->Accessories->System Tools->System Information. Then under Software Environment/Signed Drivers there is the "Android ADB Interface" listed.
I can see the referenced oem24.inf file (and associated .pnf files) under C:\Window\inf folder
BTW. I'm on Windows XP Pro SP3
In here I see at least 3 .ini files that have the three lines that we're using to modify the android_windusb.inf file with.
So the question now becomes...
How do I get the installation (or driver update) to use the .inf file I point it to?
Another recent thread suggested that window's supplied drivers will have to be removed. Are these what he may be referring to? If so how do I do that?
PLEASE -- I need a response from someone that knows something about this!
Memory doesn’t serve me too well in windows xp but go to device manager, click on action, add legacy hardware, Install the hardware that I manually select or something close to that then, have disk and point to the directory where the inf is located and install it. Make sure you modded the inf from the post above and you should be good to go.
Thanks...but, not the solution
I really appreciate the suggestion littleoldme!
In XP, Device Manager/Action menu only has the "Help" link which lauches the Microsoft Management Console. Doing a search for "Legacy" in the console results in no hits.
So I'm still stuck

I found your answer.. see URL below
tegradeveloper.nvidia.com/tegra/forum/after-installing-froyo-adb-cant-see-device
I want to thank all who responded with suggestions to this problem.
I've followed all advice given and carefully followed all directions given in suggested links.
Unfortunately, there seems to be some underlying condition on my pc that is preventing the successful installation of the necessary adb driver. No matter what I have done so far, Windows is choosing NOT to use the driver I point it to, and use what it wants instead. I don't even get the "New Hardware" wizard when following the directions. It installs automatically and I have to launch a separate "Install new Hardware" dialog.
Anyway...through persistence, I've been able so far to develop this first app without the debug connection to the device using the development emulators, then installing the signed .apk on the device for further testing (via the one USB mass storage connection I do get).
So, maybe one day I'll find the reason, but for now I'll be purging on to get the app ready to go.
Thanks again for all help received.
I just come across this thread. After insert the usb device, then you might might find the unknown device in device manager. unstall that unknown device. And then do a hardware scan again in device manager. After it find your device again, point back to your USB inf file. It might work this way.
One thing I forgot. Do not unplug your device between uninstall and hardware scanning.
AAAHHH! GTAB Eclipse ADB frustration!
Thanks for all the tips, everyone, but I've been trying for days to be able to connect my gtab to use as a device for installing/debugging my apps. I too am running Eclipse using the emulators to date.
I've tried the steps outlined in the link provided by jimcpl, as well as others that are slightly varied, but to no avail.
I am running Vista SP2. My Gtab has been rooted, running ClockworkMod, and TnTLite 2.2. I also updated the Google USB package, rev 4 via the SDK/AVD Manager after attempting to use the rev 3 usb package.
Should any of these be reason why I cannot connect my gtab to Eclipse via ADB?
I'm totally frustrated...If anyone has any other suggestions, please forward them on!
Thanks in advance.

On the Gtab, is USB debugging enabled?
On the Windows machine, did you add the 3 lines for tetra?

Thanks Jim...Yes, and yes. I finally got connected. Old drivers were conflicting, and even though I'd repeatedly uninstall them in Device Manager, the ADB USB drivers would load, but not start the device. I finally got USBDeview to uninstall them successfully after many attempts and reboots, plugged in my GTab, and finally installed correctly, and it works like a champ!

Hi,
Ok, thanks. I'm glad it's working for you now.
FYI, I think that when you "uninstall" a device from Device Manager in Windows, it doesn't physically delete driver files, etc. from your hard drive. It just removes the references to the removed device drivers from the Windows configuration.
That's why if you reboot, or do a scan for devices again, and if Windows thinks that it detects the physical device, it'll try to use the same driver files, .inf, etc. In that case, you have to force the installation of the new/correct driver, by not letting Windows automatically find the drivers (because otherwise, Windows will find the same ones from before, the non-working ones).
It's kind of a pain sometimes ... I ran into the same thing when I tried to install the ADB USB drivers. I downloaded the USB driver files from Android dev website, but those are generic. They have stuff in the .inf for some phones/devices that Google has relationships with, but not the "proprietary" ones like for the Gtab. That's why you have to add the 3 lines, which match (I guess) the Gtab.
Jim
I'm not new to installing hacks, all of my devices are hacked including PS3,Xbox, and iPad. But I got a Nextbook for my gf for Christmas, found a rom on these forums, and can't get past the first step. Im supposed to put 2 zips on the sd card root which I did, the leave the RX folder with all the drivers on my PC, which I did. Next I have to hold down the volume buttons while hooking up the tablet to the usb, then search for the drivers. This is the problem. On one computer it showed up as M3 Chip in device manager, and couldnt find the drivers no matter which folder I directed the browser to. On the other computer it showed up as unknown device (which is the way it was in the instructions) buts still wouldntfind the drivers. any help would be greatly appreciated. If you tell me what to do I will understand, thanks.
I need to root this device to upgrade the software, but I can't find the ADB driver, so I can't do anything about it.
I've tried all the usual suspects, SuperOneClicks driver doesn't work, neither does the robodobo thingy. Nurvo doesn't have any drivers on their site.
The device self-identifies as rk30sdk, which is pretty normal for the 3066 chipset, I guess.
Anyway, does anyone know of a driver that THEY KNOW will work? If you've done it yourself, that would be great, but please don't just link me to a forum post or name a driver that they think might work. I've already installed five different drivers, I'm getting tired of it..
have you checked if your device have usb debugging checked on and if you can access linux do lsusb and find the device id then go back to windoze and edit an adb usb driver inf file copy one line from the other line then change the device id in it to match your device it did worked for me on old tablets

I don't have Linux, and I understood almost nothing of that...
Under windows you can install almost any android driver regardless of your device, at least i use the same pack for motorola/lg/samsung phones and also some tablets work fine, just needed a different driver for a a13 tablet, but also used a generic driver it was not device specific.
I need help figuring out how to root a RCA RCT6077W22 tablet. It has Android Jellybean 4.1.1- v1.0.1, 8GB built in storage, 1GHZ processor, Google apps installed, kernel is [email protected]#132.I'd like to try to root it from the tablet itself if not I'm familiar with SuperOneClick as I've used it for my Samsung Galaxy S 4G before I should it. If it comes to that option I need to be able to use a rooting program on my computer that does not require internet the only internet I am able to use is the libraries. I have a laptop but no charger so my laptop is dead. I'm not a noon when it comes to rooting as I've mentioned I've done it before. Just need help finding a root for this tablet. I appreciate any help I get and thank you. If you need more info feel free to ask. I've also looked at the topic about the 4GB but its not that helpful is why I created my own topic.

I have the rct6378w2 RCA 7' 8GB tablet (4.2.2 JB). (Black Friday 2013 Walmart for $49)
I was able to root it by first installing the pdanet drivers (for adb access). And then using the kingo app, which you can get from http://www.kingoapp.com/.
Its free but closed source. I found it via this youtube video. https://www.youtube.com/watch?v=8MiZtZCqu4k
Worked even with the 1.0.2 update installed (which I have no clue what it did (17MB).

I cannot get pdanet to get the drivers. I cant find any drivers anywhere. Pdanet says to click ok after connecting, and it just says no android device found..I think there's an error box too.. I don't know how to fix it. I also have the tablet from the black friday event. Exact same one. Also, I have USB debugging on...
UPDATE: I found out the problem! The support files weren't in the root file I had the .exe in. I just moved the .exe to the same folder with the support files, and now I'm rooted and ready! Thanks!

how are you turning on usb debugging? I also have this tablet(purchased on black Friday from Walmart like everyone else) and mine doesn't seem to have that option anywhere. in fact, compared to the previous two android products I have, this device seems to lack ALOT of available functions. though I am capable of navigating a recovery menu at boot. but that doesn't do me any good for using pdanet. that seems to be my biggest road block. pdanet wont install because the onl;y way I can allow my device to connect to my pc with adp is using the adp updater in the recovery boot menu.

It is a hidden option that needs to be enabled. Follow this guide: www ninjaromeo com / enable-usb-debugging-developer-options-jelly-bean/
I just enabled this option on my Walmart BF 7" RCA RCT6378W2 tablet.
Sorry I had to mangle the link because XDA wont let me link external sources yet.
Glad I could help a few. Now, someone get on a functional recovery ;p
I have poked around a little at the stock recovery, backing it up, etc.. But am not brave enough to try and get CWM working on it.
I was able to use th Xposed framework for a few mod's no problem. Battery mod, reboot menu, hide navbar, etc.. But Xposed can only do so much.
Edit: I heard on reddit this tool also works for rooting. I have not tested it (already rooted with the other method).

I was not drunk when I made this post...I have the RCT6378W2 if you go to about tablet in your settings and repeatedly tap the build number...the deveolper options will appear...I fell out of my seat when i discovered this.
On a side note...if you repeatedly tap the android version...a cute picture of the android jellybean will appear. Try it.

1: Install drivers. Seeing as RCA does not provide drivers, we had to find some that work. That's where PDANET comes in. Their drivers support a very wide range of Android devices. We are not installing it to tether. We just want the drivers it provides. So download PDANET, install, let it detect your device, install the drivers, and then afterwords you can uninstall it.
2: Enable Developer Options. Settings>About tablet> Tap Build Number a bunch of times till it's enabled.
3: Enable USB Debugging. Options>Developer Options>Click On (up top)>Then checkmark USB Debugging
That should clear up some of the confusion in this thread. How you root after step 3 is up to you. Personally, I did it with Kango. Which was straight forward. Connect device, hit a button, Say yes to a couple questions, reboot, presto done.

Thanks, that sorted things out.
To make clear, and aid in any other inquiries, I managed to find an ADP connection mode, among other android update features. with the device off, hold volume up while turning the device on. it should boot to an image of an android with an open chest panel and the words, "no command". if you push volume up again it will provide you with options and instructions on how to execute. you can manual update the device with an SDK through USB ADP mode this way. I'm not sure if that makes anything simpler or generates a work around but I hope it helps with future development for this device.
Well got root now we need a recovery...
For some reason when trying to make sure I can send adb commands to my tablet, I am showing no devices connected. I check in device manager and it shows up as Android ADB interface for the tablet. These drivers were installed with the latest version of PDANet. Thoughts or how were you all able to get the drivers fully loaded and working? I have developer options already enabled and USB debugging mode is checked.

You need to create "adb_usb.ini" in "Users>Username>.android".
Inside "adb_usb.ini" insert "0x2207" and save.

I had this problem too. make sure you're using the most recent version of pdanet. for whatever reason the older version just hang there and dont work right.
Installed the latest pdanet. It wont install the driver. I checked the device manager and it still shows the device without the driver. not sure what else to try..
theres a thread that explains how to root TVpad2 OS but also installing android but unfortunately Im still confused to where to begin...
Since I can't post outside links, I'll post the replies here:
this seems to indicate tvpad has onboard storage of ~4G which runs the applications, though i'm not sure about the function of each partiton. it doesn't seem to be easy to put a custom os such as 'openelec' into the storage through telnet. i think in order to do that, one needs to tether the box with linux machine first...
here's the guide that i'm trying to follow:
REMOVED
^You are correct. Not going to be easy. At least I had many sleepless nights trying to find a way to put Android on TVPad1/2/3. Probably not going to help you with your Openelec project, but for Android I found an interesting article which is mostly related to TVPad2/3 (tcc8925 chipset): REMOVED . Never got much further with it since I never figured out how to put the TVPad2 into FWDN mode (bricked a perfectly working unit trying to figure that out). So I called it quits. I am a Windows guy though, so maybe for some Linux wizard it's a piece of cake.
^thanks for the info, it's good to know.
now i realized that putting 'openelec' won't be possible because onboard rom would require the firmware be loaded first since it contains drivers specific to the tvpad. however, it's unclear to me how one tethers tvpad2 to computer for editing and transferring firmware, since tvpad2 only has one standard usb port( a host usb?). and the linked guide utilizes a miniUSB to usb cable to link the CX-01 mini PC to computer for updating the firmware. anyway, these procedures seem too complicated to go through for what tvpad is worth.
this is a link i found that contains some info on flash fwdn image with pc to devices with TCC8902/TCC8803 chipset:
REMOVED
Could anyone give me some insight? Thanks
