After 2 days of struggling about the USB connection issue, I think maybe I've found the reason... Just write something here so that someone may see this in the future when searching around...
CONCLUSION FIRST:
It's caused by lack of power supply of the USB ports
If you believe me, you can skip the part below and try use a USB port in the back of a desktop and tell me if I'm right
Just leave me some feed back...
---------------------------------------------------------------------------
So here's how I found it...
My observations:
1.Cannot connect to my 2 laptops in all modes and with all drivers I can find, showing "Device not recognized""your device is malfunctioning".
2.If I pull out and back the cable several times, it may recognize at some times. This connection may last for only 1 sec or several minutes, but won't be long and stable since I always stuck in the middle of large file transferring.
3.The e-sata/usb combo port worked better than the other two in the left side.
If it's the problem of driver, then with some of the drivers, it may work better. however, nothing makes a different.
If it's because of system, I have XP on my old one, and Win7 x64 on the new envy 14, and the result is exactly the same
so the observation #2 made me believe that maybe it's a hardware issue, either my phone or my cable is broken. what excluded the phone is that I got a replacement yesterday and the replacement doesn't make a difference. So the only thing left is the cable.
So I brought my phone to the school PC center and used the desktops there. still not recognized when i plug it in one of the usb ports on the front. So I crewed on the desk and finally reached a port in the back, and bang!
It recognized in 2 sec.
So i pull the cable out and connect again.
still 2 sec.
try transfer a large folder to it. lasted 5 mins, finished smoothly.
So I went upstairs to another desktop there.
Exactly the same result!
and both of the two desktops don't have any drivers installed beforehand.
---------------------------------------------------
So now I believe that if you only need to use mass storage, no driver is needed. windows will automatically install an universal usb driver for it and it should work.
All the drivers are ment to get connection in Kies/ADB/downloadmode.
And the reason why some guys never get connection issue may simply because their computer are designed to give more power to the usb ports.
As for my envy 14, all the usb ports i can reach come from a usb hub inside, which has 6 ports connected to. and 3 of them are already used by internal bluetooth chip and etc..
Also...some phones may need less power to activate the storage chip...
So just tell me if I'm right~~~leave your comments here...
This could be possible. I've used devices in the past that would act up randomly before I moved the usb ports around. You could try to use a double head usb and connect that into your phone to confirm your theory. But really, as long as you got it working, good for you.

SpeedMod Q Big Mem

Interesting theory. I had an old HP Laptop from '05 I used with three usb ports, and the number of usable/recognizable eventually turned into one. I just thought my laptop was acting crazy with windows 7 and drivers... because I now have a tower pc and the connection is solid. I do use a port on the top though, although it's never given me any issues. So...moral of the story is... this phone's usb is kinda funky.
And if you're a n00b and reading this, if your computer EVER says "device cannot be recognized", etc... BEWARE OF USING ODIN3 on this PC! I had a similar mishap right as it was flashing on sbl.bin... I am lucky that I don't have a Super Amoled paper weight.
Yes that's what I'm gonna try~ need to buy one online though, may bring the result back in couple of days.
Motherboard
Always go directly to the motherboard for a hot USB port
I believe that many of the FAQ/Bible threads mentioned using a rear USB port many months ago.
Hi!
Got my Note yesterday, now I got a problem, again. I can't get it work on USB 3.0 no matter what I do (I'm sure about this but I ask this anyway: am I right that SM-P905 have USB 3.0?)
Okay, to the problem:
When connected to USB 3.0 I don't have option to choose USB 3, I only got MTP and PTP
- I updated Kies 3
- I reinstalled drivers (from Kies)
- I have 2 USB 3.0 ports on my PC so not so many to test but:
USB 3.0 works on my Note 3 (SM-N9005) on both USB-ports, It also works well with my Note Pro USB-cable
Note Pro doesn't work (don't give even option to choose USB 3 mode) on any of these two ports. I also tried both ports using my Note 3 USB-cable, but still no luck
So any ideas?
ps. I got ASUS motherboard and I found out someones having similar problems with their Android devices. Reason was ASUS Ai Charger -utility, but I don't have that one never ever istalled on my PC. Oooh, and one more thing, I'm using Win 7 Home Premium (x64)
---------------------------------------------------------------------
Updating BIOS and reinstalling Windows did the trick, now it works like it should
What exactly makes you say it doesn't work? Are you completely unable to transfer data to/from the tablet to a PC, are you not seeing a difference between transfer speeds using a USB 2.0 cable vs a 3.0 cable, OR is the appearance of everything working there but you are wanting the USB 3.0 nag screen to pop up to give you an indication that you're indeed using USB 3.0 ?

When I connect Note to PC USB 3.0 port, pull down notification bar and click USB notification, I get ONLY option to use MTP or PTP. USB 3.0 is not listed there as option. I also transferred about <10Gb size file to Note and it took about 50min, which really is loooooong time..
Okay, here is screenshot about what I meant. Can you please say how it's in your tablet.

Same - Mine connects MTP and I can see it and transfer files but on my tablet I get a Icon in the top tray that says connected to USB 3.0
Same here, when I'm getting a USB 3.0 connection to my PC I'll get the 3.0 indication in the notification screen.
I can't get 3.0 to work with my rMBP but it works with my Windows 7 based workstation and I can definitely see an increase in file transfer speed to the tablet when the USB 3.0 cable is used in a USB 3.0 port. Just did a test from a hard drive on my PC to the tablet, 2.1GB file transferred to internal memory on the Note Pro in 1:18 using a USB 2.0 cable and 0:48 using the stock USB 3.0 cable so I'm getting about 45mb/s with 3.0 and 27mb/s with 2.0.
Okay thanks. Tomorrow I'll check again if notification bar shows USB 3 or not, can't remember right now (still got thought that not). I'll get back here and tell if it's working or not.
EDIT: Yup, no USB 3.0 connection, in notifiction area there is that standard USB icon and it's not saying 3.0
EDIT2: Is there some way to find out if Note charges using USB 3.0? Shouldn't the 3.0 be a lot faster on recharging than 2.0, but how I can know which one it uses?
Sent from my SM-N9005 using XDA Premium HD app
Okay, back to subject..
Does USB 3.0 affect anyway to charging speed? Like if I use stock wall charger with 2.0 or 3.0 cable?
What's your charging speed? I did test and from 50% to 55% it took 15 minutes and from 50% to 65% 45 minutes (which makes average 5%/15min)
To charge I used stock wall charger and stock USB 3.0 cable. I didn't use my NP while charging and mobile data / wifi was OFF
Can you please check how fast is your Note Pro to charge? I still can't make my note to work on 3.0 mode when connected to my PC and I'm trying to find is the problem on my PC or Note before sending this to repair
How about trying Gsam Battery Monitor and observing the charging characteristics that way. It will give you charging current.

With wall charher charging current is 1900mAh, which is normal I think.
Now, if I plug my NP to my computers USB 3.0 port, I get BSOD --> PC reboots and I plug again --> now it works, but still not on USB 3.0 mode. So it could be with drivers or something, tried again install device drivers with Kies 3 but no luck. What could I do? I don't have skills to remove all the drivers and start from clean table (any other way than formatting my pc and that's not gonna happer for a while )
Any ideas?
Okay, just tried with laptop (Win 8.1) and my NP is ok, it connected using USB 3.0.
Now what, if my external HDD and Note 3 works on my own PC via 3.0, what I can do to make my Note Pro work also??
Problem have to be with drivers or something..
Mine doesn't show the "Use USB3.0" option that my Note 3 shows, but it clearly says "Connected as a media device via USB3.0" in the notification bar. (See attached screnshot)
Also, it just copied 1.03GB in 16 seconds from my laptop to my NotePro.
Clearly they removed the USB 3.0 setting from the menu, and it is now done automatically.

I'd start with USBDEVIEW. Google it. Run that with no android devices connected to the PC. Uninstall all drivers related to any android device and reboot the computer. Then try again.
If that doesn't work, consider repeating that, rebooting and then updating the chipset drivers for your motherboard.
After that, I'm out of ideas.
Us Mac users have the same issue; the tablet is simply not recognized as a USB 3.0 device on my rMBP which is running Mavericks. It doesn't matter if I'm running windows as a virtual machine in VMWare Fusion or not so I'm thinking its at the driver level of Mavericks.

I copied 1.42GB file from my USB 3.0 HD to my ext. card - that took 5:52.
I just can't get 3.0 connection to work with NP (see attachment), Note 3 works fine.

Thank you for help. I uninstalled all drivers related to Android and/or Samsung, restarted my PC, connected NP and still not working. At this point I restarted computer again but that didn't help either... Where the heck can that problem be?
I also tried killing all processes that I knew I can safely kill from my PC (In hope if some program/process is doing harm for USB 3.0 connection) but no luck..

Hm.... Have you updated your PC's USB3.0 drivers? Have you tried using the Note 3 cable?

I updated them twice, just to be sure. I got 2x USB 3.0 ports on my PC.
My external HD and Note 3 works well with both of them. And Note 3 also works with NP 12.2 cable.
Just my NP wont work no matter which port or cable I use.
On my friends laptop NP 12.2 with the cable that came in the box works well, immediately connects as 3.0 device.
I think I'll quit with this. Don't have the knowledge find out where the problem is.. I thought maby BIOS update might help, but since everything else works fine, I wont do that because the risk of totally f*** up my computer.
But if anyone here got any other/more ideas, I'm listening

You said you had an ASUS motherboard, right? I'd go ahead and update the BIOS, it's pretty fool proof with the newer ones (which you have USB3.0, so it's a safe assumption that it's new enough.)
I also have an Asus motherboard, funny thing is, my Note Pro does show the USB3.0 indicator in the notification bar, but I'm copying files over right now via Linux and it's copying at 9.9MB/s. That's pretty horrible. Added to that, my Note Pro won't charge from the USB port on my computer, but it will from the wall charger. It has a big red X over the battery when plugged into the PC. So I'm not sure if that's somehow related.
Another thought about both of our problems, is that maybe the cable is a little loose or something is in the port-hole. I know mine was a bit flakey for a bit there (as in I would plug it in, create a folder... then tried to rename it and it said it couldn't access the device... I had to try it three times after unplugging and plugging it back in.)
It doesn't make sense though that it's a BIOS and/or driver issue if you also have a Note 3 and it's working through USB3. I know on mine, when I tried it in Linux (can't recall if I did under Windows), it was extremely flakey there too. The Note Pro just autodetected it, but still copied slowly. I'll have to try that under Windows as well now.

Yes, you may want to update your BIOS.
(For the record, I'm using an Asus N76VB with the factory BIOS, no issue).
Hm, maybe a silly suggestion... Are you using any type of USB charging setting? I know some of these Asus motherboards come with an option to overvolt the USB port to enable fast charging.

Not related. A USBport doesn't supply enough amperé to register as charging. Even my old Galaxy Tab 2 10,1 has that issue.

I have that issue with my Note 3 and even my TF700T since day 1. It's an MTP bug. And now since 4.4.2 I can't rename anything on my Note 3 without explorer.exe crashing. Different pc's, different OS's, different cables, no difference.

I did read somewhere that Asus AI Suite (program to tune up voltage or something for usb charging) can somehow do "harm" to USB3 connection, but I don't have that one even installed.

Well... I too see that red x on top but my tablet charges anyway (slowly byt still charges)
The funny thing here is like I said: My Note 3 works perfectly when plugged to USB3, but my NP doesn't like recognize that it's plugged to 3.0 port. It just acts like using 2.0. Same PC, same cable, different device.

Yeah, I know mine isn't charging because I watched, even after plugging it into my computer, it slowly go from 70% battery down to 65%.
When looking at what is hogging all the battery, it's the retarded Indexing service. I'm still in the process of seeing if there's a fix for that, but it really seems like it's having an issue (which would also explain why mounting it on the computer is flakey, since they could be trying to read the same file systems.) Oddly, my Note 3 doesn't have any of these issues (except actually mounting as USB3). In fact, I was starting to suspect my PC at work had crap USB ports, but it's just the stupid Blackberry cable (it only successfully charges the blackberry, not my Note 3 or anything besides my mouse that I've plugged into it.)

My Windows 8.1 PC would not recognize my Shield Tab with the supplied USB cable. Charges fine, though. However, the Shield Tab is recognized with either cable from my Samsung Note 2 or LG G Pad 8.3.
Anyone else experience this? Looking for feedback before contacting Nvidia.
My tablet is not recognised on Linux either, whereas my nexus 7 2013 was. It did have Franco kernel installed, which might make it mount the file system better than stock.
I am able to see mine in windows and my linux vm

Actually, I stand corrected. My tablet is visible in LInux in MTP and PTP mode.
Have you tried the usual tricks about swapping USB sockets, and checking your Connected Hardware in Windows.
I also have USB Debugging on, if that makes a difference.
The Shield cable is the same as any other Micro USB cable, so if you have another one lying around for another phone, give it a go first before going to the hassle of contacting Nvidia.

Thanks. It's definitely a bad cable. I've tried USB cables from 3 other devices and the Shield tab is recognized by my PC with each of them.
I recently purchased this tablet from Walmart. It was appealing because it was cheap and looked to have everything I needed in a cheap tablet. I have not however been able to get my laptop to recognize the tablet when plugging it into the computer. It has two ports, a full size USB and micro USB, on it but neither work with the laptop.
The full size USB does nothing when plugged in. It does not recognize it at all. The micro USB does recognize but says the device isn't recognized and it will not give me options to update drivers and comes up short when troubleshooting. With RCA's outstanding customer service I have gotten nothing but silence. I really like the tablet but I am a bit frustrated with the inability to load my files on it.
Does anyone have any suggestions?
Thanks,

You didn't say what Windoze you are using. The first thing I normally try is to install PDANET. I don't even know what PDANET is for, but it has a LOT of drivers, and normally fixes issues I have connecting strange phones and tablets. Just go here http://pdanet.co/ and use the download for Windoze button. This link also seems like my solution: http://joyofandroid.com/how-to-install-usb-driver-for-android
Good luck. Android access from windows is more or less a crap shoot, but it can usually be made to work.
