Hi all,
Such devices like Xperia U,P.... iPhones,
and some other devices which have no
external storage but USB OTG supported,
can use SD card or pen drive with OTG.
There are many kind of OTG cables, but it
is very hard to carry an OTG cable & a card
reader all the time, so i am thinking of an
OTG with card reader in a very small (as
small as it can be) form which can be carried
all the time.
the card reader will b stored(may be fixed)
with the back cover(as shown in the pictures)
.
i am usuing very small card reader slot, thin
wire(like insulated copper coil wire), a tiny
siwtch(on/off).

As we know, in OTG pin 4 and 5 are
shorted so i am usuing a tiny switch, when i
switch on, the pin 4 & 5 are shorted & the
cable will work as OTG, & when i switch off
it will turn as a normal USB cable, so there
will be no Battery Drain.
i am trying to configure it ,but having
problem when soldering the wires with the
micro usb male port.
The connections are so tiny, so it is very
hard to make it alone, i tested it in a bit
large form & it workes, but in small size as
shown in figure it becomes very hard to make
it ,,,,,,,
i am requesting you all to try it & make it
by yourself,
if we can make it personally i think one day
such cables will b available in market in very
stable form for all usurs.

Hi folks,
I hope this helps someone out there. I didn't have a USB A female to USB micro A male On-The-Go (OTG) cable, they are rather rare. So I made my own. I have it plugged in right now and both my keyboard and mouse (Logitech K350) communicate to the bluetooth dongle, which is plugged into this cable, and into the Q and working fine.
This is how to make one:
Cut the female USB A female end off a USB extension cord
Cut the male USB micro A end off a USB micro extension cord (the micro A looks squarish, the micro B looks trapezoidal. Both will fit in the Q's receptacle. This should be possible to do with a micro B end too, but I didn't try it.
Solder the wires together, matching color to color. Tape up the wires so they don't touch.
Now you'll notice the "big" USB has four pins and the micro USB has five pins. And you soldered four wires. So what about that fifth pin? Open up the micro A connector. Most of them are fused shut but you can usually slit it on either side with a knife and open it like a clam shell. Find the fifth pin (it'll be the only one not connected to anything). Short that pin to the ground pin using a bit of wire or solder. You can figure out which one is the ground pin either by looking at the wire color (should be black) or consulting a micro USB pinout diagram.
Glue the clamshell back together again.
Plug in your keyboard and/or mouse (dongle or otherwise) and it should work! Does for me! Not only the basic keyboard/mouse functions but also many of the special keys, like the special "play" / "pause" / etc buttons at the top. Esc is back.

Well then...
I was wondering if experts on this forum can help clarify these questions.
The tablet Z has a rectangular shaped micro usb receptacle which is the microusb A/B type as I understand it. Although the normal popular micro usb B type connector which is supplied with the tablet Will fit in there, it is kind of loose, being able to move a little bit. Whereas the A type connector which is usually found on the OTG cables is a perfect fit and does not move around..
So, why is it that even Sony does not supply a cable which perfectly fit the receptacle?
If I use an otg cable to charge somehow (by making another cable from otg cable for eg or using otg with a normal usb male to male cable), since 5 pins are used in the otg connector will it in any way damage the tablet? (physically or otherwise..)

Hello
Can someone tell me the exact type of USB connector is on the Samsung Galaxy View. Then manual only says
it's a USB connector V2.
I've ordered the device but have not received it yet. But trying to determine if the connector is USB v2 or micro USB connector?
Want to plug in an ethernet adapter.
Thanks in advance
JRS
The port is micro-USB (not to be confused with mini-USB). Although most stores don't mention it, most reviews do. The Gizmodo review even has a close-up picture: https://gizmodo.com/samsung-galaxy-view-review-i-love-this-magical-slab-of-1740835366
i would recommend grabbing a micro usb "cable" OTA adapter - you can utilize it for all usb storage, upgrades, etc, etc.... they make a hard snap in adapter but use caution on them as for as easy as they snap in , they also snap out breaking your port with it. The cable adapters are way more flexible and with the tablet being so large in the first place it really doesn't make a difference if it's dangling on the side.
I tried to hook up a game controller via the OTG adapter and it appears to not send any power out from it. Even with a USB thumb drive and other USB C adapters, nothing seems to work. Has anyone else noticed this? You can transfer data via the cable just fine, but I find it strange it doesn't send any power through the plug.
Have you tried connecting it the other way round?

I noticed the same thing. I believe it's because once it comes out the other side with the 5-pin adapter, it is then reduced to the old micro-usb specification, which uses 5 wires. True USB-C connection has like 20 or 24 pins. I was able to get a couple very basic OTG of things to work, like a mouse and a thumb drive. BUT HERE IS THE CATCH - The mag connector has 5 pins, reduced from 20-some on the C connection.. so true USB-C connection is no longer possible once you get on the other side of the connector. So the trick is to NOT use a USB-C OTG when it's in the case with magnetic adapter. You must use a Micro USB OTG with a Micro-to-C adapter attached to that. Even so, not everything worked just by sticking on the Micro-to-C adapter.. Mouse and a thumb drive worked, but my ethernet adapter and VGA/HML/HDMI adapters did not. Out of the case, I can use my USB-C to HDMI cable to display on my TV. But same cord does not work with the magnetic adapter with the case. It is simply not possible because the reduction of contact pins from phone to case to magnet.. One more thing to consider, if you're trying to do anything other than charging, make sure the magnet is on the right way.. there's a little logo it should be in the front.
If I can come across a spare or broken Dual Screen case, I'd be curious to take it apart and see if it would be possible to rig it up with a better plug for the case.. find which wires go to the workings of the DS and leave them intact, but then try to replace the magnetic pins with a female C plug that has all the contacts intact still..

Thank you @Seymour_Asses ! I saw here https://twitter.com/konic0s/status/1202966945693220865 that LG G8X supports USB-C to HDMI adapters but I didn't know if it also worked with the Dual Screen case but now I know it doesn't, thanks for the information, very helpful ! :good:
BTW I think that when you connect the Dual Screen case to the G8X it uses the dedicated USB-C high speed pins of the G8X for video-out so these pins are not available anymore for other HDMI out, I'm not sure about it and don't have any proofs but it seems you are right about not enough pins on the mag connector.
If i remember correctly, the manual states that most USB-C functions wont work though the dual screen case. I think there was some speculation that its due to most of that bandwidth being used for the second screen.
Quite simple: the Mag USB-C adapter is for charging only. It drives me mad as i have a professional USB-C headphone that I use for conferencing.
But I understand the reason: when in dual screen, the USB-C data connection is in use dor the second screen, enabling the USB-C connection beyond that requires a hub to be built in the case "before" the DS connection (so it wont work building it in the dongle itself).
I wish LG went with a Pogo connector on the bottom or on the side to activate the DS case. This would have made the chin slimmer and freed up the USB-C port.
Anyway, it is what it is now, and i will not trade my LG G8x DS for anything at the moment... Until maybe that Surface Duo phone for which I might need to sell a vital organ ?
