cable two is usb-2/3
when im connecting usb stick that has music
sometime it works and sometimes not (i tried several usb sticks)
when im connecting my iphone thru a carplay dongle it says charging but autokit carplay sometimes works and sometimes not (but the dongle has light that is always on when connecting it to usb)
anyone have an idea what is going on?
Is it an MTCD/E. Also, would help you to list steps taken to resolve, including contact with reseller support
Yes

Try different usb , what kind of usb stick do you have usb version 2 or 3 ? Sometimes usb 3 sticks are not working or are not detectable from various usb roots. Try with standard usb 2 sticks and see if works correctly. This is first thing you can try.
Second thing, see if usb cables are having defects on wires on end that connects to head unit. Maybe one of wires of usb ports is not connected or wired correctly.
Hey
Both usb 2 + 3
Also tried checking the cables they seem to be fine

I changed both the usb cables and the motherboard, without solving the problem
Yes
I upgraded from 8 to 9 and then to 10
Also newest mcu
Still not work properly

Hi guys, do you know any cable/adapter that has all these ports?
I'd charge my tablet while I've a pendrive inserted into it and connect all via hdmi to a monitor/tv.
Did anyone try something like this? I'd like that all ports work all together at the same time.

Something like this? It has USB in, although I'm not sure if that's for pass through charging or just device inputs...

I have one of these and it works with Note 10.1 2014 - to some degree.
Basically HDMI and USB work - at the same time.
I can connect my tablet to external screen and use USB mouse, keyboard and flash drive (through USB Hub) all at the same time.
But... USB connection is kinda unstable - devices disconnect occasionally and then reconnect.
Also, charging doesn't work at all.
On my Note2 everything works OK - I guess Samsung changed something either on connector or in software in Note 10...
I'm not able to get to the bootloader screen because the front usb port is not functioning on my unit. Has anyone been able to use one of the USB ports on the back to get to ADB and/or get to the bootloader? Is this a known issue with a workaround? I've done quite a bit of searching and have not turned up any solutions. Considering what is involved in shipping this back, I'd much rather figure something out. Thanks in advance for any help!
Edit: I should mention that I have used the adbon password and it does acknowledge that adb has been enabled. Just nothing seems to work on the front port. When I connect my Linux machine and run lsusb nothing shows for the unit. I have considered buying or making a USB-A to USB-A cable to connect my computer to one of the back USB ports, but I'm concerned about how these back USB ports are designed. Is it as simple as a built-in OTG cable? If so I'm probably fine. If it is more like a computer's USB port I could damage my laptop, my headunit, or both. I'd really like to hear if anyone else has had to deal with this. Unfortunately I haven't verified if the front USB will charge a phone. This is my next step.

My front USB also doesn't work. I even got mini to standard USB cable with unit, but plugging flash drive into it doesn't produce any reslt.
I also plugged extension cable to one of back USB ports and tried it (plugibg same USB flash) but it doesn't work either.
So I'm also confused.
Does that mean you are still running the stock ROM? I have been hesitant to install the custom ROM because they say you must be able to get into the bootloader even though I couldn't find a step in the process that required it.
Regarding the USB ports not working at all, you may find that you need to use a powered USB hub. I've seen reports of USB devices acting up due to the low power. This is one of the reasons I thought it might be safe to use the rear ports with my computer. (My first real test is going to be mangling a male-to-male USB cable so only the data lines are connected to see if I can get those rear USB ports to talk to the computer. I figure that way there is no chance of frying any circuits.. Each side already has its own power and I don't believe any signaling is sent via the power pins.)
On my unit (MTCB-KGL-V2.80), I have used a T-Mobile USB broadband modem successfully on the rear port, so I know rear ports are live. I did take it apart to see if something was obviously wrong with the front port, but nothing jumped out at me.
So I have a bit more information on my headunit. BTW, I have the BMW E46 model with MCU MTCB-KGL-V2.80.
On my system, both the front USB port and the rear 3G USB port are wired as device ports connected to an AU6258 USB controller (http://www.sunnyqi.com/upLoad/product/month_1403/201403162331285643.pdf). I don't remember exactly which USB ports they are connected to, but I believe the 3G port is connected to port 2 (pins 6 & 7) and the front USB port is connected to either ports 3 or 4 (pins 9 & 10 or 11 & 12 respectively). Nothing is connected to port 1 or to the upstream port. The other rear USB port is wired directly to the MTC_RK3188 board.
All three ports are wired with only four pins, so I'm concerned that none of them could work with the computer. The USB controller doesn't have USB ID pins, so does that mean that the 4 downstream ports are OTG and the upstream port is for a computer? Unfortunately I don't know the hardware side.

No I flashed Malaysk ROM from GPS SD card. No problems. Just follow instruction. I had luck that I didn't need to recover from USB.
Did you tried with USB powered hub? I don't have one to try it myself.

I think it was intended to facilitate moving files from an older phone. Mine is due to arrive any moment. I think we will all have some real answers soon.
Except most old phones do not have USB-C

You plug the USB C end into the Pixel and then use another cable to connect an older phone (presumably one you're already using with the older phone). Micro USB/Lightning into the older phone, USB into the adapter. The adapter can also be utilized for OTG - USB C into the Pixel, flash drive/other USB device into the USB port.

Also to use OTG. Plug that in, and you can hook up a keyboard, mouse, removable drive, someone elses phone, whatever.
Could someone clarify. I plugged the adapter in how I was directed by a thread at the "pixel community". The thread referenced a way to use the adapter to transfer files however I plugged it in set the settings to xfer files and nothing. Does the adapter go into the pixel or the (in my case) Note 7? The thread listed a way to make these transfers upon start up but I'm way past start up. I need to transfer a couple apps and a big phone log and a truck load of texts. Any help out there?
I just received the phone and tried to use it with this dock with no results (the power led lights on and android P notifications shows the connection with a USB device, however it is not properly recognized).
I tried with an USB key, a mSD and with a HDMI cable attached. Any advice on alternative solutions? (both HW and SW).
I wish I could relate or let alone try to understand what you just said. I would have been fine with typos , but clearly your sentence structure is off even without proper punctuation. Regardless, thank you for the information sir.

Thanks for the tip Sir. I rewrote the sentences in a clearer way to make them easily understandable.
I was using a third party DASH cable originally for my OP3, with my OP7P and noticed it does the same thing as your dock. Side note the OP7P could not be recognized in fastboot with said third party DASH cable.
But the OEM cable works without fail ever time could be pin/or chip? configuration but I don't know enough about Warp/DASH/VOOC to say.

I made some further tests and these are the results:
- With the dock powered with a PD cable (so charging the phone as well) the video signal works as expected but no other devices are recognized (I tried a USB key, a keyboard and the usual microSD but none are visible)
- Using a simple USB-C to HDMI cable the video out works like a charm
I think the USB issue might be related to the drivers needed to identify the device (a similar situation happened to me on the Nexus 7 several years ago and I fixed it changing the kernel). For now I think I will have to find a different dock. The best one for my needs should have 2 USB, mSD slot, HDMI and Ethernet. Any tips?

One further update:
I used the same dock on the Mi A1 with Android P and it is properly recognized with both the mSD and the USB key attached. Obviously there is no HDMI out since the port is only a USB 2.0 one rather than a 3.1 like the OP7P.
At this point I think it might be related to drivers only, because the notification for an attached USB is there but it is not simply recognized (to be honest if i use the PD-USB while having the mSD inserted, the phone is charged but no popup for attached USB device is shown in that case).

Yeah I'm having the same issue, tried an HP dock and a Dell dock. Neither one supported USB. I don't understand why this is, never had this issue on older model Android phones. Must be the drivers.
FYI - The HP one displayed the picture on the monitor via HDMI, but wouldn't charge the phone. Dell one would charge, but wouldn't support the monitor. I have another model Dell dock that I'm going to try next week that I think will work better.
Another quick update.
All the test were performed with OTG on and with USB debug enabled and disabled to see if there are any differences in results(no differences for now)
Atzbee Dock
- HDMI Out working even without an external power source
- No USB drive/key detected
- Phone charging works
EC Technology Dock
- HDMI Out working even without an external power source
- No USB drive/key detected
- Phone charging works
So how can we escalate this to OnePlus? We should not be having these problems.
I made some further tests with several devices.
original OP OTG
Works with every device so far (not tested with Ethernet)
Vava 8 in 1 old & Vava 8 in 1 new
HDMI, USB flash, sd card and transflash work at the same time (even without an external power source).
I am finding problems in the connection of a keyboard or mouse that are never recognized (except for the original OTG cable)
Ethernet is never recognized.
To make sure before I buy one, the vava 8 in 1 hub works with usb flash drive while charging the phone?

Yes (on USB 3.0), however it is confirmed that is a limitation of the kernel, since flashing a different one seems to make everything work smoothly as reported here.

it works on USB .3.0 on hubs with stock kernel, but no keyboards or mouse (charging always worked for me). Modifying is needed to achieve the full functionality of the hub
You have to flash a custom kernel to get the USB type C keyboard and mouse working! Stock kernel does not work! Flash it and whalla! read my thread. https://forum.xda-developers.com/oneplus-7-pro/help/otg-usb-hub-recognizing-mouse-keyboard-t3936188
I just want to report that this issue has been resolved with Android 10. The HP dock I was using now supports the keyboard and mouse. Display and charging also still works.
Well that's a huge bummer, I regret buying the tmo variant. I reported this and chatted with one of the people there about pd+otg issues. I am able to get usb hubs to work if plugged into a c-typeA(f) adapter. That of course means no PD or HDMI, so it's awesome that Android 10 includes that fix!

Hello quentin0, could you please share with us the model of the hp dock you are using ? Thanks a lot !
Everything works, SD card, Ethernet, HDMI (Desktop mode or Mirror which one you want), Keyboard, Mouse, Flash drive. https://www.amazon.com/gp/aw/d/B07XRJDMLD?psc=1&ref=ppx_pop_mob_b_asin_title
Rooted but stock kernel even charge the phone but slowly if you supply external power.
Android 10.3
Wow exactly what I was looking for... Thx a lot !
I have a USB OTG cable that I can use to connect USB devices like flash drives, keyboard etc. and that works fine, but for some reason my phone won't charge whilst the OTG cable is plugged in.
Am I missing some really obvious way of getting this to work? Is it software based? I'm rooted and running Lineage OS if that makes any difference. I've tried several different OTG cables, I've tried connecting to different power supplies, different USB cables, different outlets, I've tried going into developer debug settings - nothing seems to get it to charge and data at the same time.
I am also interested in the topic. Trying to run Octoprint for Android and charge at the same time. I bought an OTG Y cable and the problem is that the phone is either charging or communicating with the 3d printer. Never both at the same time. I've researched quite a bit on google and it turns out at least on some devices the required effect can be achieved but I haven't been able to find anything about huawei devices. It is most probably a software limitation.
The same problem but i have Samsung J5 2017, i have rooted device so there is option to modify system files
Gosh! Would love to get this working. Any news?
