[Q] Quick Usb question - Acer Iconia A700 and A510

OK so here is my problem: every time I connect a USB via the micro USB port the device doesn't detect the USB. However sometimes if i am lucky I only need to twist the cable and it works shortly. Probably the cable is destroyed, anyone know if I need exactly this cable or if I could also use a normal micro USB adapter cable. Thank you.

Well, I'm a bit confused, as the 70x has actually 2 cables.
1. The USB cable that connects to a PC
2. The USB dongle adapter that has a full size USB connector (female) for connecting flash sticks for example.
Regardless, as in number 1, you can't use just any micro USB cable, like the one that comes with a camera for example. You might, but then again, the data connections may be wrong. Best thing is to try. Typically I use my HTC cable. Regardless, you won't damage anything by trying.
As in number 2, well, it may be hit and miss if you get a generic one. The + and - pin layout should be the same, but the data might be different. The only way is to check.
When you twist your cable, make sure it's not actually twisting the connector (micro). This may give false readings, when in fact it could be a damaged micro USB port on the Tab. So check it good.

ok thanx. found a working cable.

[Q] Asus Proprietary plug to USB converter? or anthing similar out there?

I was wondering if there is any such device / cord which would convert the Asus proprietary plug on the transformer to a USB cord or something so I could plug in different things without having to buy the keyboard....
Yes it does exist:http://www.asus.com/Peripherals_Accessories/Eee_Pad_Accessories/External_USB_Adapter/
Could you charge the tablet with a regular USB cable using that adapter?
Only when in deep sleep or turned off - but it charges.

No because the USB adapter linked only outputs 5v on the USB port, its not an input.
The USB socket is the wrong type for normal USB cables used for charging, but even a USB-A to USB-A adapter wont allow charging and may even destroy the USB adapter (well, it might not, but I certanly wouldnt want to try it!)
That is sort of what i was afraid of. I was hoping that since I can use the propietary cable, I would be able to switch to a longer cable with the help of the adapter.

Just attach an usb3.0 cable to the propietary cable. Then you have a longer cable.
I'am using this with the tablet and charger.
It has to be USB 3.0 cable? Dang, I actually do have an older extension cable somewhere (forgot all about it until I read your post) but it is pre-3.0, but hey, if i find it I will at least give it a try, not like something would brake, right? Right??
hmm...I had asked this in my thread, but no one has given me a straight answer. Looks like it wouldn't work even with Male A to Male A. I already bought one, so maybe I'll give it a try. Has anyone done so before?

Yes, it must be a usb 3.0 cable.
I have this one and can charge the tablet with this cable attached to the propietary cable and the asus charger
Just tried it again and it is now charging.
That is cool, but I was hoping it would be in a "cord" form because imagine you would have that sticking out from your device, then on top of that you would have your usb plug sticking out as well...
Also, would this work with something like a wireless keyboard and mouse? (the wireless receiver is USB)...

[Q] External USB Adapter

I've heard that the External USB Adapter from ASUS is a notoriously difficult beast to locate. It's marketed to plug into a bare tablet and provide a Host USB connector. But, would it also work in the charging port of the keyboard dock giving a second Host USB port? (Yes, I know a hub would do this. But If one wants this device to connect USB storage to a bare tablet, would it also do double duty and work with the dock?)
It certainly sounds possible. Mostly because I think the internals of the keyboard dock are a hub already basically.
One usb going to the card reader, one going to the usb port, one to the keyboard function, and another as a passthrough to the proprietary data port.
So by using the usb adapter you are just converting the otherwise unused data port into another usb port.
since there both 40 pin connecters i imagine that would work

That is also my assumption, but we all know what assuming does. All depends if all the signals are passed through, and if there are any lag or transmission line issues.
Has anyone tried this to verify if it does or does not work?

[Q] usb otg cable doesn`t work

I had my 7.7 for some time and about 2 days ago i've bought a cheap chinese usb otg cable from some shoup around here. I thought it would be as simple as pluging it in and connecting some usb stick like i've done with justabout all usb otg stuff i previously owned. But it doesn`t do anything. I`ve tried other usb devices, the tab simply doesn`t power them at all. I`ve also disasembled the cable and measure it, everything is fine. I`m on stock ics 4.04, also tried a couple of kernels, it just doesn`t work.
Has anyone encountered such a problem.? Damn weird....

I have an original cable but also bought an after market one that verizon had made available for their version of the 7.7
I bought it here:

errrr....I think I misread your issue and specific item...
sorry!
Still great though!
The usb otg cable is just a plain simple usb cable with a 20kilo ohm resistor placed between 2 pins on the galaxy tab 30pin connector. That's about all the things inside the actual cable. When you plug it in, the tablet should figure out that the 20k resistor made contact with the pins and an accesory was connected. Mine doesn't. The cable is fine, i think there's something wrong with the tablet. Doesn't it supossed to power on whatever you insert on that usb port? Because i can't get those 5v on the port.
I don't know if it's a software or hardware problem....

what file system is your USB Stick using? try formatting the stick to FAT32 and see if its a file system issue
have you tried using another OTG cable? I'm also using a china knock off bought for 4 bucks, running stock ICS and it detects most of the thumb drives I attached to it
thanks for the replies but the situation is kind of different in my case.
In order for the tablet to read what kind of filesystem you have on a usb mass storage device (stick, hdd, whatever) it must first power it on and then attempt to access it. In my case, it simply doesn't power on. So, it doesn't matter what kind of file format it has. Also, if i plug a mouse/keyboard, it won't work either.
I thought that maybe it's a broken wire inside the connector, so i took it apart and measured each pin. The otg adapter is fine, it should do the job. I've also tested on another samsung tab and it worked straight away. It seems there's something wrong with my tab. However, other then this, the 30 pin port on the tab itself seems to be working fine.

Split cable for charging and OTG

I am trying to charge my Nexus 6P while simultaneously casting a streaming video from a USB drive to a Chromecast using a USB keyboard and mouse (Basically a computer replacement scenario). I have purchased the Cynergy 3 Port Ethernet Hub USB C with USB C connector and everything works independently but I can not seem to get it to simultaneously charge and read the USB port data. When the hub is inserted into the Nexus 6P the phone asks me to choose between 5 USB scenarios (see attached picture). When I pick “Charging” the USB ports stop working and when I unplug the power supply and then plug it back in the phone defaults to “Power supply” and the phone does not charge but the USB ports work along with the items connected to them. So I wonder if simultaneous charging and data is possible with the USB C connector on the Nexus 6P? I have read elsewhere in this forum that it may not be allowed in the USB standard but can’t find any confirmation of this. Has anyone found a cable/hub that can do this or is this not possible due to the USB C connector limitation?
You might want to try something like this.

Why tell him to waste money on something that isn't going to work? The 6P doesn't support USB PD so this isn't possible.
i think you need to do some mad hacks in the kernel to get otg and charging at once (i think they did it on the oneplus 1 and possibly on the 2nd gen n7 so maybe google those for what it needs to be done?) i tried various resistors to the sense pin on the micro usb z4 which ended up not working but i have no idea how the usb c is wired up. Good luck with it anyway

Is there a way to turn usb-c to usb-c phone charger cord into an otg cable?

Anyone tried it? I searched anywhere, but no results

Just try it and see if it works. Some devices could work while others would need a dedicated OTG cable
Thx fydtyh. I will update later

It depends on whether the phone is used as client or as host. If the phone is to be used as a client, normal USB cable is used. If the phone is to be used as host, a OTG cable is used. It is a matter of pinout order.

You can convert the USB C cable into a OTG cable by changing the pinout order as indicated in the following discussion. You will need an adapter to convert one USB C end into USB A.
How different is a normal usb cable from OTG usb cable?
Answer (1 of 8): Hey, So USB OTG cable is used to connect to a device (say your phone, tablet) when you want to use that device (say your phone tablet) as a host. So imagine you want to use a mouse with your android tablet, then you can use the OTG cable as shown in the figure below Major dif...

I know the diagrams show microUSB instead of USB C but the pinout order should still be the same for microUSB and USB C.
