Usb not recognized and keyboard stange attitude - Transformer TF300T Q&A, Help & Troubleshooting

Hi guys
I've juste fix a screen of TF300T for someone
My problem is the following
Scrren working but not the touchpad
That's not the issue
The issue is that some keys one the Asus keyboard does not working (1, backspace...)
And, the worst, whan I want to connect the tab on my PC, I got a windows message saying that it does not recognize the device
I'have tested on 3 different PCs
I think this could be the main USB dock even it the power loading is working properly
can someone help me ?
Thanks

Hey, I'm experiencing the same problem. For what ever reason my tablet is stuck in an infinite boot loop and It refuses to connect with my PC. It charges fine also. BTW is there any way to flash a recovery or firmware to the device from an sdcard?
Sent from my SPH-L900 using XDA-Developers mobile app

Finally that was effectively the USB connection wire between the mainboard and the usb dock connector
(nappe in french, don't know the english word)
It works fine now
Not sure you can flash from sd card until you don't have access to the system command.. :/

[Q] the weirdest crashes

well, since this is not OS or model specific i'll place the question here.
1 colleague plugged in his HTC Desire at home and his pc crashes, and his internal mirror RAID became invalid. after the reboot (boot disk was a separate disk) he tried to connect his phone again and no problem at all!
another colleague plugged in his HTC Desire (bought a few months after the one described above) and the pc freezes (no immediate reboot) and the cooling fan from the power supply started blowing like there's 30 volts running through instead of 12. YES REALLY! i was there! after a reboot, again, no problem at all!
me, connecting my HTC HD2 to my pc and suddenly it starts rebooting. after the reboot, again, no problem at all!
immediately afterwards i tried plugging in the usb cable pressing gently in all possible directions in the usb plug. tried different usb plugs. tried with or without my phone connected on the other end. there was no way of repeating anything i wrote in this post.
so the question. does anyone recognize this?
what other phones and phone OSes give this problem?
could it be win XP? win7? vista?
anything?

Problem with The USB Connection

Hey XDA,
Two days ago I updated my transformer to 3.2 after a 2 months that I didn't used him, after the update I noticed that when I connect the transformer to my PC, the PC doesn't recognize him and the transformer himself didn't open the Asus Sync app to find the ASUS SYNC in the PC.
Its not the USB cable because it charging and its new.
Its not the USB port I tried another device.
Its not the computer \ OS , I have 2 windows on my computer and it doesn't work in any of them.
I tried to wipe twice , it end up with a lot of lost data that I forgot to backup.
I tried it in APX mode and its doesn't work either.
I tried USB Debug ON/OFF
I tried Reinstall drivers.
I really dont know what to do I search in google hours and I didn't find anything.
Thanks alot for helpers!
BTW sorry about my english.

Any idea ?? Its like the Asus Sync app in the pad doesn't work.
Does that happend to you after updated to 3.2?
probably still isn't the cable but just because it charges doesn't mean the cable isnt broken. The data uses different cores to the charging.

Not the first time. After a reset it started doing that.
Same problem here after updated to 3.2 no more working sync.
PC does recognize the transformer self open can open files on the SD card. But the Asus Sync app can't find the Transformer on the PC.

Where did you get the usb cable? I can't seem to find one anywhere.
What's wierd is that i never "tortured" the cable to account for it to break...
It's always in the same area, attached to the charger (only take it of to connect to the pc, wich is like, 15 cm away from the charger), no pulls, no sharp bends... but it fells fragile on the connector (dances a bit from side to side)

I got it from Asus ,their cables have a lot of problems... SOMEONE has any idea? I am sure that there's a way to fix that, but I dont know what...
usb cable is not the problem.
Can connect to the PC en transfer files to/from the mem card.
Just restored a partition image form the PC witch was working before...
So problem must be in the transformer...
Cleaning was not working too

If you have the same problem like I have wipe won't work either. I tried this.
Everyone has any idea please? You don't know how much calls I had with Asus until I got that.
I waited two months for that cable...
I tried rooting a couple of months ago & was unable to because I couldn't get Asus Sync Installed correctly. My problem was that when I connected my Transfomer to my computer the computer wasn't seeing it like a flash drive. I installed & uninstalled everything numerous times. I used about 3 different programs to cleanse my registry & delete all of the temp files. I use AVG & disabled everything that I could disable. Last week I was finally able to get everything working.

Thanks for your response, when you connected the transformer to the PC did the Asus Sync app\icon opened in the transformer? You can see this next to the clock, did you saw this before you fixed the problem ? Because when I bought the pad it was there, but now it doesn't.
Thanks for helping, please write back if you had or hadn't the icon.(Of Asus Sync app).

Indeed, I would also like to know if you had the asus sync icon on the tablet. Mine doesn't appear.
Will try to clean registry and all that. see if it fixes anything, will update post when I get home and test it.
I downloaded now app called "System Panel" after I open this under "Power Information" menu I saw "USB - Yes", "AC - No" when I connected the pad to my PC, Now I am sure its not the cable . But if I want for example to make a hotspot from USB connection I cant , he says "USB Disconnected".
I tried reinstall drivers and everything you said, but now I am sure that this is the problem is from the Pad.
Someone have any idea please?

Same thing with me. Usb yes.
And ccleaner didnt help either.
Hey guys I'm on my phone so I don't have the actual apk names but do you still have the two apks that relate to the "phone" installed? I had a problem similar to this but fixed it by reinstalling one of those. Not sure if this will help but you can give it a try. One of the apks is phone and the other is voicemail I think ... They are both tied into bluetooth and usb I guess .... Like I said not sure if it will fix for you but worth a try.

I have tablet without 3G and I don't have these Apps, and if I have how do I reinstall them? They are system apps...

Same here, no 3G support. If you could give at least the name of the apk so we can search and try it would be awsome
Cable Problem
In my case it was a cable problem (more precisely connector that is pluged in device). The connection isn't tight, the device was charging, but USB data transfer was not working, either it doesn't recognize the device, or if you manage to find a connector position in which it recognise it, usb connection is so unstable that it will stop working if you move it a little.

device not recognized by windows

When I connect the Transformer to my computer I get the message "USB device not recognized." Have read many threads on this subject. The main solution seems to be to RMA your Transformer and get a new one sent by Asus, but mine was refurbished and is already out of warranty. I have tried the Asus Suite and also the alternative "Naked" drivers. Nothing has worked.
Was previously running on Revolver 3. Just upgraded my system to Revolver 4, doing a factory reset and full wipe, hoping that might solve the problem, but it has not.
I have read that some people with a rooted Transformer have solved this problem by "re installing the bootloader," nut I have been unable to find information on how to do this. Is this an option in my situation and does anyone know or could anyone connect me to a link describing the process?
Assuming I cannot get my Transformer recognized by my PC after reinstalling the bootloader, what would be the most convenient way for me to transfer files between the two?
Thanks for your help.
Update on the problem:
Last night I decided to experiment with the USB connection, pushing and moving the USB connector once it was connected to the computer. And guess what? For a split second my device got recognized, and actually showed up in Windows Explorer. Then a second later I was getting the same "USB device not recognized message." By fiddling with the connector I was able to get this split second recognition about four or five times, then I gave up. It's just not good enough to have the device recognized for one second!
Anyway, based on this I conclude my Transformer hardware and system must be fine, it's just the sync cord is poorly made--well, it doesn't seem to be the cord, but the USB connector specifically that is defective.
The cord does work to charge my Transformer when plugged into an electrical socket, so all the more odd that it malfunctions when attached to a computer. I've now discovered several threads describing a similar situation: cord worked for charging but stopped working for computer connection. So looks like what we are dealing with here is fairly common manufacturing defect with the USB connector on the Asus Transformer cord.
I won't know for sure until I get a new cord, but once I do I'll post an update as to whether or not the problem is solved. Hope this can help someone else in the same boat. At least worth trying a new cord before RMA!
hello
perhaps stupid questions, but :
- Did you tried to check/uncheck "USB debugging" ?
- did you tried to communicate with ADB ?
i have the same problem with mine. i just ordered a new cable. hopefully this fix the problem so can root and install new ROM
Sent from my Transformer TF101 using xda app-developers app.
reset the system ,and then try
reset the system to default ,and then try
Go to device manager on your laptop and uninstall and delete drivers for Asus transformer, restart your laptop and reinstall the driers then it should work fine
Sent from my Transformer TF101 using xda app-developers app
something similar just started happening, but only after i rooted it.
my tablet used to connect to Windows 7 just perfectly. but immediately after root, (with the same cable that was used to root it) is no longer recognized by Windows 7. haven't tried a different cable because i didn't have another handy at the time, but i will try to use another cable.
then i've tried to uninstall the drivers from Device Manager, and downloaded the USB drivers ZIP from the ASUS site... "ASUS_Android_USB_drivers_for_Windows.zip"
but when browse to the INF file during the detection part, i get an alert message that won't allow the use of the INF file.
any help would be much appreciated.

[Q] MTP/PTP Connection problem

Guys, I have some problem with my Note II, the MTP/PTP function stopped suddenly like 2 days ago. When I connect to PC, the phone doesn't pop-up let me to choose USB connection mode, and in PC it just showed up as 7 CDC's in device manager, this is weird, I am sure that I have the correct drivers installed. Before that my phone keeps pop-up that dock is connected, but I doesn't own a dock though. So I guess it is USB flex cable is faulty, I replaced it and still having the same results. Charging, USB OTG, ODIN mode works fine though, just I am unable to connect my phone to PC. HDMI out I don't know because I don't have the cable. When I ask the shop they said there probably is something fried on the mainboard IC. Is it true? MTP mode is quite important to me man... Tried other kernel like AGNi and select UMS mode also not working, previously it is working though. My phone is out of warranty, and the Knox warranty also voided. Should I sent to Samsung SC? If no go I might change to OnePlus One.
Now I am on stock ROM also not working. :crying:
did you try updating the drivers
through windows automatic updates?
or did you try with win7 or win8 or linux?
Xp has always troubled me with incorrect or missing drivers

Cenovo MiniPC

Hi guys. Help greatly appreciated.
I bought a Cenovo MiniPC from Gearbest 2 months ago and from day 1 I've been getting blue screen errors. I immediately reported this to Gearbest and as you can imagine with the time difference between here (Sweden) and there (China) I was getting slow responses. Cut a long story short they 1st offered me a $20 refund from a $90 device, I accepted at the time as the errors have not appeared for over a week and thought it could be the end of it. 2 weeks after this the errors came back and it wasn't just blue screen on startup but it would freeze up during a session. I again reported this demanding for a full refund and they refused. I opened a dispute with PayPal and after a while they offered me a further $20 which I refused, they then sent me an email and said if I close the dispute they will give me a full refund. I was hesitant whether this was a scam but I went along with it and to their word I got a refund 3 days later.
After I got my refund I thought I may as well try and fix it myself now so I started in BIOS and fiddled with some switches for the emmc, one was 'secure erase', I don't know what was going through my head or what I thought the outcome would be but I enabled it and restarted. Now it just boots into BIOS and I am guessing the reason is that the emmc is now blank.
So ive now got a minipc with a blank emmc, I have loaded a bootable copy of Windows 10 setup to a usb and forced a usb boot in the bios but nothing happens.
I have opened the case to look for a emmc card I can take out and put in my laptop to reformat with an os but I couldn't find anything, there was a metal grill on one side that looks like it is hiding stuff and it is impossible to lift the grill off.
There is a tf card reader on the side so i am thinking that I can extract a Android image onto the card and boot from the card but I am not sure how and whether it will work.
Can i get some assistance in this please.

Hello, I've got same problem, 0xc000025 error code, arrived my tentative to upgrade the PC to Windows 10 (the PC arrived with 8.1 installed)
No way to boot my USB in the bios. Have you solved? Someone can help?
try and format the usb stick to 4k sectors before using the win10 media creator, think that's how i did it
Thank you for replying and sorry for the late response.
Have you got the same mini pc?
How do you format stick into 4k sectors? What format did you use (Fat32,NTFS...)?
fat32, in windows format dialog box its "allocation unit size" set to 4096
to boot from usb the stick has to be recognised as bootable before u can run the bios command to override boot device
yep i figured it out thanks. ive now got another problem and this is totally my fault if it cant be fixed...
in bios i unchecked the option to use integrated graphics so now when i boot i see nothing

intesting, daft thing to do tho, u could try borrow a usb gfx card?
Does anybody know how to reset the bios, because I've disabled the usb ( stupid x 10000 ) and I cannot use the usb ports (mouse and keyboard)
same problem here... I've disabled xhci support and no USB right now. The problem is that removing the battery does not make the bios to default.
I've still got the issue with no picture. I need to reset the bios but not sure how. Or maybe I can connect it to my laptop and get it working from there
yo. just got myself a cenovo mini pc 2, and it runs windows 10, but it's not legit. That bothers me, so I want to run android or linux. You guys mention that it's running a BIOS, but i think perhaps the mini pc 2 is running non-BIOS/EFI, because there's no preboot screen, and USB drives don't boot up at all.
Hi !
Did anyone got a chance at installing another os ?
I have a Cenovo mini pc 2 and I had troubles with sound. I had no issue for a week or two and then (maybe windows update, who knows) the sound would switch to the speakers output instead of the hdmi one. (it was plugged on my tv) so I decided (stupidly) to uninstall the audio components with the hope that windows would redetect and reinstall them with better drivers. Well, that didn't work and now in my device manager are two unknown components which don't work and I have no sound at all. If anyone found the global drivers for the device, or could make me a screenshot of their devices panel...
In the meantime I would probably try my luck to install openelec or kodibuntu on it but I couldn't manage to boot on bios. Did anyone tried using the Advanced startup option of windows 10 ?

I still have the problem with no graphics.
I know the problem as I disabled the onboard graphics in bios... I know **** head move.
I have tried to remove the lead leading from the bios to the motherboard in hopes it will reset it but nothing.
Is there anything I can do from USB do you think? Such as flash a new bios.

I have a Cenovo Mini PC 2 with 2GB/32GB. BIOS/EFI/set-up is accessed via pressing F2 after boot. Sometimes it will accept the F2 request, sometimes not. Not sure if this is an issue related to the keypress timing after boot being critical, or the unit being generally fussy (maybe selection of which of the 4 + 1 USB sockets for keyboard is critical?). Only wandered around the BIOS settings a few times but there was all manner of Android-specific options available.
Strangely, when the F2 key is accepted, a message is flashed briefly on the screen saying "Esc key pressed" or similar, as if the "Esc" key was the BIOS access key.
The NexBox T11 InsydeH20 UEFI / BIOS / set-up options are near identical to the Cenovo Mini PC 2. There is a video walkthough of the Netbox T11 Setup Utility although it does not mention the very first screen and options seen when F2 is pressed. The Cenovo Mini PC 2 very first screen titled "First Page" can be viewed at

I initially had issues attempting USB boot of Macrium Reflect with my Cenovo Mini PC 2. Eventually solved by one or more amendments of changing brand of USB stick, using Rufus to generate the bootable USB stick via formatting to FAT32 with 4096 bytes cluster size, and disabling fast UEFI in settings. USB stick was inserted into the Mini PC 2 and UEFI / BIOS was accessed by pressing F2 immediately after boot. From the first setting screen, "Boot Manager" was selected and the USB device was visible and able to be highlighted to boot from.
Hi,
Can someone please share the wireless drivers for the minipc2?
I did a fresh windows 10 install and can seem to enable wifi and device manager the wireless adapter shows an yellow triangle.
I've tried with SomeoneYouNeverKnow drivers but it didn't solve this issue...
Thank you

if anyone has the drivers for this device please share them i would be grateful and if needed i can make a guide on how to turn this little device in to a full windows computer its locked on windows 8 in the bios and most settings in the bios is locked to but i have obtained bios editor tools for this american trends i will give it a try later once i have full gpu control the rest i do not care as it will be used with bluetooth but intel hd drivers or the device if would be appreciated
