I did a search and found that no one has posted this problem on this forum - I'm the only one ??
My prime use to hooked up with my PC with no problems. At some point recently (I'm thinking the recent ICS update) my PC & Prime had a parting of ways. Now I plug in the Prime and get 'USB device not recognized'.
Downloaded and ran Asus Sync hoping that a driver vanished but no luck.
I'm running Windows 7 (64 bit). Has anyone else noticed the same problem and if so - how did you fix it ?
Thanks
I have three computers, and none of them even recognize my prime anymore, not even in Device Manager. This started after I got it back from RMA.
I, myself, am not particularly concerned about it, since I'm just waiting for the Infinity to come out; the Prime I will just pass on to a family member. If the Infinity was going to be released in the far flung future, I'd send it back.

Did you try this for the Prime ? I did not see the Prime on the supported list.
Thanks
I Have the problem as well...thought it was the cable but half happy to see it probably isnt
hey everyone, and I'm so happy to see this thread, but have you guys had similar issues to Mines?
Hello Everyone, I'll try to short and to the point. I've been searching xda/google/androidcentral on and off since maybe early Februrary and still nothing, maybe someone has some awesome insight.
So my computer won't detect my TP anymore for file transfer. It did maybe the first month or so though.
Here's what I've tried so far, with no luck.
- Different Computers - Different Cables - New Asus Brand OEM USB Cable - Aftermarket USB Cable - Different USB Ports (Front and Back of Computer) - USB Debugging Mode - Uninstalled Drivers on my PC to try and get table to re-install it. - Factory Reset (multiple times with and without auto-backup) - Connecting From KeyboardDock to Computer
I convinced my cousin to buy a TP and Dock the other week so I also got to try some extra stuff.
- I plugged His TP with His USB cable to His PC and it connected fine.
- I plugged His TP with His USB cable to MY PC and it connected fine.
- I plugged MY TP with His USB cable to His PC and it wouldn't detect.
- I plugged MY TP with His USB cable to MY PC and it wouldn't detect.
I also tried his TP with my USB cables (both oem and aftermarket) on my PC and it connected fine.
Here's Some additional Info, that may be helpful.
I was previously able to connect to my HDMI ports on my TV via micro HDMI, but that does not work anymore either.
I've seen a few people mention serial numbers, so here's some Info, not sure if it's the correct info.
My TP - TF201-B1-CG - S/N starts with a "B" His TP - TF201-B1-GR - S/N starts with a "C"
I thank you all for your time and any insight is much appreciated.
Called ASUS support - I'm the first that they have ever heard that problem. They suggested a factory reset but first I must back the data up. Never done a factory reset, I hope Voodoo will keep the root.
When I finally try it - I'll let you know what happens.
Cool thanks NewbieKeepItSimple, I hope we get this sorted ou!
Hey everyone, I have some more interesting info regarding the USB issue. I didn't want to suspect this as a problem, but yea it looks like it may be an actual bad port on the TFP itself.
My reasoning is that I got my free GPS dongle in the mail today and it won't work. Anyone else test this yet?
Another Question, as far as RMAs go, do we HAVE to call in? Anyone know for sure? I know there's forums, but trying to kill 2 birds with 1 stone.

But you guys are charging fine? Just not connecting to the PC's? Have you had a good look at the connectors both on the cable and the Prime, nothing obvious? You all have uninstalled and re-installed the drivers right? Or maybe tried the universal naked driver utility?

Yep, charges fine. I couldn't see anything obviously wrong with cables and connectors.
As far as trying universal naked driver, I'm pretty sure drivers aren't the issue since I tried a whole different TFP with the same computers and cables (stated above) and it connected and installed the drivers correctly.

My Prime was sync'd at work with my contacts and I put movies on from my home PC. Now neither PC can communicate with the Prime.
There is somethings with the Prime and USB ports that seem a little goofy. I have a USB memory on my keychain that I use for my work files. One of the things I wanted to do with the Prime is access and work on my files during business trips. The work USB memory is 4GB Fat 32 but the Prime can't see it even though all other computers can see it. Plug in an older 2GB memory - the Prime can see it. Plug in my Apple iPhone - the Prime can see it. Plug in some other USB memories no problem but my work USB is invisible.
I really can't see any reason for the Prime to suddenly become invisible to computers but I will try the factory reset once I get my memory 64GB SDcard next week.

that's so frustrating. factors reset didn't work for me but I'm wishing luck to you.
Ok.. something to try before going directly to wiping your Prime...
First, try plugging it into a different USB port. This will cause the PC to try and load a new driver.
If that fails, click Start, right click on Computer and select Manage. Look for an entry called "Portable Devices" and under that "Transformer Prime TF201".
If you don't have that at all, then the system has failed to identify the device entirely.. try it with another PC (take it to a Best Buy and plug it in.. ). If it fails there, then something has changed in your Prime. If you've flashed the ROM, it's possible that's the problem.
If you DO see the entry, but the PC isn't recognising it - right click on the entry for the Prime and select 'Uninstall'. On the dialogue box that pops up, check "Delete the driver software for this device" and let it do its thing.
Unplug the Prime, then plug it back in. It should download a new driver for the Prime. Hopefully this will fix the problem.
I've never heard of an Android device's ADB USB port failing - it's entirely possible of course - but we have five here.. which is pretty amazing.

I'm not holding out much hope either but who knows. The ASUS is rooted but I haven't flashed anything. Another tack I tried is using the just the tablet then keyboard connection but both give the same results.
If I'm connecting to two different spots that on the Prime (dock/Tablet) and there are two different interfacing chip sets involved. Maybe it is a software bug that is screwing up how the Prime addresses the USB (protocol).

hmm even if it was 2 different chip sets it'd still have to go through the main one. it'd be great if it was software based issue

Hi All,
I have a U25GT-C4W running Android 4.4.2 KitKat. I have managed to root the tablet.
The tablet has a separate charging DC 5V in jack as well as a USB Micro OTG connector. It connects to PC fine and I am able to detect it through adb.
It is also able to detect OTG devices connected to it such as a Keyboard, Mouse and a USB Stick/Flash Drive.
Out of all the China tablet clones that I have tested, this one has a peculiar behavior. See picture attached to understand this behavior.
If I connect DC 5V plug to tablet, tablet starts charging.
Then when I connect a USB Mouse, the tablet STOPS charging after 5 seconds (Not normal behavior).
Then when I remove the USB Mouse, tablet starts charging again (after 10 seconds).
I have tested other tablets with separate DC 5V jack and they do not show this behavior. This is not normal.
Tablets I have tested:
ValuePad VP112
King's Hong Kong H704A
When these above tablets are charging with DC 5V, and then I connect USB Mouse, these tablets do not stop charging like the Cube U25GT is doing.
Has anyone else experienced this type of issue? Has anyone solved it? Are there any custom kernels/system that I could use for this to solve the problem? I don't usually post questions on the forum because I usually find the answers I need after searching for a while, but this has been a baffling situation.
Hopefully someone will answer. Let me know if you have any questions about my issue.
Thanks.

I have the same tablet, and have same problem.
I need to solve this problem, because its important for me.
i use this tablet as a part of multimedia system in my car.
so i cant plug any device via otg to tablet
Please help us...
Sorry for my bad English
Go for another tablet.
Hi,
The short version is: No. I couldn't solve the problem.
I spent about 2 to 3 weeks trying to solve this issue. I started from garnering information on kernel sources for the MTK tablets (the SoC which the Cube tablet is based on), trying to find the source code for it, compiling it and flashing it to the tablet. I tried contacting the people at cube-tablet.com. I spent a lot of time explaining them the problem hoping they would give me some indication as to why this was not working. I spent a lot of time contacting people in various forums who had some exposure to the Cube tablet. But that proved fruitless as well.
In the end, I just gave up. We just experimented with a various other tablets and settled with one that charged as well as worked with OTG.
Thanks.

Thanks a lot for your answer wickedmask.
It was disappointing for me. The whole project was built on this tablet by me.
You can see from the photos below:
There's an interesting variable in build.prop:
# USB Charge only function
ro.sys.usb.charging.only=yes
Have you tried to change it to "no"?

Hi,
I'm looking for a solution to this problem: I have an ASUS Google Nexus 7 which I mishandled and broke the screen + digitiser to the point where there is absolutely no touch response - The screen however IS still visible. This happened several months ago. I've been searching for ways to retrieve the data on the tablet, but all to no avail.
Here's the case:
-The USB port is fine;
-The tablet is not rooted and never has been;
-USB debugging is not on;
-The tablet is on PTP, not MTP;
-I do have the device driver installed on my PC;
-I'm only looking for the media from the device - none of the apps or app data;
Is there any hope of getting back the media left on the tablet, or will I have to purchase a new digitiser and screen + bezel? I know how it all goes together so it wouldn't be a problem if I had to get a replacement, but I would prefer to do it cost-free if possible.
If anyone can help me out here, it'll be greatly appreciated!
Thanks in advance.

Have you connected it to PC to see what is available to view? I'm afraid that being set to PTP may hinder your data recovery efforts.

Yeah, that's why I mentioned it. If it was on MTP (which it should've been ) then this whole situation would've been a lot easier. Unfortunately, because of the broken digitiser, I can't change it either. If i can get remote access to the screen everything should be okay in theory (after I've put the screen back on)

That was one of my initial thoughts, but I was unsure of whether the old-gen Nexus 7 supported OTG and whether you had to have to have a rooted device for OTG. I'm gonna presume you don't need a rooted device for OTG and that my Nexus 7 should work just fine with it since I've had that suggested here, and on Tom's Hardware.

Hi there,
At 4pda, they are writing, that some PX5 units have troubles with WiFi/USB below 0°C.
It looks like my Witson unit (MX2 MCU, PX5, Android 8) suffers from exactly this problem. The last days we had warm temperature and USB and WiFi worked perfectly.
Now I went outside and the issues are back. It's 0°C now here!
Can anyone confirm this issue?
At 4PDA, they suggest a fix by adding a screw-whole + screw to better fix the proccessor unit:
https://4pda.ru/forum/index.php?s=&showtopic=883219&view=findpost&p=77467642
It looks like the processor unit is only fixed by 2 and not 3 screws and especially the two most outside pins, which are responsible for wifi and usb suffer from loosing contact with cold temperature.
I'm keen on trying to hardware fix. But I'd like to know if someone has experience with this?
Christian
Seems like a easy issue to check for and then apply if your unit has this issue. You might help others by testing the solution and posting result/images.

I now read the whole post in an ugly into german translated version.
The theory with the processor unit is not confirmed, the people over there discuss about powering issues for the usb ports, temperature-related problems etc. No finally confirmed fix seems availbale yet.
As my unit is less than two weeks old, I am claiming warranty. At least I purchased trough an UK dealer with paypal, so first I hope for a replacement.
If I don't make progress with that, I'll open the unit and look for the issue.
If someone elso would have a confirmed working fix, I'd try it.

There's another thread where a few of us have been researching this problem. The fix is posted HERE. There's no need to open the unit.
There's links in that thread to the 4pda forums where they explain what the issue is also. Long story short, it ends up being a manufacturing defect relating to the USB host controller. Newer versions of the board don't have this problem. But I can confirm the above fix does work like a charm, I've tested it several times.

Hi there, will comment in the thread you linked. I have running that fix with tasker already but still have partial drops of the host controller. I'm also working on a tasker task to switch WiFi on as soon as it gets off.

If anyone is still interested in a hardware fix, my KSP units have a 5-pin IC for USB current limiting and I found if the part is cooled, the USB will not turn on when it wakes up. I replaced one with a TPS2001DDBVT, same package and pinout but better specs. It passed the bench test. I haven't gotten around to installing the HU yet.
Update: I installed the unit with replaced ic, and it behaved differently, though not yet correctly.
It's worth noting, a Dasaita HU which has not exhibited the low-temperature wifi issue has the same USB hub chip, but a different (much larger) crystal attached.
I installed the newer usb hub chip as mentioned in the other thread. No more low temperature problems, however if I reboot the unit via software (with a rooted app), the wifi does not come on. One must reboot with the reset hole. Do not try this while driving.

Hi
I have the same problem on my Dasaita bought on september 2018!
which upgrade do you suggest? hardware or software?
the problem occurs only with the dab module connected to the cable with 2 usb, while the single USB cable, which I connected the 4G wi-fi router, always works.
If I will installed the hal9k ROM, could I fix the problem?
thanks

I'm going for HW repair. I've ordered GL852 sop28 from ALiexp (0,55+3,4USD shipping).
Dasaita knows about problem with GL850, but they proposed to replace chip by myself or to send them SOM board and wait till they resend it back. well, i'm definitelly not happy with their response.
I hope that replacing USB hub will solve at least one other problem - random unmounting usb drives and problems with copying files from usb to sd-card.

I changed the gl850 ssop28 with the better version gl852g. Now I have no real problems anymore with my xrc unit. There is a software fix in hal9k 3.1.1 in the mod settings but it was only working when it was not to cold. I had in cold days allway to wait and reboot the system ...

No, it's not really easy, but without no skills before I did it. I just watch some desoldering and soldering videos and tried a bit with an littel another broken board with a ssop8 socket on it. I desoldered a lot and soldered a lot on it and then I change the chip on my mainboard.

I used a soldering iron beacuse I din't had a hot air station.

Yes, I did. It's my picture at the feedbacks.
For me was it a good shot.
Hi there, i have no idea what is going on with the cellphone, since i used it for the first time i tried to charge the battery without any success, i reboot it while the usb-c was connected and it did charged, so now every time i want to charge it i have to connect it and reboot it. Also if i disconnect it after rebooting and connect it again it wont charge until i reboot it again, seems like it doesn't recognized the usb unless i reboot it. Could someone help me? Thanks
Have:
- Android 9 PKQ1.180729.001
- MIUI Global 10.2 Estable 10.2.2.0 (PEJMIXM)
- Model M1805E10A

Install a custom Rom or MIUI10 latest beta build. If problem persists then problem is hardware related.
Been facing the same issue, @drchau did you find a fix for it ?
It is a hardware problem.. seems like it is somewhat common. I had the same issue last week. Tried several stock and custom os. Then realised it should be a hardware issue. Mine had same behaviour ( reboot to charge ) and then problem with otg not detecting. And usb c cable is recognised in only one way.
So booked a slot for service . Went to service today. Found three customers with same issues , and then the service center replaced my usb sub board and others too. Took one hour total. And everything is fine now.
Total cost is INR 700 for board + INR 350 for service + 19% GST. = 1250 INR.
They won't replace the port. It's a whole sub board . They replace it. You will get it for free if under warranty.
I have this problem with my Mi Max 3. I have to reboot OR for some reason it will charge via an OTG dock without rebooting (odd ... If I plug the same usb c cable in directly it doesn't recognize it.
A couple of times when I unrooted and reverted to stock unrooted, the charging issue went away.
I realize that many here are convinced this is a hardware issue but I also routinely disable/delete a lot of crapware and system apps via ADB .... Can't help thinking there might be a coded dependency issue.
I am in the USA so getting it serviced isn't an option ... I have 3 Xiaomi phones and would love to add a Poco F3 when I can afford to, but these charging issues are being reported with great frequency and I am hopeless at soldering.
If anyone knows of a repair shop in the USA they trust with their Xiaomi products I'd be grateful to know the name.
Thanks!

There's probably a couple mosfets and what not on that PCB. Maybe bad design or a manufacturing defect caused a solder crack or trace failure. Maybe a component.
These boards are usually inexpensive.
A relatively easy fix if so.

It could be (most likely is) a dependency especially if it happened right after the edits.
I prefer to package block rather than edit them out. Mistakes are easily corrected... most times.
Don't attempt soldering anything in these devices unless you know how to, not the place to learn.
Many though aren't soldered in, they're connected with ribbon cables more commonly. See a device tear down to find out.
A good phone repair shop should be able to handle it.

Thanks for your reply.
I'm pretty sure from video teardowns that the parts involved in the MM3 require soldering (there's some kind of board involved with replacing the port)
I still love the Mi Max 3 but it isn't worth a spendy repair because the carriers here are shutting down 3G and HSPA+ soon which only leaves me with FDD LTE 4 (not great where I live).
Repair shops aren't as expert in the states sadly ... most people here buy their devices from carriers.
I needed a camera replaced on my old Max but they didn't want to order parts so I ordered it and did the replacement myself (but only because I didn't have to solder).
If Asurion insurance from Amazon covers global phones I'll get my next Xiaomi insured. Too bad Xiaomi won't just let us ship at our own expense to their service centers in China or Europe.

Many times you replace the whole port PCB. If it's soldered on it could be a pain even with the right tools/experience.
You could try a factory reset to undo the disabled apks to see if that was it.
Thanks, I've tried factory reset and it helps for a little while. For now its still usable ... Rebooting to charge isn't a big deal. I do find it odd though that I can still charge via OTG dock without rebooting.
The bigger issue is what to buy to replace it. I don't trust Miui not to be buggy anymore and I have grown to hate constantly having to disable optimizations that inhibit sms, email and even calls (if I try to use TMO towers... AT&T MVNOs seem unaffected ).
I wouldn't mind doing all those steps once but my permissions don't stick for very long.
The TCL 20 might be worth a look...or maybe Realme if I see one with a bigger screen... I'm wedded to large screen models, mid price at best, with NA LTE band support ...
TCL also has a couple of LTE tablets with decent specs coming out ... but LTE tablets for USA export almost always ship with the dialers disabled so you can't make calls.
I'm trying to out till the end of June. By that time, hopefully the Poco F3 bugs will be resolved. Retailers aren't even shipping it here yet.

After the factory reset you need to find the akp that triggers this. Reviewing the most recent running and/or cache processes can narrow down the list.
Use Package Blocker PD MDM to clear the data in suspect apks. Unlike clearing the data in settings PD MDM leaves no nulls behind. Those silly nulls can mean big trouble.
Since it keeps returning the offending apk may be amenable to being package blocked depending on its function/dependencies.
This is how you find it.
Android Setup is a prime suspect. I cured a similar C-port error message like this by deleting the null marks in its data which showed as zero.
Happy hunting
