HI
I can not use the digitizer and want to save the compelet device.
It is NOT rooted with android is 5.1.
I can use the pad with external mouse/Keyboard via OTG cable
Debugging is generaly on, but never used before.
When i plug in the pc via cable on that only usb port, i'm asked to allow the security certificate .........
But at that moment I have no mouse connected, when i switch cable, the dialog disapears.. Catch 42
Tried it with usb hub... no way
Anybody any idea how to solve that deadlock ?
THX

Hey guys!
I've searched and searched for something to allow me to transfer data via a serial cable from my phone to device.
Let me try to explain this.
HTC Wizard
Windows Mobile 6 (Explore 1.1)
I have style tap (palm os emulator)
Software for palm os for a stand alone fuel managment system (msefi.com)
So on my car, I use a serial cable to program and get realtime data.
Now I know they make bluetooth to serial adapters for around 70, but I was wondering if they make a mini usb to serial cable for the Mobile OS.
Anyone have any ideas?
Thanks
Chris
Well, you could theoretically get a USB to serial adapter that has a cable. Then cut the USB connector that goes to the PC off the cable and just splice the miniusb plug onto the end. I don't know about device support though I'm going to guess you would have to at least come up with a driver and the device might not support that type of functionality at all anyways.
Since the Wizard doesn't have a USB Host (aka USB OTG) the short answer is no. Even more importantly, the wizard won't power the serial adapter so the device is a dud to begin with.
The odds that the BT to RS232 connector method will work are far greater than the USB method.
Hello guys, recently my micro usb port is not working properly, the pc's can't detect it(tried 4, mac,windows and linux os's) so is not the computer, changed 3 cables, so is not the cable, something must be wrong with the micro usb port, it can charge(usb, wall power) with no problem, but the phone is not detect by pcs, adb, etc, any idea what could be the problem? how can it be charging and the usb debbuging protocol or whatever isn't working, can I screw the transfer usb protocol? but the charge protocol in the same micro usb port could be still working, thanks in advice!

I had the same problem as you, it was impossible to make any computer to recognize the phone. Moreover it charged very slow, the phone thought that it was always plugged to the computer even if it was connected to the wall charger.
I did a factory reset, but the problem persisted. I called Google and they sent my a new phone, which now works perfect.
So I have an LG G2 with a broken screen. You can still view the screen but the digitiser is broken so I can't use the phone's touchscreen. I bought a micro usb to usb otg adapter which I can use with a mouse to control the phone.
I want to root the phone and I have everything that I need and I know exactly how to root the phone. The only problem is that I have to trust my computer for usb debugging. I have turned on usb debugging using the mouse and the otg adapter but when I plug the usb cable into my phone and connect it to my computer, I obviously can't use the mouse. The confirmation then comes up asking whether or not I want to trust the computer but I can't press "yes" because the digitiser is broken. I was wondering if there is a way to bypass the authorisation confirmation so that I can root my phone. Any help would be greatly appreciated.
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.
Hello everybody. Asking for help and suggestions. Maybe LENOVO representative take notice. Have secondhand yoga book. Resolved almost all problems but micro USB port. First of all, charging device died out. Find 30-watt charger with QC 3.0 and charge now working perfectly. Next tried to connect mouse, usb hub and usb dongle. Each time got DEVICE NOT RECOGNIZED message. Got error in device list.
But......tried to connect external HDD with noname HDD box and it connected. Connection may work to copy, install files or disk may disconnect randomly.
Tried system restore, tried to change drivers ( intel drivers for chipset not avaliable now) with no luck. Think problem is with low port current, but even small mouse and dongle make error and non-SSD HDD work 9 times out of 10. Have anybody experience problems with connecting devices to micro USB port?
Tried 3 different OTG cables and OTG micro USB to USB dongles. No luck.
Maybe the port is corrupted or desoldered

I did change it with the warranty I had. I had the same problem and did not want to fix by myself as the warranty was still active
