Hello,
I have this phone here and it has some problems with connecting to the pc. Every time I connect it, my pc says "Power surge on the USB port". I have tried this on a USB 3.0 port as well.
Does anybody know how to fix this?
One thing that might be a little off the subject, but figured I'd mention in case anyone had any input is, the Astell & Kern DAC when plugged to our device does absolutely nothing; no light, and no power.
When I plug it in the OnePlus 8 Pro, it works like intended. I would love to know why this is the case, and if it would be possible to work on our 9 Pro.
Thanks

I know a few other phones have managed to enable OTG host mode and charging simultaneously via a resistor on pin 4 (ID/sense) of the usb port. This apparently enables dock mode. I know the SIII does it as well as some xperias. Anyone know if the note has a mode like this, and what the resistor value is? Galaxy nexus its possible to patch the kernal to disable the boost mode from internal battery on OTG host mode. Anyone done anything for the note?

In my limited knowledge, I have just tried one of these with no success. No mods to the cable or the kernel or anything. Just wishfully hoping it might work. It does not. I am not even sure it is getting power to the USB device properly. I am trying to run a small Seagate FreeAgent disk drive. As expected, it runs fine when plugged into a USB port on my desktop or laptop. Plugged into the OTG using the standard OTG-type cable or this Y cable - without additional power - yields nothing as I would expect. Applying supplemental power to the Y cable from either a PC USB port or from the phone's charger gets the drive making a little noise and lighting up. But the phone still does not recognize the device. And I hear this slight pulsing noise from the disk itself that is not heard when plugged into the PC. Alas! Perhaps it needs yet more power. But all I have is either what comes from the USB port on the computer or the 1A max from my phone's charger.
Added later...
I have actually discovered that the Y cable works as a normal (not power supplemented) OTG cable for thumb drives, etc. But adding supplemental power to the thing makes everything stop working. The thumb drive which was working prior to adding the power cable stops working. With my Seagate drive (which requires additional power) plugging the Y cable into my phone makes the drive shut down after a few seconds.
It appears that either the USB port or the USB controller is failing (has failed). The phone still charges but neither the phone nor any computer recognizes that the phone is plugged in. Even when I plug the phone into a wall jack, the phone does not make any sound or light up or show it is charging (it does charge though). If I go to the battery settings while the phone is plugged in (computer or wall) the phone recognizes that it is charging.
If the phone is off and I plug in the usb cable (compter or wall) the phone turns on by itself. This is problematic because I cannot get into the download mode using the 3 button combo. I also cannot get into the download mode using apps like Reboot Widget.
I installed USB Host Controller which says that the USB cable is not plugged in when it is. I can disable and enable USB charging though. Changing the USB Host Drivers has no effect.
So it looks like I need to send it into mobiletechvideos for repair. But reading through the reviews there is concern that just replacing the USB port wont fix my problems if the USB Controller is shot.
Not only did they replace the USB port and get it back to me in about a week but they told me that since the controller had failed and the phone couldn't talk to the computer I wasn't charged the full price for the repair.

So I guess I'm asking if anyone here knows anything about this issue and if mobiletechvideos.com can repair it.
I am also going to email mobiletechvideos.com asking them this same question.
Thanks for your time.

Mobiletechvideos (Connexion2005 on xda) can most likely repair your phone. Him and Adam Outler have been doing the impossible with devices!
I'm looking for a cradle/desktop stand for the Mate 10 and can continue to use supercharge.
Anyone found one that exists? thanks
Not exactly what you asked for but these are the items I use, might work for you?
The port adaptor doesn't allow super charge but it can get up to 1200ma
Usage:
Connect my phone to the TV via HDMI streaming Udemy or Amazon prime for 2 hours and it easily charges the phone in the process, or playing games like Modern Combat 5 via HDMI & Bluetooth controller.
Also use it to backup the phone to USB drive, also charges the phone whilst doing so
Adaptor:
JAVONTEC USB C to HDMI Adapter with USB 3.0 Port and USB-C Power Delivery, USB C Hub for Surface Go, Dell XPS, HP Spectre, Chromebook Pixel, Samsung S8/S9, LG G5 More https://www.amazon.co.uk/dp/B0784GC6GD/ref=cm_sw_r_cp_apa_qLTbCbJK79Q0S
Stand:

Just bought this for the time being until something better comes along.

You just need to use your normal supercharge cable and brick... i dont understand to be honest. The charger is not connected to the stand in any way is it?
I am using the original charger and brick but I'd like to be able to plonk my phone on a charging stand without having to manually attach/detach the lead.
Like you can with this:-
https://www.amazon.co.uk/Charging-Y...544215428&sr=8-7&keywords=usb+c+docking+stand
...but keep supercharge.
I don't think USB-Ports are plonkable (even USB-C, which slides rather well compared to asymmetric mini/midi-USB) -- for plonkability you'd need either another interface or a cradle that guides the phone very snug on a straight path for at least 1 cm or so. And even with a perfectly guiding/sliding cradle you'd have to push the last millimetres for the plug to click (vice versa when "undocking" again).
There are magnetic plugs for all kind of USB charging ports that are plugged into said port (and left there) and will snap to their respective (kinda proprietary) magnetic charging cable. However, first and obviously, such a plug blocks the USB port it is plugged into (so you'd have to remove the tiny thing everytime you want to plug in headphones or whatever); second, I've yet to find one that supports Huawei Supercharge (or whatsitcalledagain).
Hello guys
I recently changed from S9+ to S21 and I have a question : I usually use my desktop computer to charge my phone during night while I sleep. (with data USB cable)
I have no problem when the desktop is on (under windows) : my phone charge (with USB cable) and I can transfert photos.
When my computer is off, when I plug the phone, the screen show the charging screen for 2 seconds and stops
I have no problem with my S9 to charge when the computer is off. (I know that there is an option in the bios to keep USB charging when computer is switched off)
It looks like the USB power is too low, and the S21 doesn't want to charge with it.
Maybe ther is an option in the phone to authorize this kind of charging ?

There isn't such an option in the OS as of now. It's possible that the S21 battery amp requirements are more than those of S9
Do you think the computer's USB port has a lower supply when the computer is turned off ?
We don't know what kind of computer you have, or what it's USB port capabilities are. That's something you can try to figure out, looking at your computer or manual for the computer's motherboard. Also check the BIOS settings, sometimes you can control the power state of the computer when it is "off" and whether power is still supplied to the USB ports (e.g., to allow the computer to boot up when it detects mouse or keyboard USB inputs).
As an example, my MSI motherboard has a feature where you can install software to set the USB ports to a high power output state, so you can power USB devices using more than the standard output current.
My Dell laptop has a USB port with a special symbol that means it's for high-power output for charging phones etc. So it can handle charging modern phones, and puts out more than 0.5 amps, but only for those USB ports with the special symbol (lightning bolt).
You'll need to just find out more information about what your computer is capable of.
I have a MSI gaming pro carbon X370 ( the optional wake by USB is on, without that, you're right, the USB are totally off and nothing will charge)
I did more investigations .... I tried all my USB cables and all USB ports and finally find 1 combination that works.
Only 1 of 12 USB cables worked ( the one took from an external HDD ) even the original cable supplied with the phone didn't work and nor a 100W Ugreen cable...
And only the front USB work. The different USB directly on the motherboard doesn't work with this phone, despite I always used them to charge many devices...
for information the working cable is a KAIBAO revision 3.0
Finally it doesn't work with this cable : it take longer before the phone stops to charge, but it stops too ...
Hi,
You need to check the power requirements of your new phone.
Thank you.
I think it came with android 12, the card reader is not recognized when plugged in. I have tried 3 of them. They used to work with my S21 Ultra. When I plug them in to my old P30 Pro, they work fine.
Also, I can't connect to my PC as I used to, now the only way is to use DEX.
USB debugging is on.
Any ideas folks?
You say it won't connect to your PC. I assume that means wired USB connection? And when you refer to Dex, I presume you mean you're using is wireless rather than wired?
Assuming those things, it sounds like you have having issues with USB data lines and the common denominator here is your device. My guess is a faulty USB socket or worse, damage to the board itself.
You don't mention charging issues but that would still work if the power lines are OK. Does the phone fast charge? That uses the data lines to provide extra power. If it doesn't then there is definitely a problem with them.
I would suggest this is a hardware fault and would need opening up and servicing or a replacement board. I cant help you with that though. Sorry.
No problems here with cardreaders or connection with PC or monitor with wired Dex connection (SM-G998B on G998BXXU4CVC2).
Suggest you first check your charging port for dust or debris. Clean with compressed (dry) air or gently with toothpick.
no problem with charging......wall socket or in the car.
I don't use fast charging
My little thumb drive still works...just plugged it in. As suggested, blow some compressed air in the USB port.

If the power lines are unaffected then your phone will still charge. Fast charging works by utilising the data lines to increase the power provided. Turn on fast charging (you can switch it off after) and plug your phone in to a wall socket. Does it fast charge? If not then there is definitely an issue with the data lines. This then confirms why connected USB devices don't work. As others have suggested, clean the port and see if it works. If it still doesn't work then it will need to go for repair. Virtually all Samsungs have a secondary board which holds the USB port and bottom speaker. This can be replaced.
