hi, i hve a xoom2, i bought it yesterday; but wht ive noticed is tht the microusb port dont hold well my usb flash ( fat32+16gb), i can charge my tablet but not directly when i plug it in the tablet, i have to pull the edge of the charger up while its in the micros usb port of the tablet so it can charge.
and when i connect it to my laptop, also ihve to move arround the cable data in the microusb port of the tablet .
its a hardware problem? can i replace the microusb port my self? or only moto can do tht?
thkssssssss a lottttttttttttt

Hello, we all know that there are USB OTG Cables with extra power plug (Y cable) but those are supposed to power external device like HDD, DVD, or anything what consumes more power than our android device can handle.
But my question is: is there any USB OTG cable with additional power plug but for simultaneous tablet / phone charging while USB stick is used?
I want to watch something long (i.e. TV Show series) from USB stick via OTG cable but I cannot simultaneously charge my tablet, so if it take too long my tablet will be out of power before I stop watching.

That means I have to add a resistor only to usb connector or just need a different kernel, or both?
On the native firmware say that this support function is disabled. Personally, I use this CivZ-FLEX-ЛУЧ-REV3.6.2 + SphereXtreme, where works flawlessly with OTG + charging resistor 64.9 K.
I call BS!!!!
I have a stock firmware, and have been using all kinds of USB cables. Found the best are made from Sony/Ericson and Blackberry. Once you have a quality cable your charging issues will go away.
Right now I am using a 7 foot cable that is from a Sony. No charging issues and works perfectly.
Lately I found another MHL cable 2hich is called HDMI to Micro HDMI, and that micro HDMI plug looks exactly like micro USB. Will such cable work with Note 8 properly without additional power?
The version of MHL our device supports requires a power source external to the tablet. That means the adapter itself needs to provide the power (battery or power adapter) or can pull enough off the HDMI cable, which is usually not enough juice to run the connection.
MicroHDMI and MicroUSB are also not physically compatible (won't fit the same port and different pin outs) even if they look so much a like. MHL typically uses MicroUSB at one end and full sized HDMI at the other.

This is correct u need to put a 63-65 k resistor between ground and Id pin(pin 4 &5) on USB connector. Doesn't work on civatos 4.4.2 as of now. USB host works fine with regular USB host cable but no charging when u use a y cable. I use civatos 4.2.2 kernel also. Works on yyks note 2 4.3 port also..
I have test multiple times. I use a USB dac in car and need charging and USB host.
what resistor should i use on my sghi257m samsung galaxy s4 mini otg usb cable?
on my dads galaxy s5 Active it shows message that says: Do you wanna enable power sharing
is that OTG? on my S4mini nothing pops up
I know this thread is really old but i want to use a USB DAC so need at cable with a resistor as mentioned above but What ROM should I use now?? also is there anywhere I can buy a cable with resistor in it or do i have to do it myself?
Does the Note 4 support ACA (Accessory Charging Adapter) to be able to charge the phone at the same time as using a usb OTG adapter?
I want to be able to use a USB DAC and charge the phone at the same time. Is this possible?
It's a very good question. I am curious about it as well.
I have 2 pieces OTG "Y" cable. 1 of them can to charge my phone but the phone can not recognize the usb flash drive. The other can not charge the phone but the phone can recognize the usb flash drive. I need a mixed cable from this 2 )
I need a quality OTG cable, any recommendations?
[Q] I lost my current phone usb cable , using old phone's usb cable to charge my phone now. Is it safe to do so?
Will it cause any damage to my phone in long term? Thanks.
The correct is to use your original usb cable, I have a Xperia ZL and my pc don't recognize it without the original Sony usb cable. But this isn't your problem, so you can use your old usb cable to charge your device with no problems
hI everyone in regard to otg using Usb and charging tablet at same time, I have a fusion5 tablet and a usb hub the kind with 3 usb hubs and a power in with a micro usb male plug. and a switch for otg or charge. Ive tried using a potentiometer to find the magic resistor value between pin 4 (the id ) and pin 5 ground of the micro plug.
(thought i had it at one point but not sure) as could play a avi file while charging) However now most of the timee either accesses the usb or charges, I can get it to do both , but stops charging after 8 seconds.
Anybody happen to know if a specific resistance value works for both charging and otg.
I have seen another schematic but havent tried it.
It doesn't sound like the micro usb otg cable to me. I built one without a resistor and mine works just fine. Have a look at your usb settings. Some devices require you select your choice: usb otg or charging.

Thanks How do I look at my usb settings?. I think I may not have the proper resistor setting as will currently provide power to usb and charge at same time for a few seconds then stops charging.. I turn resistance up it will charge , turn it down and will allow access to usb.. i think have to find that magic number inbetween.

Depending on which phone and version of Android you have, the most recent versions of Android have the USB settings under Developers Options.
The USB OTG charging works differently from phone to phone. Sometimes you must plug your charger cable and the USB device you want to connect to into the OTG cable prior to plugging the OTG cable into your phone. This way the phone detects charging and device.

Yes that is what I have been doing . In developer options under Usb default , no charge option there, only file transfer, USB tEThering, MID, PTP ,and o data transfer
I thanks. However i believe the default USB option is charge as thats what it is when i plug in USB to a powered cable.
. As I said jt works for A short time using USB and charging at same time with resistor between 45K and 68k
then either stops charging and continues usb or keeps charging but gives usb errrors or cant access usb but continues charging.

Update this works fine with unmodified USB hub or charge power and USB on my LG k32 phone but not on the fusion ta blet.
I have this usb a to usb c cable that comes with my buds 2 and whenever i try to use the cable to charge my phone by connecting it to my laptop, the charging speed is always way slower compared to when i use a usb c to c cable connected to my laptop.
is this normal or is something wrong with maybe the cable or the device being used?
*the laptop im using is a legion 5 (2021) and the port im using is the usb a 3.1 gen 1 port

Most USB A cables do not support Power Delivery (PD). You need a type C to C cable.
Just like @TheMystic said, not all USB-A to C supports PD. Furthermore, not all USB-C to C supports PD.
