In my YT9216BJ Head unit there are two USB ports. Both of these ports were working fine and I could attached two different USB Disks. Since last few days one USB port is not responding. If I connect mobile phone through this port instead of a USB drive it start charging mobile battery, which mean this port have some voltage.
What could be possibilities to investigate this 2nd USB port ? Any app for diagnosis of the issue ? Could it be issue with connectors in the back of the headhunt ? USB cable ? or Some hardware failure inside the headhunt. Any possibility to fix this issue ?
Could be a bad connection or failed cable. I would first double check usb settings in Factory settings and maybe do a reset and see if that helps first. Then could pull out the unit and swap the cables with eachother to test

Hey, i just received my usb 3 cable (my s5 came with usb2...) and i think i got a fake one...
I bought it from here: ebay.com/itm/291161252997?var=590311054317&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Now the problem is, when i plug cable in it USB options there is no "Media device (USB 3.0)" option... Which if i am not mistaken should appear?
I don't understand... 190 cables sold and no one is complaining... Maybe i am doing something wrong?
You might connect it to a USB 3.0 Port, are you sure that you connected it in 3.0 port?

Yes i am sure i connected to usb 3.0 port. I just found out that my external monitor connected via usb using same type cable as i ordered (but it's very short cable) and it is usb 3.0. Tried connecting with it and now i can see that option. So i guess that means i got fake cable...

Based from my experience, buying micro USB charging/data cable for Samsung is tricky since the wiring may not be the same as the normal USB cable. There should be 5 pins on the micro end, but sometimes there are just 4. But Samsung uses only 4 pins that might have been rewired. I'm not sure whether only Samsung does this or the same can be said of the other brands, but they may be the cause why there are microusb cables being sold that does only charging and no data function, and vice versa. And sometimes the pins may not be protruding out enough to make contact with the phone's charging pins.
I hope this helps.
You should try plugging in another USB 3.0 device such as a USB stick to determine whether the fault lies within your computer or the eBay cable!
Hi folks!
I want to connect an android device (it has usb slots... i can plug there 3g dongles, keyboards, wifi etc) with my computer to try to establish an adb session.
Is that possible like that (usb male - male)? Do i have to solder a custom cable - and how would he wiring be to force the android into "client mode"?
Any help is highly appreciated!

to wiring an usb cable is not so hard. normally you only need to solder the same coloured wire together, red to red, white to white, green to green and black to black. but there are already male to male cable to buy.

what does your android device have for an usb? is it micro usb or standard (type a)?
if you have a micro usb port so use an usb data cable, most of the charging cable does have data transfer support.
your computer even needs a driver for your android device to get working the adb.
good luck!
ps. on ytube there a lot vids how to... only search and destroy ( your android)

Hi! Thanks for your help! Its a type A jack on that device just like on the computer. Adbd daemon is on the device running but my windows machine cannot detect an usb device with direct soldered pins (or a bought cable which seems to have the same wiring)
I read about possible collitions when both devices of an usb connection are in host mode and that maybe pullup resistors on the data lines are needed - but i didnt fully understand that part. (Its different to the pin shortening of an usb otg wiring which can be found thousand times on google *G*)
can u describe exactly which cable u have used? and sometime the colors of the cable are not correct e.g. red is not +. those are build by chinese manufactures for cheaps goods. so u have even to measure the cable with a voltmeter.
and describe what happen when u plug the cable in the pc. normally windows is always running as main and android as slave.
as you describe u have an usb a type so i guess your android version is minimum 4.x and is already automatically on host status because you said u can put in a 3g dongle...so u have to go to the android command change from inside. i dont know much about linux programming so have to ask a developer. i only do developing hardwares not softwares, sorry for that.
what is your android device? with a datasheet is it better to solve your problem.
Hi KindsKoPP!
Thanks for your help and interest!
Basically I tested with a 1 to 1 wired cable I soldered by cutting 2 usb cables. I double checked colors (measured their output when connected to the computer) and found them ok. Then I connected them 1 to 1 (red-red, black-black, green-green, white-white).
But no usb device showing up or asking for drivers...
I know that adbd is running on the target device.
I pulled up some info here: http://www.valki.com/2014/12/04/analyse-av7/
I am still hoping that those usb devices who are in a double role (like our phones too with their usb otg host mode and client mode for mtp, adb...) are triggerable externally by using special soldered cables (resistors?) ... like "when resistor xy is on D+ -> go to client mode"?
USB connection problem
No change in device manager happened even in fastboot mod, it's only changing, I test a lot of way for solving but no ways help me, if there is a solution, tell me. Thanks
Sounds like the USB port needs to be replaced on the phone.

I'm sorry Guy's, but I have to go for a monthly, but thread is open for your comment and solution!
There is an internal ribbon cable that connects the USB port to the motherboard.
I believe this internal cable needs to be replaced if trying different computers, USB cables, and USB 2.0 ports doesn't solve the problem.
I fix my phone problem, a repairman change my micro USB socket.
Hi. Last month I forgot my charger somewhere and I endded up using another one that didn´t work fine.
my problem is that the usb conector only work for charging (turbo charging work too) but not when I try to connect it in my pc.
I already use different cables so I think I should change the usb port, but it could be something else? maybe the board is broken?

If you tried to connect your USB cable directly to the back ports of your PC, i mean, the motherboard USB ports (not the front ones), and tried in differents PC's too, looks like your charging port has been damaged.
Something exactly as you described happened to me in the Nexus 5, but in that case, just had to change a flex cable that contained the charging port.
Anyway, it's a very cheap part, and it's pretty common that the welding of the USB port get broken. You will have to send your device to a mobile repairs shop, or change the charging port by yourself (only if you have some knowledge using welding stations).
I recommend the first option because it's the most common break on a phone, and these guys in the shop must be very accustomed to repair this (it's not very expensive either).
try any other phone's data cable! :?
I've tried another cable and my computer connects but says the file is empty. I tried my old phone and I can see files. So I think there must be a setting on my Moto 4 that I need to change. When I drag the status line down I don't see USB or connect to camera.

Hmm, when you pull the notification shade down, do you see a notification about 'USB Charging this device' when your device is connected? If so, then what happens when you tap that notification - do you see a pop-up like in the linked screenshot? If so, tap the Transfer Files option in that pop-up and your device should re-connect and show the internal storage of your device.
If your device is in USB charging mode, it seems normal to not show files (as a security measure?).
Hi All,
In the car stereo 8227l demo, both the usb ports are not working/ no response by using usb check app it shows thar usb ports are not enable, can any one help me in enabling the port
There are some USB settings in Developer Options that you might need to configure.
Sure, I enabled and made usb debugging. Also enabled other usb settings like usb audio enable but no luck

Has anyone found anything
I have the same problem, and it's driving me insane!
HU doesn't recognise my phone when I plug it in via USB. it only charges my phone. I've changed USB modes and enabled debugging but no success.
In 8888 menu / others - check usb version.

I finally got mine to work. it turns out the port on my phone was dirty. so after cleaning it out thoroughly with alcohol wipes and contact cleaner with a thin safety pin straightened out and bent into a U shape, I plugged it in and voila... notification pops up saying device connected
on my device, it was necessary to activate the Welink option in the Factory Settings Menu, to reactivate the usb ports
