OK, I know this is a very basic question, but with Google I can't find a specific answer.
When I go to connect my S4 to my computer via a USB hub, the computer doesn't see the phone at all. However, if I disconnect the hub from the computer and plug the S4 directly into the same USB port on my computer that the hub was connected to, it works (i.e. the computer sees the phone).
I know the first thought is that the hub is bad, but I can plug in a thumb drive to the USB hub and the computer sees it fine.
FWIW - it's not an externally powered USB hub - it only plugs into the USB port on the back of my computer. I don't know if that has anything to do with it (although I still wouldn't understand why everything works fine going direct from the phone to the USB port on my computer).
Thanks in advance...

Hi
I just wonder it is any chance to connect two host to one android device?
I would like to connect 1x portable HDD and 1x SD Card reader to my Samsung Galaxy Note to get connection between hdd and sd card reader, just to simple transfer files between them. I already tryed connect them together via a SD Card reader with bultin host adapter via a USB socket in this device, but when I plugin a HDD to already connected sd card reader host I get an error and only a second connected device is working, so it looks like only one storage device can work in a same time. So maybe it is possible to apply some spllitter before two hosts and connect each device to different host adapter?
an usb hub, maybe?
If I understand you correctly, the problem is there can only be one host in any USB connection system.
In this case that host device should be your Galaxy Note.
You will have to be using an OTG cable and a USB hub.
The most I've ever connected at one time to my little device
was a card reader, a flash drive, 2 keyboards, a mouse, an audio adapter and a GPS.
I already have a OTG cable and the usb hub. But only one storage device at a time can be recognized by galaxy. When I plugin another one, the one already connected is automatically switched off and galaxy showing an error
I found the solution, the problem was with insufficient power, so I rebuild a otg cable a little bit to give it a +5V, and another +5V to a portable HDD and now I have exactlly what I need... a simple USB OTG BRIDGE fully controlled by GALAXY NOTE. I was need this to use a portable HDD as a photo bank (copy all of files from sd card to hdd in a travel). Thanks for your posts anyway.
Hi,
i have a Cube U23GT tablet. It supports OTG. The tablet can be charged only trough DC in with an adaptor, so not trough usb port. I have an OTG cable, and if i plug with that a mouse in, or keyboard, it works perfectly. I saw on youtube some videos where people connected mouse and keyboard at the same time to their tablets, for example: youtube.com/watch?v=benblX95ORM
So as i saw this video i thinked: all i need is an USB HUB, i bought one: logilink.eu/showproduct/UA0138.htm?seticlanguage=en
I plugged the HUB in trough OTG and the result was: the LED of the hub lights are on, but then, when i try to plug the mouse OR (not just "AND") the keyboard, it wont work. The infra of the mouse is lights too but the tablet dont detect it, i cant use it.
So can you tell me what can be the problem? Its not a powered HUB i know, but on the videos that i saw (for example what i linked here) arent powered hubs too, and works.
If you can, please help me, thanks!
Has anyone tried or know if i can connect usb port replicator to an android phone with OTG cable.
The idea s can i essentially connect 2 monitors to an android device and then use them with VNC to connect to actual computers therefore being able to use the tablet/phone as a very portable computer.
Regards
just tried it with an otg adapter on my note 3 and a lenovo port replicator.
usb ports work fine (keyboard, mouse etc) but I cannot get the monitor to light up...
Hi all, I have a MK809III tv stick with Android 4.4.2 running. I use it as a mini PC with a LCD screen. I have attached to its USB OTG ports a quadrate 2.0 4 ports USB HUB (google for this and you can see it) , and connected to it, a PS/2 keyboard (using an usbtoPs2 adapter), an usb mouse, a usb ethernet dongle, and a usb sound card dongle. When I use this combo, all works fine, the mouse can drag and select, also wheel works, the keyboard works fine, the ethernet run smooth, and the sound works as player and mic recorder, the only thing not works is to reboot the tv stick, and launch android again (with other MK89III tv stick this also works flawlessly), to get this, I must to unplug RJ45 or usb ethernet. But this last question is not my main problem. The main problem is that I can not make the combo work anyway if I change usb hub model, If I use a 2.0 usb square hub (no name brand) with a little blue led installed, all works fine, but using other hub (I have tested two others), thare is no way to work. The main situation is that the hub stops work, and all item connected not works at all. But commonly, mouse works with a bad behaviour in button response, usb sound disconnects suddenly, or usb ethernet lagg or not works at all. My question is about this behaviour with usb hubs, if there is a special requirements in hardware to match an usb hub with this kind of android devices, or if thare are some drivers that can solve this.
Thank in advance.
Solved
I have solved the two main problems in order to use my MK809III RK3188 as a mini pc with usb hub and rj45 ethernet. The hub must to be a chip on board one, no an all-in-one glued ultra-cheap type, this is a mark of better quality and response, then you can conect keyboard/mouse, usb or ps2 with usb converters, usb sound, and usb pendrives. The ethernet must be an ASIX AX88772C, this a true usb ethernet 100mbps (7MB/s real) device, since I use it there is no lag, no boot errors, no delays or shorts in Tx/Rx. That´s all.
I've been trying to find information about this on the web but I've failed to do so.
I bought a Kingston Micro duo USB C 3.0 and it worked a couple of times (I had to manually change to MTP) using the USB C connector straight on my S9+.
I've been trying to get it working again on my phone with no luck. Everytime I connect the USB C end on my phone, it will show on the notification tray "Usb charging device" and "USB connector connected", this last one will disappear in a matter of seconds.
I've set the default to be MTP using Developer Options and even select MTP for the device once it connects, but it just reverts its status.
I know for a fact the USB C end works because I can connect it to my computer (Windows and MacOS) and I've tried formatting it using a lot of different formats, still when I connect the USB C to the device it doesn't read it.
I managed to get the drive working using my USB C dongle (Which has 2 USB A 3.0, but no power passthrough) and connecting the USB A side to it and my phone recognized the drive instantly! So I formatted the drive using my phone, connected the USB C end on the device and it doesn't recognize it.
It seems it's just a bug on the Samsung device or something. I guess Samsung is moving towards USB C but they are not thinking on all the stuff you can connect.
I found this link https://us.community.samsung.com/t5...g-defaults-to-charge-other-device/td-p/183539 and this other https://forum.xda-developers.com/galaxy-note-8/help/note-8-usb-otg-t3680207 but so far no solution.
Edit:
I just tested my drive with an S8 and it worked without issues (the USB C end) and was able to test it on another S9's and they don't recognize it.
Mine works without issue. Not sure what's happening with yours sadly. Edit - mine's the Micro Duo 3C, but I can't imagine there'd be much difference.
Same here. Today I had hard times getting to work my USB stick and a default dongle. Every time I inserted the dongle the notification goes "USB charging device" and changing to "transfer files" doesn't change anything. Playing a bit made a 32gb stick visible in a file manager (namely x-plore) and I was able to transfer files to it. But no PC recognizes the stick so far...
