i have tried to update to this radio twice now. both times after updating my computer will not recognize the phone after updating to the newest radio... any help would be appreciated
i dont think that has anything to do with the radio so try this....
1.take off any programs for your phone (exda-net, easytether)
2.reinstall htc sync(most current)
3. turn usb debugging on on your phone
that worked for me so maybe it will work for you
edit: i used the search function and came up with this!!http://forum.xda-developers.com/showthread.php?t=654940

thank u very much
After updated to this radio, I've experience buggy USB connectivity (where if I start to charge it, the device will [sometimes] think it's connected to a usb device, after unplugging it will not detect it's removal).
I've also had the touch screen flip out, where it will not detect my actions at all. The way I fixed this was to connect to a machine where it then started to respond again...
Anybody else experience this weirdness???

Haven't head that one before. Have you tried another cable? That sounds suspiciously like a cable or USB port problem to me. The radio shouldn't have any effect on your USB connectivity.
sorry for the delayed response -
I used various usb cables and experienced this. The way i worked around this was to use ferrite insulated usb cables only and cut the green and white cables on both ends for the cable in my car. It seemed like the phone didn't like to detect and undetect devices often - all is well again.

All of a sudden my pc is not recognizing phone as a usb drive.. It was working perfectly since day one with this phone but since yesterday it wont recognize it.. And even if it does, it takes a very long time. ive treid uninstalling the drivers and reinstalling, as well as turning debugging on and off. My pc is running windows 7 64bit.. I have also tried different roms and nothing.. When connected in debugging mode, it recognizes it immediately and installs drivers by i still cannot view my storage card.. Any help would be appreciatied.. Thanks
Install pdanet on your computer. When it gets to the part about driver installation, select samsung and voila.

Seconded. I bought a cheap charging kit and the cable would charge but would not allow file transfer. Took it back, bought another cable and it's fine.
Either the phone is finicky about cables, or it might just require a particular type (probably USB 2.0).
I had this issue also last week. I tried another cable and it worked fine.
But now I am having issues with my usb ports in general. Now they just stop working every once in a while and I am required to restart my laptop.
Don't know if the two problems are related.
Try different USB ports. Like the ones on the back on your computer.
I've been having the same issue. I went out to Radio Shack and bought a new data cable. So far all ports on my laptop, winXP pro 32bit, and my win7 64bit desktop have not had problems.
I'm thinking that the USB cable supplied by Samsung is crap. I tested them both out on the same machine, same port; the new one worked fine, while the stock cable only gave me adb access.
I had this same exact problem. I kept thinking the phone was going bad or something. I tried the cable that came with my Epic & the one that came with my Moment, both didn't work... for some reason it worked find on a Mac though. So when I gave my mom my Moment when I got the Epic she bought an extra micro-USB cable and I decided to try that one, for some odd reason, that one worked.
Still don't know exactly what was going on but a third-party cable fixed the problem for me.
Hope this helps.
as title states.
It doesn't seem to be the samsung drivers
as I have uninstalled and reinstalled.
but the Android drivers. I have no Android drivers installed anymore
(the 3 of 4 that installs)
therefore i lose adb connectivity
*This has happened on 2 different Windows 7 installations. (switching between 2 different hdds, on this laptop)
I have usb debug on ofcourse.
I have uninstalled reinstalled latest samsung drivers.
I have installed pdanet drivers.
I have turned off phone, while connected then boot up. still no fix.
I am using acs froyo dk17. But this happened with dk05 as well.
Is there a fix for this?
I've had this problem twice. The way I fixed it was to wipe the sd card. Its a pain but that's what fixed it

If not a driver problem (doesn't sound like it is) the next *usual* suspect would be the usb cable. The samsung cable that shipped with these phones is crap. I got a 6' belkin one on amazon for $8 that has worked flawlessly.
Make sure you're not using a USB port that's on a hub or daughtercard. It should be one that's directly on the motherboard.
I kept fiddling with settings and rebooting both phone and computer and got past this once on my old win7 box. On my new one, I got nowhere after an hour or so. Worked first thing with the same cable on my win xp machine.
Plug your phone into a USB1 only hub, or on the same channel as a usb 1 keyboard or mouse and it will detect just fine... it won't really be useful because it won't be able to flash still (I believe it should detect as a composite device with several facets and only some of those are usb1-only compatible). I believe that the underlying problem is a bad implementation of the usb spec on one of the usb2 only parts, but I didn't feel like digging any deeper. I might try a win xp vm on the same physical hw to see if I can narrow it down to a win7 usb2 + device usb2 compatibility issue. Might be worth making sure our win7 patches are up to date, too.

Thanks for the replies guys.
The usb trick won't work because it's a laptop. And I tried all four of them. I only have windows 7 machines. One being a ultra sff and has like 12 usb ports. It hasn't failed me yet, but happens on the laptop.
It wouldn't hurt to get another cable, a longer one. And my sd is maxed out, I will pull it instead of format.
Thanks all

I had this problem. Plugged into the back instead if the hub and reinstalled everything. Now it's working like a charm on all usb ports. Really odd problem.

I had this problem. I was using a USB extension cable that was a bit long. All the other phones and USB devices worked fine with it. EPIC did not want to. I got the impression that EPIC needs more power from the USB port than most of these other devices. For me, skipping the USB extension cable did the trick. I also used a powered USB hub and that worked well too. You might want to try different USB ports. Some may provide more power than others. Also try a powered USB hub (some are built into monitors) if you have access to one.
I had the same issue with my laptop as well. It is most likely the cable. The samsung one is crap. I tried every port and installed the usb drivers a dozen times with no success. Used the cable from my wifes blackberry and worked on the first try. Just pick up a new cable. Try monoprice.com they have awesome deals.

Also make sure your antivirus is off although that's likely not the culprit. Do you install the drivers as administrator?
Try a new cord. If that doesn't work, try deleting/uninstalling the device and/or hub from the device manager - plug the phone in, letting win7 do its worst by not recognizing it, then open the device manager and find the usb hub. try deleting/uninstalling. unplug the phone and scan for hardware changes. I think this may force windows to reinstall the drivers for the usb hub. Disclaimer, it's been a while since I spent significant time fooling with windows computers so take this advice at your own risk - I'm feeling my way like an old man with cataracts trying to find his way around his long-lost childhood home. in the dark. With unfamiliar furniture. In an earthquake. While in a wheelchair. With flat tires....
My computer did this for a while and now it doesn't although it's certainly possible I changed the cord I was using.
The best way to get drivers to work is install PDAnet IMO..
I had driver problems upon driver problems.. swapped cables, etc.
went through all the motions that you all are describing here and what fixed it for me was installing PDAnet. Worked like a charm.
Hope this helps.
I agree about using pdanet for drivers. Unfortunately this problem isn't with the driver not being installed correctly. I got it on one machine and not another, using the same friver. In fact I got it to work on the same machinewith the same driver ... just different ports (one was stuck in usb1/ohci nd worked, the usb2 port never worked on one machine and a usb1 port never worked on a different one).

This worked for me when I had the problem. This will be the second time I had a usb cable go bad on me. Maybe I shouldn't buy those cheap ones from China...
I've had this problem with numerous cables on Dell E series laptops with 3 Epics and a Moment. For the life of me I couldn't get the phone to be recognized when using the USB ports on the left side of the machine. Plugged it into the ones on the right and have never had a problem. I think with the Dells it's a low current issue on the left side ports. The shorter the USB cable the better off you'll be if it is a low current problem.
thanks but i did alot of that last night and today, uninstall/reinstall drivers, usb hubs.. nothing
i may need to try another cable because i am workign on a friends epic sunday.

It HAS to be the power differences NOT cable.
Same cable as I charge with, plugged into the front of the computer (hub).
Plugged into the back of the computer recignized the first time.
=USB power
In my case, tried several micro USB cables, no dice. Tried my laptop and desktop, no dice. Tried USB hub or direct to PC usb ports, no dice. Device manager shows the right comm port but all the one-click roots i've tried can't find the phone. USB storage has never mounted for me from day one either.
Sigh, never had this issue with any other Android phone.
Finally figured out my issue. I had set it to "modem" while doing something else in an epst menu rather than "pda". Since I corrected that, works dandy.
I feel so stupid.

Hi everyone,
My Nexus 7 at present isn't getting recognised when connected to a PC via USB. This was working the other week (the drivers were installed the first time I connected it via USB), but now when I connect it to a PC via USB the device isn't recognised by the PC.
I have tried this on multiple PC's and the same thing happens on all of them, so it must be something with the Nexus 7 that is causing the problem.
If I go into Device Manager on any of the PC's, with the Nexus 7 connected via USB it doesn't appear anywhere, so I can't go down the route of even updating the USB drivers as suggested for some similar issues on other threads.
I have even installed the Android SDK and installed the Windows USB driver package, but that hasn't done the trick either.
I have also tried installing the Microsoft MTP porting kit, but again this made no difference and the same can be said by switching between MTP and PTP mode and neither have made a difference. I don't have USB debugging enabled, enabling it doesn't make a difference either.
I can connect my Nexus S phone via USB without issue to any of the PC's I've tested the Nexus 7 on, which further backs my thinking of the issue being with the Nexus 7.
I'm running out of ideas, so thought I would throw it out there to see if anyone has any other suggestions before I do a factory reset on the Nexus 7.
Any suggestions will be greatly appreciated.
Further to this I have done a factory reset, which has made no difference.
Any ideas other than going back to Google or Asus?
my N7 has trouble being recognized by different PCs. it is hit and miss. will your N7 charge when it's connected to a PC that doesn't recognize it? my N7 does not show the charging symbol on screen, but the battery percentage increases over time.
Also try a different cable just in case.

Try connecting it as a PTP device rather than MTP.. (that sometimes works for me when I am trying to force it to pick up the ADB device and install driver etc). If it detects it as PTP change it back (to MTP), and hopefully it will be OK.

I had already tried that, makes no difference unfortunately.
I had the same problem.
I knew it was driver issue but where to find the driver?? Looked on Asus' site and apparently the Nexus 7 is the Asus unwanted step-child. Not a mention of it there.
After a lot of looking and a lot of cursing,I found the answer! (It was the cursing that helped!) Install Windows Media Player v13. The needed driver is included. After a reboot, I was able to see the Nexus 7 on my PC and (more importantly) able to transfer files to it!
What happened
I have had the same problem with it not connecting. My n7 does charge when I plug it in but does not show up in my computer when i plug it in via usb. I have tried switching it to PTP mode but it does not find the device for what I'm doing(unlocking boot loader for my nexus 7) I hope someone can help greatly appreciated.

USB Connection To PC Not Detected
Having the same issue here. These two guys as well http://forum.xda-developers.com/showthread.php?t=1851868&highlight=usb+connected Did you also use a car charger? Don't know when it happened for me, but sometime between it last working and testing car chargers it stopped working. Same thing for me as one of the posters says, USB-OTG works, so I would think it's not a physical issue, but how to reset it. Dunno, Any help would be appreciated.
ADB, Fastboot, or USB Connected device in Windows does not work. Computer doesn't even detect, no USB connect sound.
UPDATE:
Installed Glazed Jellybean v.1.1.2 thinking it might clearup the issues with detection of USB and presenting it to the PC. Still same results, USB data connectivity is missing somehow. Just might be some sort of physical damage. Kernel was updated as well to Linaro Motley Kernel v1.1.1.
Help!
I had this happen after using a car charger from amazon. I actually really believe that the charger is the problem, as I had originally got the charger for my recently departed tf101, and after using the charger on that, same problem as what's happening with my n7. Sure, there's workarounds, but it'd be nice to connect to pc for faster transfers.

Same As Above... This sucks.
I am having the exact same problems listed previously & I've tried almost all the same fix attempts with no luck. Like a couple others, mine worked out of the box, then I charged it in my car (using the Nexus 7 cable plugged in to a USB cigarette lighter adapter)... Now, nothing but the indication on the Nexus that it's charging. No indication at all that the computer is even aware a device is plugged in to it. Has anyone found anything? Please, Lord, say it's so!!
I found a fix
Whether this will work for everyone I am not sure.
I took the USB from the hub I was using & plugged it into one of the front ports on the actual tower unit. The drivers were reinstalled and everything is working again.
It may be the Nexus didn't like the hub or it may be that particular USB port threw a wobbler.

Thanks, but I've plugged my N7 in to 15+ usb ports on 3 different PCs & haven't gotten anywhere. No changes.
I did call ASUS support yesterday & was told by the tech support person that they were working on a "PC SYNC" software for the N7, but did not have a release date for it yet. I'm not very optimistic. The tech sounded like she could have been reading from a script. Didn't sound as if she knew what she was talking about. I may take my N7 back & get a replacement.

Hey, do you remember what charger you used? I tried two from Amazon, so I can't tell which one gave me the problems. Here they are:
Arcadia Rapiduo, 10W 5V/2A Dual Port high-speed USB car charger w/ Free Full Speed Micro-USB Charging Cable (IMP80C)
http://www.amazon.com/gp/product/B00845NI8E/ref=oh_details_o00_s00_i01

http://www.amazon.com/gp/product/B00622AG6S/ref=oh_details_o01_s00_i00
Hell, if there are several of us that have damaged devices from these chargers maybe Amazon would help us to get our Nexus replaced.

It was this one at first, then I complained it didn't work, and they sent one that could've come from their own car, the way it looked.
And yes, I know it says "for Asus tf101".
Perhaps there's a "safety switch" of some sort, written into the os, that "shuts down" the ability to communicate through usb after using these car chargers? That may sound stupid, i know.
I don't think it's a pc problem, since the n7 still charges when connected, and also, because this has happened twice to me, with both my tf101 and my n7,directly after using these car chargers.
And, for some reason, I don't believe it has caused hardware damage to the n7. I kind of believe what I said in the first paragraph. Maybe this will happen to a dev, and they will look into the problem.
I suppose rma is an option, but patience is not my strong point.

I have 3 computers and 2 Nexus 7 in household, and one N7 has no problem being recognized by computers and the second N7 wont connect as a MTP device at all, on any computer, with many different cable and port combos. The second N7 was bought just a few days ago and I was not going to root and leave a virgin device, so it was essential to have access to sdcard with computer as storage device. Looks like I am taking it back for replacement...which is a shame because other than usb problem the second N7 was a perfect C70...my first N7 C70 has a minor screen lift, and after comparing the two tabs side by side, a slightly more washed out display.

This was my thoughts as well, thought some of the system files were altered in someway by either that process or my installing usb related apps. USB OTG and USB monitoring apps specifically. However, I decided to try an load Glazed Jelly Bean hoping it would resolve this issue by rewriting the system files, but it was still broken. This has now changed from a connectivity issue to a totally dead unit for me, it slowly started refusing to give a full charge and now not even a response while plugged into an AC Charger.

Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?
No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

every thing ok with s3 but the problem only with s4
please we need help to solve this problem!
Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.
I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

edit: Can confirm pc is now picking up phone. I just flashed the most recent stock rom for my carrier through odin and as soon as it finished updating its prefect now. Might wait another while to root it now and wait for more devs to jump aboard for more roms

I'm on stock, no root.
Hi
I don't know if it may help but i noticed the usb doesn't work when the phone is locked.
I did check 'stay active while charging' in dev parameters and i never got disconnected again.

Tested it out on a fresh copy of Windows 7 and it still continuously disconnect. What gives?

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.
My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

I've been trying all kinds of different combinations of USB leads, phone settings and ports all morning and was just about getting ready to start a new Olympic sport of S4 hurling when I came across this post and plugged my USB straight into the back of my machine and it finally works!! Thank you dirrtpoor for your input - a simple fix, but nevertheless it worked.:good:
I suppose it makes sense that a quad core 1.9Ghz phone would be a power hog.
It wouldn't work on my home PC whatever I tried. Front or back USB ports.
On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.
I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!
Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.
Any way to connect in master storage with out root.

Use a different usb cable and usb port. I know it sounds stupid but there has definitely been phantom problems which were solved this way, even with something as simple as adb commands
i have same problem. trying all the way but always with the same result...
