Hello, I have a Sony X Xperia Performance. Stock firmware 41.3.A.2.149 has been flashed. Full wipe was also done with TWRP 3.6.0_9-0_dora.img. I have tested several ROMs: ,,lineage-18.1-20210802-UNOFFICIAL-dora.zip" and ,,crDroidAndroid-9.0-20201123-dora-v5.12.zip" from XDA.
Both ROMs doesn´t allow USB adjustment for file transfer (MTP) under "connected devices" in the settings. But if I go into developer options, enable USB debugging and go into default USB configuration, then I can turn it on.
What is the reason? What am I doing wrong? Thank you!

My USB has no issues when I'm in Stock 2.2 and 2.3.3 ROMs until I flash a deodexed 2.3.3. I have to frequently change ports with my Windows XP to get the USB Mount option. Previously I was able to connect to Macbook with no issue. After flashing with deodexed, Macbook does not read my USB at all. All my USB cable did was charging my phone.
Well, I know it shouldn't really matter but you could try switching the USB mode by going into Settings >> Wireless and Networks >> USB Settings >> Mass Storage.
You can also make sure your USB debugging is turned off by going into Settings >> Applications >> Development and untick "USB Debugging"
Does anyone know why PTP mode would not be retained across a reboot? It seems to revert to MTP when rebooting into either the bootloader menu or into regular user mode.
I am trying to unlock the bootloader on my Nexus 6 running the latest build N6F27C of 7.1.1 that was sideloaded over 7.0 using ADB from my Mac. Now I'd like to start again and perform a clean flash of the 7.1.1 using ADB.
In normal user mode I can enable USB debugging in Developer Options and when PTP USB mode is selected then ADB will list my device just fine, I can trigger a reboot, etc.
However, after rebooting into the bootloader menu ADB shows that it has lost connection with my device, even though the screen shows that USB is connected. The ADB device list is empty.
On subsequent reboot into user mode I can see that USB debugging mode is still on but PTP connection mode has reverted to MTP, which (at least on a Mac) can account for ADB's lost USB connection to the device.
ADB debugging in PTP mode has worked fine for me in the past, but the phone now has been through several factory resets and restores from Google's backups, plus it is on 7.1.1.
Hi,
i've done a clean LineageOS 15.1 with pico gapps on my galaxy tab s2 (gts210vewifi). But i'm not able to use the usb modes, the only thing i can do is charging. The notification for usb mode is missing.
If i plug-in an usb cable (tried many different) the device is not detected as any sort of device (lsusb didn't show anything). I also tried activating the developers options and enable usb-debugging. There are also direct/default mode change for usb and changing this (and replug) also had no effect. I'm sure thats a problem in combination with this device, since on the initial flash with lineage microg as well as the first flash this works perfectly. But after some time (or maybe a reboot) the notification isn't shown. Even a full flash (except the memory card) didn't change anything
I can't pick any option when I connect the phone to the computer, they all are greyed out. The only way to transfer files from my phone to my PC is through TWRP or changing the default USB option through developer settings.
Can someone help?
Can you attach screenshots?

This happened with me on my phone's stock image. All the usb options were greyed out. I tended to look for solutions, but couldn't find anything relevant. Then, with a later update, it got fixed. However, now I'm using a custom rom(Resurrection Remix), so there are no issues with USB atm.
I would suggest you to install a suitable and stable custom rom(Lineage OS, is the best) on your device. It might help.
If you are on Lineage (You don't say) just set the USB option to always transfer in developer settings, Plus make sure USB debugging mode is turned off.
When I connect my Mi 9 Lite to PC via USB cable, it says that the device is not recognized. I tried 2 different computers, and 2 different cables, same thing.
I tried reinstalling the drivers etc, all the online tutorials for fixing, nothing.
Anybody else had the same thing happen to him, or maybe has a suggestion what to look for?
Thank in advance.
Hi, enable USB debbuging
go to settings -> "my device" (or similar) and tap on your build number multiple times. go to "advanced" -> "developer settings" and check if "Select USB Configuration:" is set to MTP for file transfer or PTP for your Android to play a digital camera storage.
