USB Debugging mode is buggy!

i wanted to mass install my APKs over ADB using android injector, but it seems that usb debugging mode is buggy - it doesn't show my touchpad as a removable drive - it appears as if it's connected via MTP.
any help here?
thanks!

Unfortunately, I have not yet found a way to connect the Touchpad to a computer using USB. I usually use Wifi (AirDroid) or MTP, or just reboot into recovery. I'm not aware that the functionality has ever been implemented. I'm not sure what Android Injector is, but if it requires you to be booted in the ROM's partition and over USB, I don't think you can use it with the Touchpad.

But using adb isn't affected by MTP... I've never tried whatnot your doing BUT unless something is wrong with your cable or PC drivers.... adb commands like push, pull and install should work just fine if you have them allowed under Developer options

[Q] USB and ADB not working on 10.1.3-RC2

Yesterday I flashed cm-10.1.3-RC2 over a relatively recent nightly on my nook HD+, wiped cache and dalvik-cache and rebooted and all seems well except I can't access the nook from my Windows 7 laptop over USB.
When the USB cable is connected between the nook and my laptop, the laptop continually beeps like it does when you plug or unplug the USB even though the cable is plugged in all the time and windows explorer flashes a window open and immediately it closes. I tried setting USB to both MTP and PTP on the nook and neither works.
ADB doesn't work either - it says device not found.
On the nook I still have notifications that USB is connected and ADB is enabled even though the cable has been disconnected all night.
Anyone else experienced this?
Thanks!

You need to uncheck Android Debugging in developers options. But first you need to activate developer options. Go to settings, about tablet and tap the build number several times. Then you can access developer options in settings.

That fixed not being able to access the nook over USB but ADB still doesn't work. The message I get is:
C:\sdk\platform-tools>adb.exe shell
error: device not found
it used to work before I flashed RC2
Thanks!

ADB is not easy to set up for windows. Just because it worked before does not mean it will work later. The device id keeps changing in your device driver. The solution is to not use ADB over USB, use wifi. There is a setting in developer options (ADB over network) that is much easier than USB. Just type adb connect and the IP address shown in the developer options. Much easier.

Thanks. I was able to accomplish what I needed to using adb over IP

File/Photo Recovery Mission - Phone dropped - USB debugging off

hello
dropped my N6 on to a marble floor, the screen is black and touch is not responding. the phone seems to be working otherwise. usb debugging is off, the phone is fully stock (stock recovery, bootloader is locked, encryption is the marshmellow default, phone is not rooted). There is no lockscreen pin or pattern, just the standard slide to unlock. photos are not auto-backed up online, so I need access to the phone itself.
when I plug the phone into my computer, I cannot file explore it because I need to enable a prompt on the phone to MTP instead of charge only. as USB debug if off I cannot use ADP PULL / SDCARD.
I have two ideas:
1) use Wug's nexus root toolkit and do something there like put TWRP on, and then use TWRP to avoid the USB debug being off. I'm not sure on the details of this though! Any guide on the steps here? the power and volume hardware keys work, so in theory I can get into recovery with the right steps.
2) get a micro-usb hub, and plug in a wired mouse as well as connect to my computer, then blindly click about hoping that I enable MTP or USB debugging. I can then either copy files off in windows explorer or use Vysor to control the phone over ADB and email files etc as needed. Would this work? I don't have a hub so would need to spend £5-10 buying one
Many thanks in advance for any help!

Option 1 won't work because the bootloader is locked. You'll have to try option 2.

Nexus 6 on 7.1.1 won't retain PTP USB mode across reboots - no ADB connection

Does anyone know why PTP mode would not be retained across a reboot? It seems to revert to MTP when rebooting into either the bootloader menu or into regular user mode.
I am trying to unlock the bootloader on my Nexus 6 running the latest build N6F27C of 7.1.1 that was sideloaded over 7.0 using ADB from my Mac. Now I'd like to start again and perform a clean flash of the 7.1.1 using ADB.
In normal user mode I can enable USB debugging in Developer Options and when PTP USB mode is selected then ADB will list my device just fine, I can trigger a reboot, etc.
However, after rebooting into the bootloader menu ADB shows that it has lost connection with my device, even though the screen shows that USB is connected. The ADB device list is empty.
On subsequent reboot into user mode I can see that USB debugging mode is still on but PTP connection mode has reverted to MTP, which (at least on a Mac) can account for ADB's lost USB connection to the device.
ADB debugging in PTP mode has worked fine for me in the past, but the phone now has been through several factory resets and restores from Google's backups, plus it is on 7.1.1.

Nokia 4.2 ADB debug and mtp

Hi, on my Nokia 4.2 phone I've enabled adb debug mode, but when I set USB transfer mode to mtp, the adb connection gets disabled. Is there a way to have both features enabled?
Thank you
