[Q] Won't connect to PC?

I'm having problems getting the phone to mount 100% of the time in Mass Storage mode. Occasionally it'll connect, but especially it seems when it's plugged in with the EVO it just won't get a connection. It charges fine, it shows up as a drive, but it doesn't give me access to any files or anything.
I'm using the USB drivers from the Samsung webpage specifically for the Epic 4G.

Disable "USB Debugging"

Try that. For some reason I couldn't mount my phone as a drive until I turned off USB debugging. Settings -> applications -> development (i believe)
I have windows 7 64bit and it works every single time now. I've transferred tons of stuff. I never even formatted my card.

RE
I couldn't get it to connect (driver installed incorrectly etc) when connecting the phone to the front port of my PC, but it worked immediately when I plugged it into the rear of the desktop.

I can contest to this disable usb debugging.

USB debugging has been disabled, used multiple ports, etc. and still having problems. Reinstalled drivers, manually added drivers, nothing is biting. I've also tried disabling driver signing, doing everything I can with that off and still nothing. Windows 7 Ult 64-bit in case you're curious.

Just got my Epic and had the same problem. Oddly enough though it worked with other USB ports on my computer, just not the front/top ports.
I've seen this problem before, I just cant remember where though.

Hmm, i have a Mac and the memory card is not mounting at all. had to take out microSD card and use USB card reader. Had no problems with other HTC Android phones connecting to my Mac (Hero, Evo).

Install USB Driver for the Epic.

Epic USb drivers? I doubt thats needed. Maybe a updated USB driver for your computers USB ports.

Try a different usb cable I had the same issues changed the cable and no more link issues at all.

This is a rather common problem it seems like. I fixed it by using a powered USB hub. Also try using a different port, certain ports seem to not have the power needed even if the phone looks connected.

[Q] Which USB cameras work with nook color?

Is there a list of supported USB cameras that work with the nook color's USB host mode? Especially ones that have build-in microphones - I would like to start using Skype with the nook color if possible or at least be able to take a picture/video from time to time.

I could be wrong, but I don't think any webcams work with the USB host mode yet.

Hey. I apologize if I'm asking a question that's been answered. But how can I get USB Host mode enabled? Do I still have to use that special kernel? If I do, the link for it doesn't work anymore. I have the micro-USB gender adapter, NOOK Color Tweaks, Cyanogen Nightly 8-31-2011, and that's it. Do I need something else? I have looked everywhere and can't find a comprehensive guide for enabling USB Host mode for USB peripherals. Please help me!

Yeah, that thread is a bit of a nightmare. USB Host is built into the nightlies now, and I think it has been since before 8/31, but you may want to grab a more recent nightly. You enable USB Host in the Nook Tweaks app. A lot of peripherals won't show up unless you run them through a USB hub, ideally a powered one.
I think a lot of things need to be mounted via terminal commands, too. I'm just offering a digest of what I've seen in the thread, though--I haven't gotten any of my peripherals to register on the NC, but then I wouldn't expect any of them to register without a hub, except maybe my card reader.

Usb Host Mode Problem

Let me start this thread by stating that I DID have my Nook Color, booted off an sd card with cm9, working with my usb powered hub connected to a mouse, controller, flash drive, and keyboard. But through a possible hardware error on my part, I cannot get it to work anymore. I'm fairly adept at modifying my Android Devices. I used USB Host Controller and looked through my dmesg logs and the only thing I found of note was it recognized my 7 port hub, but had it suspended. I attempted to enabled/disable USB Host in my Terminal Emulator with commands found in the USB Development Thread but it simply did nothing. Reading logs, etc. is not necessarily a strong suit of mine. So finding what MAY by the problem, has been a bit of a pain the past 2 days. However I will detail my problem below:
Items used:
- 7 - Port USB Powered Hub from Micro Center
- OTG Cables bought from Amazon.
- Nook Color (With various roms. Notably Cm7.2, CM9 (Unsure of nightly version), AOKP Build 40):
- Belkin USB Keyboard and Mouse
- PS3 Controller
- Sandisk 16gb Micro Flash Drive
Apps Used:
- Nook Color Tweaks
- USB Host Viewer
- USB Host Diagnostics
- USB Host Controller
About 3 days ago I decided to set up a station for my tablet as a mini-computer. I had successfully connected a mouse and keyboard (independently of each other) previously but I wanted to go ahead and use my powered usb hub and get a real mini-computer experience on my android tablet. These are the results (All tests include the use of an OTG Cable to connected to either the USB Device or Powered Hub):
Test 1:
Rom: CM 7.2 Kang
1 USB Device Connected: Mouse (Yes), Keyboard (Yes), Flash Drive(No), Game Controller(No) - All enabled via Nook Color Tweaks
Devices Connected to Hub: No
Test 2:
Rom: CM 9
1 USB Device Connected: Mouse (Yes), Keyboard (Yes), Flash Drive(No, I believe it required more than 100mah to power), Game Controller (Yes) - All worked by just Plug N Play.
Devices Connected to Hub: Yes (The Mouse, Keyboard, Flash Drive, and Controller worked simultaneously)
[To Note: Inbetween this test I pulled the OTG-Cable connected to the hub without un-mounting the flash drive first. CM 9 wasn't happy and told me to properly un-mount my sdcard first before pulling the cable. (I bowed to my Android lord and said "okay".)]
Test 3:
Rom: AOKP Build 40
1 USB Device Connected: Mouse (Yes), Keyboard (Yes), Flash Drive(No, I believe it required more than 100mah to power), Game Controller(I have not verified) - All worked by using Nook Color Tweaks. Did not Plug N Play.
Devices Connected to a Hub: No (However it will charged).
Problem:
Looking back at my 'To Note'. Somehow I believe this has caused the problem. Since then USB Host Mode has only worked with a single device NOT connected to the USB Hub. Although my Nook will charge connected to the powered hub with or/without the hub turned on it still will not allow a single device to worked. I've used Nook Color Tweaks with my USB Hub plugged in with both USB Host Mode and VBus External Powered checked (In all 3 roms; AOKP, CM 7, and CM 9) and the only successful attempt made where the HUB and all 4 devices worked were in CM 9 for about a day and a half. Then I pulled the OTG Cable without un-mounting the flash drive, and alas, no-go with the Powered USB Hub.
USB Host Controller tells me I have USB Host Mode enabled (In all 3 roms) yet going to connected devices shows nothing. USB Host Viewer (In all 3 roms) shows nothing connected. And USB Host Diagnostics tells me various things that I'm willing to list here if needed (Host API, Kernel, etc), yet each time the USB Devices connected during the diagnosis, they are not recognized.
Troubleshooting:
- I've plugged my usb powered hub to my computer. It works just fine with each device connected, at once, or together.
- Each device works independently connected to my computer (Keyboard, Mouse, Flash Drive, Game Controller).
- I can still connect a keyboard and mouse independently to my nook with Nook Color Tweaks, but Plug N Play does not work.
- I've attempted both USB Host Mode off of SD Card (CM 9) and EMMC (AOKP Build 40) where Plug N Play only worked with SD Card (CM 9).
- The Kernel for all 3 roms has been 2.6.32.xx or greater (Cm 7.2 used Dalingrin's OC kernel, AOKP Build 40 uses 2.6.32.59, and I'm unsure of CM 9's).
At this point I'm at a loss and I am looking for help. I've done a fair bit of searching (Admittingly too much during work) on these forums. As stated in the beginning of my post, I had it working with all 4 devices in CM 9 booted off my sd-card, since then I've switched my EMMC from CM 7.2 Kangs to AOKP Build 40 (hawt) and successfully used both with a mouse and keyboard. But I cannot get the powered USB HUB to do anything BUT power my Nook Color.
Thank you for your responses and if you need logs, links to the items, apps, or roms used,(forum wouldn't let me post all of them) screenshots from apps, anything, I will respond as quickly and as efficiently as possible.

Have you considered on just reinstalling the whole build over from scratch? I think the USB host is part of the drivers in the kernel layer and that kernel layer might have become corrupted. If you got wifi and audio working on that nook color then the likelihood of having a hardware problem by that definition becomes less of an option, the USB hub is driven by the CPU. So if you got cyanogenmod up and booted, this points to a possible kernel opps. You stated you had it up before. I don't work on kang and AOKP builds so how is the stability of the usb host mode for those builds? Sounds more of a software issue and not some hardware issue. Unless you just like trying to decompile software for a learning experience for yourself. Did you do a hardware hack for your nook as stated in this thread here? http://hackaday.com/2010/02/10/usb-host-mode-for-droid/
Also make sure you disable all of your apps on your device, that is another possible cause, we don't know what type of apps or mods you have made.
Unless you got support to your USB the only way to find the problem is to decompile your whole build through ADB. Logs will not find the problem if its in the kernels. Or are you using ADB through wireless? Check this thread here if you haven't seen this thread yet. There is an app that gives you USB host support already. http://forum.xda-developers.com/showthread.php?t=1468531
UPDATE Aug 31st. 2012. Check thread here on USB host support. http://forum.xda-developers.com/showthread.php?t=1459892
If you want more experience on how android operates, you can start off by building your own cyanogenmod on your computer, the cyanogenMod wiki here shows you how. http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Compile_CyanogenMod_(Linux)

USB 3.0 problems?

Hey I have been trying the usb 3.0 on my phone and computer obviously i have usb 3 on my pc and when ever i seem to open the file browser for my note using windows explorer it crashes almost instantly (Windows explorer is not responding) havent tried messing about with any drivers as this shouldnt be the issue, ive tried using different usb ports and enabled the usb 3.0 option on the phone?
Sent from my SM-N9005 using XDA Premium 4 mobile app

So are you using Win 8/7? A recent upgrade to OS? Using Win 8.1? Do you have USB 2.0 ports that have this crashing problem when you try and reproduce the issue or have you only tried the USB 3.0 ports only?

I have same problem

I have same problem.If some one can help me, please help me.
I am using it on win 7, usb 3.0
when i am using note 3 on usb 3.0 with usb 3.0 mode selected at phone end, my pc explorer stops responding to it.
As soon as i switch to usb 2.0 at phone end(MTP Device) it starts working, even if i connect it to usb 3.0 port at PC end and switch it to MTP, it starts working.
any help is appriciated.

it's not as fast as i expected

This happens to me on literally every Android phone on every PC and laptop. XP, 7 Pro, 8 Pro, 8.1, USB2, USB3, makes no difference. It usually takes 12 minutes to load the device, and the second I click anything, it crashes explorer.exe.
It started since they got rid of USB Mass Storage. God I miss that, MTP is sheer rubbish, even iTunes is faster and more stable...

Try to reinstall your usb 3.0 hub drivers.

usb 3.0
Hey there, I have had the same problem. And here is what worked for me and hopefully work for you. In order for the USB 3.0 to work on your note 3, you have to activate developers mode. If already not. Settings-->General-->About device-->And look for "build number" (second last option) tap it seven times, it should give you a message each time you tap that says "you are 4 steps away from becoming a developer" and after you have tapped it 7 times it should say "developer mode enabled" and in about devices you should now have the dev options. Select it and check USB debugging. Un-check it and unplug your USB and re-plug it in to the USB 3.0 port i should connect as a media device. :laugh:

Has anyone found a solution to this issue? Obviously USB Debugging was not the solution. Is this more of a windows problem, android problem or samsung?

Android.
Specifically, it's the Mass Transfer Protocol.
The device is connected as a Media Device now, meaning it isn't actually a drive. It can only support one action at the same time (So if your virusscanner is set to scan external media, you can forget opening it, as it's 'busy', resulting in a freeze and a crash.), has to work through a thousand little corners just to open, and everything done has to be converted first.
Whomever cooked up that protocol should have his head bashed in for his stupidity.

So...?
Still no solution ?
Personnaly, at least the debug mode trick made the 3rd option appear as I connect the device, but as soon as I try and check it, well an error message comes "impossible to use USB 3.0".
Is there an alternative to this mass storage protocol? is this the real reason why they didn't put usb 3.0 on the note 4? No one can make it work? not even with tweaks, xposed modules, etc?

Please help me connect Asus z380m to Win 10 usb for adb / Tasker

EDIT - solved! I've never noticed that apparently some cheap micro usb cables will not work for adb data connections though they work with other devices such as external drives just fine. Grabbed a 3rd cable out of desperation and it hooked right up. What are the odds? Learn something new every day.
Either I'm being thick or this is just fubared - I have a non-rooted Asus z380m running Android 7.0 firmware ww_v5.3.20_20180809. I cannot for the life of me get it to connect to any of my pc's in order to enable write secure settings for something I'm trying with Tasker (turn gps off requires security?). I've Googled forever, tried every usb driver I can locate (including unsigned installs), ensured that Developer mode, USB debugging and USB config on device is set to MTP protocol. NOTHING seems to enable usb connection to pc. The only way I've been able to get files on & off device is through Asus file manager utility that provides web interface (which sucks).
I also tried a Win7 laptop with the "latest_usb_driver" package and no joy there either.
I'm not the most savvy Android guy around, but doing IT for many years I have more than the average clue. Except here apparently.
Any insights would be _greatly_ appreciated.
