Interesting problem I have had on and off. When I plug my phone into my desktop, it will connect normally, then a few seconds later it acts like I unplugged it. It's not the rom as it does it in recovery as well(both with usb-ms activated and without). I have HTC Sync installed. Rebooting either the computer and/or phone doesn't fix it, it just goes away after awhile and starts working again. I've experienced the problem FAR less when connecting it to my laptop, it will typically work there and not on my desktop when the problem crops up.
it's like this problem but it's not constantly http://forum.xda-developers.com/showthread.php?t=711616
-Edit- the device also doesn't show it's charging even when it 'disconnects'
I have the same problem. just keeps discontenting over and over it sees it for a few seconds then disconnects reconnects then off again.

Mine doesn't reconnect, it 'disconnects' and stays that way(as if i unplugged it) until i actually do unplug it and reconnect it.

I was having the same problem on my MacBook until I realized the MacBook must be plugged into power. Once plugged in everything was good. I wonder if the Evo demands more power through USB then other devices.
Yeah, sounds like a power issue to me. If you're using a USB port on a hub or on a keyboard, try one on the PC itself. Also, it could be a slow USB port or a bad cable if you are continuing to have issues. Try another computer if you can, and if you still have the problem try a different cable. Still have the issue, reflash (if you're running a custom rom) or contact Sprint for service.
Same issue here, but on a desktop PC (Dell Studio XPS) using the front-mounted USB port (not a hub). Keeps disconnecting/reconnecting, but often takes 10-15 minutes between cycles. Using stock ROM (for now, at least). Will try other ports & another PC and will report back.
Already tried different ports, only motherboard ports
Rom doesn't matter as the problem exists in both android and recovery
Don't have a different cable, however the same cable will work fine on my laptop then not work on my desktop

If it works on a laptop, but not the desktop, then it appears to be an issue with your desktop. Any other USB devices doing it?
I would check your motherboards manufacturer and make sure you've got the right USB drivers, a bios update might be in order as well.
But before all that, I've got an idea. First and foremost, try this:
Go to device manage (either from control panel, right-clicking my computer and going to properties, or searching for devmgmt.msc in the start menu search.)
Navigate down to Universal Serial Bus controllers, double click on USB Root Hub (you probably have 1 for every USB Port, so you may have to do them all.)
Click on the Power Management tab, and uncheck the "Allow the computer to turn off this device to save power." check box and see if that solves your problem.
i had this issue on my hero. it was corrected for me after i did a wipe of data and cache. i restored from titanium afterwards. YMMV
good luck
one thing you might try is disabling sense and using the android launcher. then reset the phone. once it boots up try and connect it to your pc. This was how I got mine to connect. when I was using the sense launcher it somehow blocked that options screen and the default I selected wouldn't stick. once I got the connection to my pc working this way I was able to re-enable sense and it's worked perfectly ever since.
I do not take credit for this fix, someone else on here told me to try this n it worked perfectly.

it was nothing with the rom, since it was doing the same thing in recovery.
it turned out to be the short little usb extender cable that was going a foot and ahalf from behind my pc to the side so i could plug it in easier.

I can confirm this works on my HTC Desire - had been racking up my brains for the past couple of days now with no solution! Thanks a lot. This is on PC with Win7 Ultimate.
Whenever I plug my phone into my computer now all it does it show the little charging light in the top left corner of the EVO, and not the notification asking to turn on usb storage in the pull down menu, or give any errors, and nothing pops up on the computer.
Recently, I started to have usb problems where the notification on the phone was flashing on and off and the usb connected sound on the computer kept going off (like the phone was connecting and disconnecting to the usb port on the computer every second), but I thought this was a cable problem and since I didn't need usb at that moment, I brushed it off.
I'm pretty sure my phone still charges fine because the light goes on. No, It isn't a problem with the cables or the computers because i've tried multiple cables and computers. I don't understand what the problem is because my charging still works fine and I don't get error messages, it's just that usb won't connect at all anymore

If that doesn't work, you may have a hardware defect, and it'd be best to unroot and take it to sprint.

Hopefully you guys can help me out. I'm suddenly having issues with my phone not being detected by my PCs when it is connected via USB.
When i plug my phone into my PC, i receive the error message: "UBS Device not Recognized One of the USB devices attached to this computer has malfunctioned, and windowes does not recognize it." from my Windows XP PC. My Windows 7 PC is unable to recognize the device plugged in.
The strange thing is that even though my phone is not being recognized by the PCs, the phone will still charge.
The phone is not in USB Debugging Mode, and I've gone ahead and flashed 2 separate Kernals on my phone, but i still am having this issue. I have tested this out with 3 USB cables, on 3 separate computers (Work (win xp), Home (win7), and friends(win7)).
2 Days ago the USB worked fine for me as i was able to flash Franco Kernal and JB onto my Gnex, but suddenly it's not being recognized by my computer anymore.
Stumped.....Hoping that this isn't a hardware issue and something that i can fix without having any downtime away from my phone.
Any thoughts?
Try other USB port and other USB cable.
Sounds like you're missing some drivers... Remove the device completely in Device Manager & plug it again. For MTP, Windows 7 should find the drivers online by itself. If you need fastboot access, you'll have to download the seperate drivers for that. I'd recommend the GNex Toolkit in that case since it comes with the drivers included (you'll still need to install them of course )

Thx for the reply,
Yes, I have been using the GNEX tool kit, though not the 7.3 version that was released today. The 7.2 version was being used at home and on my work PC. I usually install the drivers from the toolkit then plug my phone in when done. The drivers have been recognizing my phone but not since 2 days go.
I'm currently trying to find the MTP checkbox in the phone Settings to double check if it's checked, but im having problems locating it.

Ah yes, that is where it was hiding....But unfortunately the checkbox is checked.
This seems like a hardware issue, but I'm not certain since the phone still recharges when plugged in

Could be... Charging doesn't necessary have anything to do with data transfer AFAIK... Do you see something in the Device Manager when you plug it? You might have to right click & do a re-scan to force detection.

Device Managers shows "Samsung Galaxy Nexus ADB Interface". The drivers look to be installed.
Also another odd thing, is that after i charge my phone and unplug it from my PC, it will continue to show that it is charging on the lock screen and in the top right corner of my phone. However if i go into Settings ---> about phone. It shows Battery Status : Not Charging.

You get that when the phone is running normally? I think for me that one only shows up when I put it in bootloader mode. In MTP mode it's just a media device like any other AFAIK... I'll check tomorrow when I'm back on my Windows laptop to be sure . Have you tried putting it in PTP mode? If so do you see the device as a camera or is it the same issue?

Basically the way the Nexus One talked to other systems through USB is completely different from the way the Galaxy Nexus does. The GN uses a new protocol called MTP. Your car stereo probably can't read the files on your phone because it doesn't have MTP support.
Phantom Charging Issue
So I've gone ahead and Fiddled around with my phone for the past day trying to fix my USB issue, and I've discovered that this issue may not be due to USB issues.
Throughout the day when i was playing around and trying to fix my USB recognizing issue, it miraculously started working again. Now I am able to connect to my PCs and transfer the desired files.
Upon this issue being resolved, i noticed that periodically the screen would turn on, on it's own while being off in the locked state. I observed this issue to see what may be causing this, and it is turning on due to my phone thinking that i plugged my micro USB cable in to charge it. The charging indicator on the batter flips on, and even the USB Debugger / MTP Notification is present in the notification drawer.
Apparently this is a known issue with the Battery or charging port with Gnex's. (See below the 2 youtube clips for more details for problem/fix.)

I believe my warranty is void since this phone was purchased in a different country and has had the bootload locked/unlocked a million times. Anyone else have this problem that they have been able to fix manually? Or am I going to have to cross my fingers, ship my phone to get it fixed, and hope the post man doesn't f**k up?

I've had my Nexus 7 2013 for about half a year and it's had micro-usb issues for a month or so before this, but now it is completely impossible to transfer files or connect to my PC as a storage device. The charging icon will remain active, and it will charge, but it simply either doesn't register, or if I repeatedly insert the micro-USB, the "Connected as MTP" will pop up but quickly go away. My PC tries to install the driver but shortly closes after it registers that the tablet has disconnected.
It isn't the cord as I've tried it with multiple, so I'm moderately sure it's the tablet USB port. Is there any way I could fix this without having to get a replacement and if not, how do I go about replacing it?
Thanks in advance for any help. Anything is appreciated.

A couple of my friends Nexus 7's also got its charging port damaged. I wouldnt advise you to fix it by yourself as it's risky. Carry it by a repair shop. I know that the Usb port is located on a separate board and not with the cpu etc so its not hard/expensive to fix.
I have a TV box whit Intel atom z3735f quad-core, 2GB di RAM and 32GB of memory, HDMI, two USB, battery internal, bluetooth 4.0, Wi-Fi dualband(2.4 and 5ghz), preinstalled windows 8.1(i think 'RT') whit Bing, charge whit another micro-usb port!! Model name: Wintel Mini iPC002 (Vensmile W10) Producer: Vissontech [search it for other features] it's a good product for good price!!
Initially i have a problem whit the two USB and i think that it was disable on the bios setup. I procure an otg cable and connect the keyboard in a micro-usb port to finish a pre-configuration of Windows. Then i reboot and enter in the bios setup. Whit my big surprise, everithing is enable!..then reboot and try the two USB, but nothing: don't work!
At last, i re-enter in the bios setup and i can't select or change nothing!..I repeat the operation but i can't change nothing in the bios setup and the two USB don't work!!
Do you say me one way to reset the bios?..or one solution for the problem that i described in this post?
Exist a tool to flash a bios in WinOS for this product whit Intel processor?
Thank you for your time!
Hope in more reply
Best regardes
Soon.
Same problem
Hello novellus2014, i have exactly the same problem : the 2 USB ports doesn't work.
I have test 2 mouses and 2 keyboard. The led on the mouse don't light. Same for the led on the keyboard (caps lock...).
So perhaps there is a problem with the power on the USB ports ?
I can't finish Windows 8.1 install, i am blocked on the language selection of Windows 8.1.
To finish the install you have use an OTG USB cable on the mini USB power port ??
Thanks to send me a message if you found a solution for the USB ports. I'll do the same for you if i found a solution...
a friend!!
hi mediapole, luckily or unfortunately, we have a same problem!!
the answer at your question is: YES!!
i use an OTG cable for finish an initial install.
but or use it or charge the mini pc..a bad solution for use this product
also in my opinion the problem is the power of USB ports!!
also the led of my pen drive is off when it is attached!!
i have send a mail at vissontech and wait for response.
Soon
Same here
Just received my unit and have the same issues and the same oppinion. I think it is about not having power on those two USB ports, maybe a hw problem? I hope not.
I guess I will try to power the unit through the micro usb port, and I will use a bluetooth keyboard and mouse, and a big SD for storage
I am sending them an email too.
are you able to find solution to BIOS issue?

I bought it through Aliexpress. I contacted the seller and they sent me a new firmware that I was able to update into my device. Still the same, no results, both USB's are just dead, there is not even power on them.

Thank you very much. In fact it seems to be an older BIOS (Vx5_bios_20141231_2117_logo.bin) than the one the seller sent to me (Vx5_bios_201501271131_intel.bin), but still I have given it a try.
Still the same, well now I have lost the conection with bluetooth mouse and keyboard, but I guess I could pair them again if needed.
Now I am waiting the dealer to pay me a 50% of the shipping costs back to them. I have 30 days to return the item.

Thats bad... I think its because we tried to downgrade the BIOS from higher version. If you reflash the new one it should restore the bluetooth functionality. If possible could you please send (email) me the BIOS you have?[Vx5_bios_201501271131_intel.bin]
Also, see if this helps...

Sure I can send the BIOS. Is your email published? I can't see it.
I agree that upgrading it again bluetooth should come back, I need to find the uUSB to USB cable again to do it.
I will also check the link you sent, but don't you think that after reflashing the BIOS, USB ports should get enabled if they weren't?

If its a hardware issue then whatever we do it will not get enabled. What i do is i use RDP to this MiniPC if I want to change the settings. That way i dont have to physically connect keyb and mouse to it. I have installed Plex server on this minipc.
I have sent you PM with my email address.
Similar to what I planned at the begining with bluetooth mouse and keyboard. But I'd like to plug my 3Tb disk to it and still keep powered. I have also done some tests with usb hubs, but again no way.
I have tried few things on my mini pc
1) Disabled USB Legacy mode in the BIOS and restarted. flashed the Guleek BIOS BIN file, it flashed successfully and restored BIOS defaults.
2) I have again Disabled USB Legacy mode in the BIOS and restarted. flashed the Vensmile BIOS BIN file, now i cant go to BIOS anymore, it seems it doesn't restore the defaults. I then re-flashed the Guleek BIOS and it started again.
Hi!
i bought 2 days ago a vensmile ipc002.
Im trying to boot with linux usb key, but i have big problems in disabling secure boot...r u able to do it? can you help me?
Everytime it boots windows, even if i made my usb key with rufus, gpt partition, fat32 and every thing i read on the web.
The only way i won is to press restart+shift, then boot/rescue from there by uefi usb....in that way, my pc boot with linux (mate in this case, 64bit version).
Please help me to understand something in bios setup...it seems all disabled, but it everytimes boot windows instead of uefi usb key!!
i tried every solution without success.
I can boot anything ... only win8.1 .
I need to boot linux....is it possible?
Is it possible to flash a different bios without secure boot locked (i disabled from uefi setup but without success...)
Thanks a lot
I have also tried booting with other OS but didn't worked. I will need to investigate more, i will do it this weekend and let you know.

Working Solution for the USB Ports!!!
Hello,
i bought this device last week. and the USB Ports was not working.
so i searched through the Forums, but no solution.
the Solution i found out is, that you have to remove the black Stickers on the front and on the back.
under the Stickers there are 3 Screws on each side. on the front is the WLAN Antenna!
just remove the front plate... pay Attention of the Cable from the WLAN!
then press the electric out to the back side!... disconnect the WLAN Antenna from the Mainboard.
i removed the 2 screws from the USB Port and ... the cable was not connected to this circuit board!!
i removed the Battery (the cable is sticked to the battery) ... pulled the cable to the direction of the USB Ports. and connected it to the circuit board...
then the USB Ports are working!!
just Reassembly the Device after this procedure and all is working
Thomas
Thank for the instructions, if you could post some more pics of the screws (locations) and inside the product it will be great.
I did not wrote this, I found it on Amazon review of the pc.

USB Problem and Solution for the Vensmile. If you are like me you plugged in your Vensmile and were unable to do anything with the plugged in usb keyboard and mouse. There was no power on mine, I checked with a voltmeter and it was dead. I knew it was powered up since it was coming up with the install for win 8. If you are having the same issue as me you will not have a light between the two usb ports in the back. I carefully peeled the plastic protector off slowly (black side with all the ports). This is a piece of plastic held on with sticky tape. This will expose the three screws. Remove the three screws and the main board will slide out. Mine required a tap on each side to start sliding out. You can see the usb board now and just flip the right battery back off the board. I have attached a pic. You can see it either fell out during transmit or was never attached in the first place. Pull up on the black ribbon connection, slide in the ribbon cable and lock the black ribbon connection back down. You will see the usb come back on right away. Slide it back in the case, attach the three screws and put the plastic stick on cover back on.
(I have image of the insides, but the forum don't let me post it)
Edit:
I did it! OMG I did it! It works again! Thomas_Eder and Brittany Thomason thank you so much guys! You are awesome!
1. Use knife to take out the back black bezel. I started from the side and pulled with fingers. Its tough dont worry. It got no scratches.
2. Remove the 3 screws.
3. Tap Tap Tap and the motherboard slide out.
4. On the bottom where the battery is you will have to detatch 2 screws to remove the usb board.
5. See the white ribbon next to battery. Thats it.
6. There is a small cap on the ribbon connector, be careful, open it with nail from the back of his entry.
7. Push the ribbon and close that little lid to hold it in place.
(The usb board will start blink)
8. Dont forget the 2 little screws.
9. Put all inside (watch out for the antenna and ribbon cables).
10. Test. Close. Enjoy.
I made some pics but cannot post them.

I made video with the pictures on youtube - watch?v=OI55cAELoSo
