I've seen numerous threads and posts about this here and on the Xperia forums regarding the E3. I'm not sure if its isolated handset faults or all of them so I'd like to know if it would be worth sending it for repair or accept and move on.
Never had any problems with the Logitech unified receiver, but usb OTG storage has always been unreliable. Nothing has changed with the 4.4.4 update and a full wipe.
When it doesn't want to work powering the usb stick with a Y type OTG cable or via a usb hub instantly cures it, but that's impractical on the go. Connecting a usb power meter shows the current surging from 6>13mAh before the error notification that the device is corrupt/safely remove message which begin to loop. It also seems to get confused that the OTG cable is a charger if the phone is allowed to hit 100% charged and this seems to be one of the things that tips the OTG Mass Storage class into the non-working cycle.

I bought a small micro - usb female adapter. When I plug it in, no matter what device i use it seems as those the xoom is not sending any power through it.
Ive tried
Camera
Charge Phone
usb mouse
usb wireless mouse
nothing is getting power.
Is there something i need to enable or do? Or has anyone esle has this issue? I am on 3.1....
You can not use a simple micro usb adapter cable, it has to be an OTG USB Host cable like the official Motorola camera connection kit that is now available. This is a bit expensive but readily available at your local Best Buy.
Take a look at some of the many posts on OTG cables and you can find info on cheaper cables that have been verified to work or on how to make your own.
you need a USB Host cable. Not just a regular sync cable. You can google for one or search the threads here where others have linked to confirmed working cables.
dang, thanks guys
I ordered one from ebay! hope it works
I have a question that applies here, I am on stock 3.1 Xoom WiFi/3G and just got my OTG cable, plug it in usb drive blinks like its working but where is it located on the Xoom? I've been looking around for it with Astro and File Explorer and I'm unable to find it... could someone tell me the path?

i believe stock 3.1 only supports MTP, hence no USB mass storage.
http://en.wikipedia.org/wiki/Media_Transfer_Protocol
I've heard many conflicting stories, I would like some sort of confirmation rather then speculation about what will/will not work with the Moto Xoom (Stock 3.1) Wifi/3g and an OTG cable because I've seen posts saying yes and no to USB, portable HD's etc etc. Can anyone even provide me with some informative links? Everything I've searched for has been less than informative.
So, stock 3.1 Xoom is an MTP device, that is true.
However, with latest series of Tiamat custom kernels by Bigrushdog (see Android Development section) the usbOTG has been enabled. If you have already rooted and installed the proper bootloader/Tiamat kernel, then in File Expert you will find the usbOTG folder on the root directory, same level as internal sdcard and data folders. If you go up a step in sdcard, you should see your external sdcard. Is this clear?
I have rooted, using the Tiamat 1.6, I have access to the sdcard now but I am still unable to access my usb drive (thumb drive). I have an OTG usb cable and when I go into the /OTGusb its empty. The drive blinks as if its initializing but then nothing.
On a side note, I have looked through both OTGusb folders, restarted the Xoom with the OTG and usb plugged in as suggested in another post and nothing I've tried has worked in locating the usb drive.

I've found that there are two factors which may be in play here...
1. When I connect a flash drive it takes a bit of time for the directory structure to parse... It does show up in the OTGusb directory.
2. I've found that anything larger than 8GB (I've seen it stated in the forums as well) does not work (of if it does it takes forever and a day to become available)
Hope it helps...
I have same problem here. whenever I try to connect the USB with Motorola connector, it doesn't appear anything in otgusb
I'm not sure I am going to get what I want at this time with the OTG cable. My goal is to be able to use the OTG cable to connect a USB thumb drive to so I can carry additional movies, documents, etc without completely consuming the main Xoom storage.
Can the OTGusb cable support this? Do I need to wait for yet another update?
TIA
Hello,
This is extremely slow to copy anything via USB to My Nexus S. The maximum speed is 3400Kb/s.
I have an original Samsung dock. I've experienced this speed with that dock and with an original Motorola Droid USB cable too. With the dock my device disconnect from the PC in every minutes, and my phone showing me the green android instead of the orange one.
During a copy, I've lost around 1GiB free space from the USB storage, b/c the phone was disconnected. Is this possible to take back this storage space?
How can I solve that speed issue? Please help me, and if I can provide you more information just ask me.
Thanks,
Montyx
make sure your computer USB is at least USB v2.0 port
some computer have mixed USB1 and USB2 ports
some even require a driver for the USB2 to become active at full speed
same goes for USB3 ports
Hi guys. Is there an app out there that makes it possible to connect an external USB flash drive or 2.5" drive to the shield tab via its USB port?
I'm pretty sure you just do, and you'll be good. Strangely I've never had any problems using an OTG USB drive with the Shield. That's what you'd be looking for, by the way... Am OTG cable.
One quick thing to note is, be prepared to need to power the hard drive. The tablet may not have enough juice to power a full hard drive. So if you plug it in and it isn't recognized, try a powered USB hub.
Secondly, make sure you have ES file explorer.
I use a WD ultra passport portable 1tb drive and a otg cable.
I just plug in, open ES file explorer an get what I need an unmount an disconnect.
You'll lose a few percent of battery potential as expected.

Thanks guys. I'm honestly shocked this actually works. I tried it with my WD passport laptop drive and low and behold it works flawlessly. With the research I did in the past with my HTC EVDO 3D, and reading all the comments on various messageboards, I really thought connecting USB HDDs to any Android device would not work. Does it work in this instance mainly because the device is a Shield Tablet? Or is it only because I'm rooted, and as a result any rooted Android device will allow USB HDDs to be used?
OTG and enough power
It just works if your (android) device has an On the Go (OTG) USB connector AND if it gives enough power to your (hard) drive. If there isn't enough power, you need a Y OTG cable and external power source. Many smartphones do not provide the 500mA at 5V they should provide, but tablets usually give enough from my experience.
The title was supposed to say C-C
As in the title really; When I plug the phone into my laptop (Lenovo ThinkPad L450) with a C-C cable, the following happens.
Some key points in trying to diagnose the issue:
Used three different C-C cables including the one that comes in the box
Tried a USB 3.0 A-C cable on the same laptop, works perfectly
Plugged a HTC 10 into the same port with the same cables, allows fast charging and 3.1 transfer rates
I have been into 'Developer Settings' and changed 'Select USB Configuration' to 'Charging',
Can anyone help, or is anyone experiencing a similar issue? I really don't want to have to RMA this.
for charging i cant really help but for data transfer try enabling usb debugging and getting the right drivers for the pixel 2. also connect as MTP for data transfer.
havent tried any of this myself as i dont need to transfer my files yet and theres no roms either but let me know if it works.
good luck!
I have kind of the same issue - while mine charges, it doesn't recognize the phone for MTP at all. Tried both the cable that came with the device, and the 5x cable I've been using since February. My husband's 5x is recognized, my Pixel 2 isn't. Have to use a USB-C to USB-A cable to do any data transfers.
This ticks me off, because I have 2 USB-C ports on my laptop. One that's a USB-C/Thunderbolt port (which always worked with the 5x), and the other that's just USC-C with USB 3.0 capability, which has my USB hub plugged into it. The hub won't work with the C/TB port, and now neither will the Pixel 2. So I either have to grab my C to A cable to load music and use ADB, or plug into the hub's port, losing my external keyboard, mouse, external HDD, printer, and Wacom tablet.
vido.ardes, is your C port Thunderbolt as well?

I posted my problem on the Google Product forums, and got this answer. It worked for me.

Hi all,
I just faced this issue. Connected my Pixel to my PC, no indication of connection either on PC or on Phone, except that the phone was charging. Even the file explorer on Windows 10 wasn't displaying Pixel as a connected device.
I found a solution, I hope it works for you all,
Go to Settings->Apps & notifications->App info->Tap 3 dots in top right corner->Tap 'Show system'.
Then find 'External storage' and 'Media storage' apps in the list and clear cache and data for both these apps. Restart your phone and wait 5-10 minutes before connecting the phone to your PC.
After connecting, the phone should now show 'USB connected for charging', as it did in Nougat. You can tap that notification and select file transfer."

These are the exact steps I did on the Pixel 2:
Settings>Apps & notifications>See all 125 apps>3 dot menu>Show System>Media Storage>Storage>Clear Data (this got the cache, as well)>Back>Back>External Storage>Storage>Clear Data.
Then I plugged it into the C/TB port, and the computer made the "USB Connected" noise, and "USB Debugging" came up in my phone's notifications (yes, I've enabled developer options and USB debugging there.) I'm then able to go into Settings>Connected Devices>USB and choose Transfer Files.
I just cleared the cache, not data for both and it worked.

Now that you can connect to your PC, is there any way I could get you or some other kind soul, to pull the system/framework folder and system/priv-app/SystemUIGoogle folder for me? The system.img files cannot be unpacked at this time. Every method tried gives "List index out of bounds" error.

Thanks for the advice, but unfortunately no change for me. I fear I may have to RMA this, which I really don't want to have to do.
I have found on my other devices, that if I reboot to recovery mode, my computer can then read the file folders in my device.
This appears to be an issue with the laptop, not the phone, as it works on another PC with a USB-C port
I got an Anker OTG hub. It works completely if I connect it to my laptop, however, if I try connecting it to my phone, my USB mouse+keyboard combo (wireless with a receiver) doesn't work. It works with other devices, including my laptop's USB C port, and my old phone's USB C port.
I did turn OTG on prior to connecting anything (I'd love (root) to know to keep it on at all times).
I already ensured they work on other computers through that OTG adaptor, and that a USB storage stick works on this phone through it. In addition to that, HDMI works too (the adaptor also has an HDMI port), and the USB C passthrough passes power successfully, as well. No warp charging, but that is to be expected and that's alright.
I have TWRP and everything. Is there a kernel mod I need? I'd be happy to do whatever's needed.
Maybe OnePlus needs some updates
Even i have latency issus with my midi keyboard
But not with op5t
