[SOLVED] Android USB constantly reconnecting

Plugging in my phone, regardless of the connection type chosen from the device (File Transfer, USB tethering, MIDI, PTP, No data transfer), makes it dis- and reconnect like crazy. Following output from journal -b with root privileges:

Jun 18 19:45:51 dell kernel: usb 1-3: USB disconnect, device number 7

... And it keeps going.
This hadn't always happened, however I don't know what might've caused it. I've tried all 3 USB ports and checked that they work with some mouse I have laying around, so the problem doesn't seem to be on their side.
I doubt this has something to do with autosuspend, nonetheless I've tried blacklisting this specific device and it didn't change anything.
My searches could only find this, which happens with a touchscreen.

Trying a different android phone works and produces following output in journal:

Any ideas? Thanks in advance.

Re: [SOLVED] Android USB constantly reconnecting

Does the phone work properly on a different system (Windows)? What Android OS is installed? Custom rom? Then try USB in TWRP/recovery. Try a different USB cable. Check logcat on Android side.

Re: [SOLVED] Android USB constantly reconnecting

1. No. Tried on same computer with Windows 10, it keeps showing the notification for the new device.
2. ArrowOS
3. Yes
4. Same, but with new error messages:

...
Jun 18 20:54:37 dell kernel: usb 1-3: new high-speed USB device number 117 using xhci_hcd
Jun 18 20:54:37 dell kernel: usb 1-3: Device not responding to setup address.
Jun 18 20:54:38 dell kernel: usb 1-3: Device not responding to setup address.
Jun 18 20:54:38 dell kernel: usb 1-3: device not accepting address 117, error -71
Jun 18 20:54:38 dell kernel: usb 1-3: new high-speed USB device number 118 using xhci_hcd
...
Jun 18 20:54:44 dell kernel: usb 1-3: new high-speed USB device number 125 using xhci_hcd
Jun 18 20:54:44 dell kernel: usb 1-3: device descriptor read/64, error -71
Jun 18 20:54:44 dell kernel: usb 1-3: New USB device found, idVendor=X, idProduct=X, bcdDevice= X
...

For the " device not accepting address X, error -71" the address is different everytime.

5. Don't have one unfortunately.
6. Logcat when plugging in:

So it's clear that the problem is with my phone, the last update must've broke it.

Re: [SOLVED] Android USB constantly reconnecting

So, apparently restarting while having the device connected solves the issue? Weird.

Re: [SOLVED] Android USB constantly reconnecting

This is a typical scenario for a weak cable. I would check that first.

Re: [SOLVED] Android USB constantly reconnecting

I've just remembered I have my older phone's USB-c cable, the issue persists however. Since my current Android version (11) is no longer maintained by the developers of the ROM, I'll upgrade to 12.1 in the upcoming weeks and report back, I'm now fairly certain the problem lies in the ROM.

Re: [SOLVED] Android USB constantly reconnecting

You could ask on XDA. If it's a bug indeed you're probably not alone. But if TWRP is affected as well it might be rather the kernel or a hardware issue.
What device is it?

Re: [SOLVED] Android USB constantly reconnecting

I've searched for this problem in the ROMS Telegram group but I didn't find anything, and I would ask, when my software was up to date, but even my TWRP needs an update. As far as I'm aware, the ROM comes with the kernel. Honestly I don't find it worthwhile looking for this on XDA with the god awful search function just to find a post telling me to update. I'll just update everything all together when I have time. For now, I'll keep using samba for file-sharing and restart when I need to flash using PC. Should I mark this as solved/closed?

Thanks for the help.

Yes, you can mark as solved.
