Need help on developing USB attached device - Android Q&A, Help & Troubleshooting

I have a problem. I have a Tab Pro 12.2 WIfi only tablet that the Wifi does not work on. So I have found I have two options: one replace the original wifi hardware and antenna or two get the tablet to work with a usb wifi antenna. I am trying option two but ran into a wall. I cannot find any USB Wifi antennas that work with Android. I have one and talked to the manufacturer and they dont have any plans to develop that capability. I am not a very good programmer and need advice on how to go about getting my tablet to recognize and use a USB wifi antenna instead of the stock hardware.
As far as versions of Android, I have ROMs for Lollipop, Marshmallow and Nougat.
Thank you in advance

How Can I Use 3G USB Modem with Tablet s?

is there any one know?
I have huawei E170 3G modem and disable flashdrive mod. I disabled with DC-Unlocker client
But Tablet S did not recognize the 3g modem (Unsupported USB Device Connect)
Please Developer Friends Help me.
Thank You

Here you've got some info. Unfortunately you will have to wait for a root solution.
yes I tried some posts but nothing else
Yes we are waiting developers friends
Tried it using an aircard but android only picks up the usb stick.
I dont know if it actually help but I saw this on tech republic when they open the tablet.
3G-ready motherboard and case: Sony left an open spot on the motherboard and inside the case for a 3G or 4G card. The internal mounting bracket even has screw holes for it.
Dont know if it is possible to add an internal modem or install driver for that.

At least worked for me. It disables other functions of USB 3G sticks and leave them to be acting only as 3G modem, which then tablet recognizes.
Is there anything new? I have got rooted ICS on my tablet. Is it possible to use 3G USB Modem on my tablet? I have got 2 USB-Modems. The first is ZTE K3565-Z and the second is Option 4G Systems XS Stick P14. Is there a solution?

If darkjesus's method didn't work, then I'm not sure anything will. These modems are not easy to work on a lighter system like Android.
I'm happy to be proven wrong, of course.
In a german forum, i found an app called "UMTS Manager". With this app you can connect with 3G Networks with some Huawei-Sticks and maybe some other devices, too. They use mode-switch to switch device mode to modem only and then it works for them. Here's the link:
http://www.android-hilfe.de/asus-ee...-stick-zum-laufen-kriegen-17.html#post3236187
Of course, a lot of pages But some of them got ZTE K3565-Z working. For me it doensn't. Maybe we can find a solution
I found the reason, why it does not work on Tablet S. Our Tablet does not create ttyUSB*-devices when attaching 3G Modem to the Tablet. Normally it creates ttyUSB*-devices, attaches the Modem there and you are able to connect. I think it's a kernel issue or Sony modified the kernel. But with Custom Rom and Kernel which has got this "feature" it is possible to connect via 3G Modem. Maybe one of us could create this custom Rom..
So how?
Hi there friends
So any tablet s user here found a way to use 3G on this tablet?

You will have better success looking for a portable 3G-to-WiFi hotspot device. Not only will you not have to worry about installing USB modem drivers, the device will work with a non-rooted tablet. Also, if you have a 3G smart phone, look into WiFi tethering.

ICS - 3g dongle support

Wondering if anyone here has been able to use a 3g dongle using otg cable and y-cable? Does ICS have any drivers built in?
Thanks
Bump anyone?
What is an otg cable and y cable?
Otg. Cable is basically micro USB to USB cable and y cable is required in order to provide power to the device you'really using.
I'm pretty good at figuring out bad lingo but I'm not quite sure what you're trying to accomplish. Are you trying to get 3g on your touch pad or power the 3g dongle like a hotspot? I'm assuming the micro USB to USB plugs into the touchpad and part of the USB "Y" cable and the dongle into another part of the "Y" but what does the y cable plug into? Being detailed and descriptive goes a long way to getting answers on the interwebs.

Figured the people that would know if it works/how to get it to work would already know what the cables are seeing as its the same equipment required to hookup any USB device, be it a keyboard, USB flash drive or external hdd to the touchpad.
Basically I want to use the 3g dongle to get internet on the TP. To do this would require external power to the dongle as the TP doesn't have a powered USB host. Most likely require drivers as well.
wouldnt tethering to a cell phone that already has a nice data plan be much better than a franken-dongle setup?

At least in the US, tablet device plans tend to be cheaper than tethering plans and carriers are starting to crack down on such practices. Its a valid request.
Not really sure if its possible on the touchpad, but I know some other devices are capable of it like the Archos G9 series and some Chinese tablets so I would not be surprised if it were.

I think most US carriers would be unhappy if you used a 3G USB Modem with a tablet plan since the modem could be used with a laptop too. Pretty sure it would be against ToS to do so.
In any case, if that's the route someone wants to go, then wouldn't some sort of 3G Wifi hotspot still be better than a "franken-dongle"?

Good point on both accounts. A mifi type device would probably be the way to go, less cables, more universal usage, etc. Only downsides being that its pricier than a 3G dongle and the battery life would not be as good, but it would be guaranteed to work.

Yeah, i tether via wifi to my android phone all the time, i also use it as an external gps receiver for my touchpad. It just seems much easier, i'm already paying for the data plan why the hell should i pay some ripoff carrier another 30 bucks a month for data on my tablet. This would however be nice to see if an external dongle will work.
all valid points. I currently tether to my phone as required, however work has issued me with a 3g/4g(LTE) usb dongle that i would like to be able to use (in addition to all the other 3g dongles i have lying around).
I've seen the wifi adapters on ebay that you can just plug the usb dongles into, but to avoid shelling out extra $$ i thought i'd see if there was any in-built or easily implemented support for usb dongles.
Having seen the cheap chinese/ebay tablets running GB with usb dongle support i figured surely there must be drivers out there that could be adapted to work with ICS.

Looks like someone did it with a wired dongle for the Touchpad...
http://forum.xda-developers.com/showthread.php?t=1552102
So maybe someone could do the same for a 3G dongle?
And it also looks like there's a way to a 3G dongle working with an Asus Transformer on Honeycomb...
http://forum.xda-developers.com/showthread.php?t=1151097
although it takes quite a few steps and doesn't work on ICS yet.
I also found this...
http://it-depot.net/pages/3G_Setup
But the guide doesn't mention what tablet or version of ICS this should work on. On my Touchpad running CM9 nightlies I don't have a Mobile Networks options. Between the vagueness of the guide and CM9 being an alpha, it's kinda hard to figure out what the issue might be.
I guess your original question was, has someone made this possible for a Touchpad already? And it seems to me that the answer is no, but it eventually might be done. It looks like you're not alone in wanting to get a 3G USB modem to work on an android tablet, if that gives any hope.
Thanks gmkelly.
I'd seen those links before and tried to find that mobile networks option. From what i can tell, it looks like ICS might actually have some drivers built it, but whether they are in CM9 is a different question.
I also kept a close eye on the wired lan adapter thread posted yesterday (?). If a wired adapter can be implemented, maybe it wouldnt be too much effort on getting the wireless 3g implemented...
Forget US carrier restrictions. This feature would be an absolute godsend in a country like Nigeria where a 3G dongle is pretty much the best way to get online in most places.
The only issue I see with this is that a lot of 3G dongles are only Windows / Mac compliant. Meaning that they hate linux or anything that isn't Winbl0wz XP (or 7) or Mac OS X 10.5+. And Android definitely doesn't fall under that category. Just like consoles (which I have seen people try and use the dongles for, too).
However, if you CAN get them to work, you'll be a hero in the tablet community.
3g dongle works with hp touchpad now. Check Josh's PPPWidget forum. I am using a ZTE MF110 with it on CM9 and get better performance than on a win7 machine.

[Q] How to get USB tethering between an android 3G device and Sony Tablet S to work?

Hi,
Has anyone tried and had any success with USB tethering a 3G android device (let's say an HTC android phone) and the Sony Tablet S? Are there apps or kernel modules that are needed for this? I'm hoping to cut down on the battery drain on both devices by turning off the wi-fi radios and just using USB. I'm having trouble loading the mii.ko and usbnet.ko modules, though the rndis_host.ko module is loading ok.
Thanks,
A
No. Would need drivers and all sorts of troubles. Try wifi teethering or bluetooth. Wifi works good for me
Ok, that may be so, but I'd like to know if anybody has tried and succeeded, or if not could point me in the right direction. I'm not adverse to troubles and drivers, I'm adverse to inefficiencies. I've used wifi tethering and it consumes too much power on both devices. The resources (i.e. usb on-the-go) are available and we might as well put them to use, right?

Good plan, but at the same time you will find that the Tablet is charging your phone.... LOL i do it all the time. Check in the dev section, but still don't have many devs. Maybe with the (hopeful) growth in sales of the Xperia Tab S we will se more 'action' here.

Unrooted yet Lollipop coming, adhoc patching, usb hardwire tethering other androids

Have we gotten to the point where the Android tools in general use are available for a capable android computer, like say a Z2 tablet or one of several Galaxy phones just to name a few?
My Z2 has 23.0.1.A.4.44 which I understand is not rootable. At the same time the Lollipop update is supposed to be just any time now. Should I root it now or wait and see what happens after the update, which I'll assume will be nothing to make it easier to root. Any suggestions as what to do? Root now and see if it will update and keep root or just wait? I can hardly stand the idea of this not being rooted.
Has anyone had any luck making a Z2 connect to adhoc wifi? I've studied the OLSRD patch and a few other methods and I'm a bit unsure about which method would be best and easiest. In fact, I have several devices I'd like to be able to connect to a simple adhoc wifi.
If anyone can point me to a ground level and upwards networking tutorial that doesn't carry a person too fast that is slow in that department, I'd appreciate it. I know the WLAN on most all of my androids tested will see adhoc wifi but the wpa supplicant thing seems to be the problem that google has ignored to the point they say it's now moot. I wish I could say I agreed.
Going further, if I make a usb micro to micro cable to connect these various devices, would it even be possible to hard wire tether the Z2 (and/or) other various android devices that way?
The only cables similar I can find are micro a to micro b and they are mostly called OTG. My understanding is that the Z2 will accept a or b and so will some of my samsung handhelds. I don't guess I know for sure.
Have we gotten to the point that hard wiring androids to each other would ever be of benefit? The wifi direct, near devices and NFC beam things on my devices equipped seem hit or miss at best if not inexplicably inoperative. Can you wirelessly one click root an android or flash a rom?
Please pardon my ignorance and thank you for your tolerance. I'd like my android world to be easier and more logical when it comes to simple things and it would be nice not to need a windows PC to tinker with my androids.

Ad-hoc WIFI is supported via WIFI DIRECT, look under Settings > WIFI > Advanced > WIFI DIRECT
Advanced is the 3-dot menu in the top-right corner of the screen.

Yeah support seem to be a hit and miss thing.
And as far as I you can not root a phone wirelessly.
I don't see that wifi direct is the same as actual adhoc. I have no less than 5 wifi direct devices, not all activated, and in the case of my spg512 cannot be activated, and it doesn't seem to work on any of them.
However, my pc's have zero problem seeing and connecting to the wpa supplicant skipped broadcasted wifi from my rooted s4 via barnacle.
Turning that off and trying the wifi direct with the same s4 and any other of my devices, gets nothing. None of these devices have any problem hooking up to starbucks or hotel wifi.
I have to wonder also if the infrared on the devices so equipped could be made to transfer data like a nearly 10 year old windows mobile phone can.
I must be doing something wrong or have many broken devices because the ones I can get to pair, all fail to transfer files to each other.
Of course the wifi direct sure isn't going to tether any of them to the internet.

Reverse Tethering on T-820 (Option not available)

I want to be able to plug my new Galaxy Tab S3 (T-820) into my desktop computer or laptop via the USB C cable and not just move files back and forth, (which works fine), but ALSO have access to my desktop's internet connection through USB. I don't want to use WiFi.
I have an Ethernet to USB C dongle, which works fine, but it doesn't allow me to share files or charge my tablet. I'd like to be able to do all three at the same time.
In many of the "How To" articles out there where "Reverse Tethering" is described, they helpfully list the various buttons and widgets to click in order to enable this feature. However the authors always refer to menu items and buttons which don't appear under my tablet's settings. They're not just greyed out. They're simply absent. So that doesn't work.
Neither do any of the various apps on the Google Play Store and elsewhere which promise to provide reverse tethering. They just don't work.
SO...
Being new to the Android (and the smartphone) universe, I did a ton of homework and have so far figured out how to...
Root my tablet. (Done!)
Wade through the swamp of TWRP, ODIN, etc., while tripping spectacularly over the various speed bumps and permission walls provided by the likes of Samsung and Google's paranoid anti-theft (and it would seem from my use case, their anti-happiness) feature set.
Successfully install different flavors of Android.
Install both Magisk and Xposed and try their tethering unlockers with negative results.
After a week of little sleep, I've managed to get through all of this torturous nonsense and amaze myself by not having bricked or totally spoiled my tablet. It still functions! After all the warranty-voiding BS I've crammed through it, I'm feeling quite lucky.
However... I still don't have the ability to tether/reverse tether!
I've learned a lot, but I still feel mostly like a dazed and confused script kiddie (remember when 'script kiddie' was a term? Well for me, it still applies nicely.) I'm trying my level best, but various elements of this whole exercise remain opaque. This is my first post in any forum asking for advice because I finally hit the outer bounds of my DIY energies and pride.
So, if you will indulge my humble request, what I want to know is...
1. Is my tablet even capable on a hardware level of performing a reverse tether, or has the manufacturer locked that feature out so that even a ROM which promises to turn it on will fail to do so?
AND...
2. If it IS possible for a ROM to turn on the tether/reverse tether feature, which one is it and where can I find it?
2a. If there is another solution.., what is it?
I'm currently on...
Android Version 8.0.0
Samsung Experience version 9.0
Kernel Version 3.18.71-13482624
Build Number R16NW.T820XXU1BRE2
I bought this unit off Amazon; it was a refurb and I didn't get it through some cellular provider nor do I have a phone plan. I don't know where this tablet originally came from, but it was all new, sealed and shiny in the box when I got it.
Thanks!
I can appreciate losing a week of sleep. But I don't understand why you need to reverse tether. Enable WiFi and there you go. I think the last time I needed to tether a device through my laptop's internet connection would have been the 1990s.
FWIW the USB-C connector on the TAB S3 is different because if you want to drive an HDMI monitor you need a DisplayLink chip enabled dongle and DisplayLink Presenter app running on the Tab S3. Whereas on my TAB S4 I can just plug any regular old USB-C -> HDMI dongle and display on the monitor. So odds are trying to get reverse tethering working on the Tab S3 is going to be an exercise in futility.
Hi there, you still looking for reverse tethering for android? i found & use this for a while... you can check github link here : https://github.com/Genymobile/gnirehtet
working well on my S3.
Holy cow, it works!

What...? It worked?! Thank-you!
It's hard to believe how much effort and research I'd put into this, how many promising fixes I tried and which failed. In truth I'd given up weeks ago and found myself scornfully looking at the expensive tablet by my desk, wondering if I should hang on to it for its limited uses or sell it on eBay.
Thanks for posting! I can now do what I wanted with this machine.
For others, just follow the directions on the github link provided in the previous post.
I just scrolling around to find fixes for wifi issue - it connect & reconnect every times when on my office connection. Since me unable to use wifi, i try to find the work around using LAN connection. Then i found that.
Happy i can help others. Cheers mate.
