Just installed latest Lineage on my 2019 pro.
Only one USB port is working.
Wont read either of my 256gb usb memory sticks.
Is this normal

I'd kinda hoped most people wouldn't care too much about leaving that port in device mode. I personally have adb connected perpetually. But then again, I'm not most people. It's on the todo/research list now.
Edit: Fwiw, usb hubs do work, but I know that's not the ideal solution

After spending most of an afternoon trying to figure out how to get Heimdall to recognize my new phone ("Samsung USB Composite Device" was not turning up on the list of devices to install the driver for -- just 'Unrecognized device' turning up in device manager), I just came to the realization that I had it plugged in to my USB3 port. Switching to a USB2 port fixed everything.
Strange thing is, the rest of the phone works fine on the USB3 port -- just download mode won't connect on it.
Putting this here in the hopes anyone else struggling with this will spot it and give it a go.
@ OP
download mode works fine with USB3 + windows 7 64 bit.
USB 3 works and USB standard is backwards compatible anyway .
Was your USB port a mainboard port as SGS2 needs one not the often lower output on other ports .

Hello.
I decided to try and make a DIY OTG usb cable for my atrix, followed one of the many guides on the web.
How ever, Nothing seem to happen when I plug something to the phone.
I tried keyboards, mice, pen tablets, thumb drives, but nothing happens.
Also when I connect the phone to my laptop with the same cable, nothing happens either. (From reading around I think that should be expected)
Using another cable the laptop recognize the phone and all is well so I didn't fry the port.
Something else that might be worth mentioning, I use a male micro usb to male regular usb and a converter to female at the end of that one.
I tried it with both latest CM7 nightly and Jokers 0.6.9.1 CM9, both on their stock kernels.
So am I forgetting / missing something or should I take apart the cable again and check what's wrong?
Edit:
Toke apart the cable, removed the connection between pin4 and pin5 and the cable worked as a normal cable again.
Can't think of a reason why this isn't working.
normal OTG cables don't work with atrix,
I have read somewhere that you need to power the otg cable with external power source, you can mod a powered usb hub for example
Thank you.
I don't have a powered hub, nor a regular hub...
So I'll try to make a usb y cable that will power the mouse/keyboard and see if that will work.
Edit:
That did the trick.
Made a Y cable that connects the data between the phone (with OTG cable between) and device and an extension that connects both to power only (currently from laptop usb).
At first it didn't work at all but after a few tries it started to charge the phone, allowed me to connect a DOK and a mouse.
However didn't want to work for a 250HDD or a pen tablet.
I ordered a usb hub and hopefully it will allow me to connect several devices at once.
Thanks again.
I've messed around with this quite a bit. Unfortunately, it seems Faux kernels don't work great with a variety of devices, but work fine for mouse/keyboard. Don't even work very well for USB flash drives and such. I don't even know where to go to report such issues.
This also means on Joker's CM9 it doesn't work great even if it should. Don't forget that CM9 port is still using a Froyo (!) kernel.
It's honestly not even worth building your own cable. You can get hubs that work for this for $5 such as this one:
http://www.dealextreme.com/p/cable-style-dual-power-1000ma-usb-2-0-4-port-hub-13526
Which is the one I currently have.
I'm currently using latest CM7 with the stock kernel and have no issues with USB flash drives.
It usually brings a notification of "preparing SD card" and mounts it under /mnt/usbdisk_1.0
I tried making 4 partitions on a flash drive, EXT2, EXT4 , FAT32 and NTFS .
Thought it only mounted one of them on /mnt/usbdisk_1.0 , it was easy to mount the others /dev/block/sda<1,2,3,4> onto /mnt/usbdisk_1.<1,2,3,4> thus having simultaneous access to all 4 partitions.
How ever the NTFS one only had read permissions since android and NTFS don't go together too well.
The hub you linked to is just a hub, I needed an OTG cable and ordered a 0.99$ usb hub that I will modify for power. so pretty much all set now.
As to reporting such issues, you could ask on the forums if other people have the same issues and how they get around them.
I got these:
http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774
I tried all sorts of devices, not least of which was a 360 controller. The kernels are very spotty at recognizing new devices being attached.
this is on CM9 of course
I haven't tried to replicate that on CM7 because, frankly, CM7 isn't supposed to support 360 controllers.
The hub I linked is very convenient. It already has a USB power lead as well as a lead for the OTG adapter.

Hello, I have both a new Galaxy S5 and a recently installed Windows 7 64bit PC.
I just bought an USB3 cable and tried it: when I plug the cable in an USB2 port, all works as expected (Windows warns the device can go faster if connected to an USB3 port); when I plug the cable to an USB3 port, the phone says connected to USB, message disappears, appears again and then definitely goes away (just charging); Windows says the device is not recognized.
I asked where I bought the cable and they changed it with a new one, but the effect is the same.
I tried installing latest Samsung USB drivers (1.5.51.0) without succcess.
The phone is not rooted.
Can you please assist in solving the problem?
Thank you!
USB 3.0 drivers installed for the motherboard?
How can I check? Windows says the device can go faster with USB3, maybe this means they are installed?
Go to your motherboard manufacturers website, drivers section, and look for USB3.0 drivers
For mine they are called ASMedia_USB3
Windows saying they can go faster with USB 3.0 just means windows has detected a USB3.0 device
Ok, I went to Lenovo Thinkpad download section and installed Interl USB3 drivers; I'm going to reboot
If that doesn't work, check your BIOS for USB3.0 settings, see if there is anything in there you can tweak
No luck...
I'm not sure it is on the PC side: I tried an USB3 mass storage device and it goes faster...
Maybe the cable is faulty then, or not up to USB3.0 standards
Is it a genuine S5 USB3.0 cable, or something from ebay or somewhere?
It is from "somewhere", but this is the second one with the same problem, chances are lower...
Second one from the same place?
Worth trying a genuine cable, the most likely culprit is a cheap cable from 'somewhere' rather than a PC or an S5
I'll try as soon as I find one!
What I wanted to check was if there's anything to "enable" on the phone or Windows.
Not that I know of, although I've not used a USB3.0 cable on my S5 yet - I haven't seen anything in the phone settings, and I know that my PC USB3.0 works fine without doing anything other than installing the drivers
@pdario
Please check you marked in phone 3.0 mod.
(when you plug to 3.0 usb port, you have option in phone to choose USB 3.0 mod)
Work?
The phone does not say it is connected to USB, it only shows it's charging.
So that the problem.
Unistall all android devices drivers you have, then plug the galaxy s5
How can I uninstall all the drivers? Where do I find them?

hi first i am a noob and learning meanings of terms used.
I have looked at threads with similar titles but they appear to be having a different issue.
Back ground history.
My SD card ext fried with all its data so I decided to go down the route of using an usb stick for storage. I am currently waiting to receive a usb 2.0 stick which can both be plugged directly into the phone or via my otg cable.
In the meantime my Problem has been experienced connecting a usb 3.0 stick to an otg cable. My phone does not recognise that the usb stick is connected. The otg cable is ok. I have used it to type on a keyboard. Previously.
When I plug the otg cable in the symbols come up at the top left corner of my phone showing that a usb connector is plugged in. I go to look at my storage and there is mo usb there. My usb debugging is ticked. if i have a look under usb tethering the option to tick is muted as it dirsnt recognise the usb is connected.
I did briefly see a suggestion somewhere that it could be a kernel problem but have been unable to locate the thread that this comment referred to.
I have a note 3
sm-n9005
a couple of days ago I managed to root it using towel root and downloading a link via this forum to revert the kernel to an earlier one so towel root would work. I then followed the link instructions to install the second kernel. The root appeared to work without too much problem. i ran root checker after and it said all was ok.
I am unsure whether the root has any relevance to the problem as when I google the usb stick is not recognised there are heaps of similar problems. Unfortunately though I have read many of the threads I still cant find an answer that helps me.
Could you nicely give me some advice. Thanking you
How was the USBstick formatted? Android can't use NTFS, you need to format it as FAT32 or ExFAT.
Well I was prepared to look extremely abashed on reading your question to me reformatting. luckily abashment could be deferred this time.
On looking at the usb stick it was formatted as a fat32. So I tried the other type of formatting you suggested. It still was not recognised.
The computer could recognise it.
My friend had a usb stick 2.0 which I then plugged in. a eureka moment was experienced. Mass storage message appeared.
So the problem appears to be with usb stick 3.0
I know the otg cable was originally designed for the 2.0, my understanding is that it is also supposed to work with 3.0
Any thoughts of why not?
Btw still havnt figuered out how to use the forums thank you process (where it is located?) Would love advice with that as well.
Thank you

USB 3.0 is actually USB2.0, the small addition on the side is the 3.0 part. It's completely backwards compatible.
It could also be an issue with the OTG cable itself. Do you have any other device to test the OTG cable with? (Tablet, etc)
Oh, the thanks button is located bottom left of a post, at the bottom underneath the poster information.
Thanks for the reply. I guess this will remain a mystery. I must admit to scratching my head about the possibility of it being an otg cable problem as the phone recognises when the cable has been plugged in and the cable works with both keyboard and usb stick 2.0
All I can think of is that elusive past post referenced on xda forum that referred to kernel issues.
Many thanks for your responses. (Still cant find thanks button) could be because I am using phobe as I dont have a p.c.
Hi,
So I'm developing an app to communicate over serial with a HID and testing on the g6 is proving troublesome.
The scene:
-Hid/USB Permissions granted
-Device filter correct and working as intended
-Goal is to send a string over serial.
Allthough I'm 100% sure my test code is correct, the app cannot open a serial port.
Is it normal behaviour in recent versions of android for the device to recognise an otg cable as a power source? Even with no other device connected? Are there any known issues opening serial ports on the g6? (7.0)
The cable works as intended when I plug a mouse or keyboard in but refuses to open a serial connection when my takget device is plugged in. It recognises it as a HID an can pull the serial number etc.
The android serial library should not require root or any other hackery So I'm a bit confused. I've ordered a few other otg adapters just in case.
Anyone who knows what might be going on pleas pitch in.
I've had some issues getting a serial adaptor working as well. I'm on 870DS. Originally tried the wired version of this:
https://forum.xda-developers.com/an...odemu-connect-android-to-30pin-t3234840/page1
Thank God the developer changed to Bluetooth. I tried about 6 different otg cables. Worked fine on other non usb-c phones.
I suspect it is the adapter too...sucks so bad. The annoying thing is that I was so confident in android serial that I wrote a lot of code before I bothered testing the concept lol.
Does your OTG work on memory sticks OK? I have a G6 h870ds. My OTG only works for me with USB3 OTG adapters and USB3 memory sticks. I don't have a USB3 HID device to try. I now have a large collection of different OTG adapters and memory sticks. I opened up some of the adapters to buzz them through to make sure they were made correctly. They were! It took a while for the penny to drop why some things worked and some didn't!
I cant use USB2 OTG adapters or USB2 memory sticks, keyboards or cameras. Initial connection of the USB2 OTG adapter is recognized but no connected devices are detected. I used an app called USB Device Info that can give me details of detected devices and only USB3 devices are ever detected.
I have a USB2 memory stick with an LED on it. When it is first connected to the OTG cable it flashes in a way that leads me to think it is trying to reply to USB bus interrogation but something (probably software) fails. The phone connects to my USB2 PC port just fine so I don't think the hardware is at fault. I've reset the phone and upgraded to Oreo too but alas that didn't help.
A friend of mine has a G6 H870S and all my adapters and memory stick combinations work fine on his phone so I find myself wondering if I'm just unlucky or whether the dual sim version is subtly different in some way.
I fully admit I know nothing about the inner workings of USB but as far as I can determine USB3 uses all of the USB2 connections and the additional connections only available on a USB3 port so the hardware should be OK. I'm guessing most HID devices are USB2 but if its a USB3 could you possible have a related problem but in reverse?
Every time I plug in any USB OTG adapter I get that same pop up screen that defaults to select as "power supply" even with no device connected whatever I have previously chosen.
What works for me is to plug in the OTG adapter, and only then plug in the memory stick to it. Otherwise I get the "Power supply" thing too.

Leaving just the OTG adapter connected for a few seconds then attaching the usb device does not help. USB2 devices are never detected but all my various USB3 memory sticks work reliably when using a USB3 spec adapter. I've given up worrying about it now and accepted that there is just something a bit iffy about my G6.
