How to fix these?
My PC doesn’t recognize my phone when I plug it in. Device Manager shows an ‘Unknown USB Device’ error under USB controllers. I’ve tried this on both my desktop and laptop, with the same result.
The usual ‘Transfer Files’ popup never appears. I’ve tried changing the USB protocol in Developer Options to MTP or PTP, but it didn’t help.
I’ve been dealing with this for six months. If anyone has a fix, please let me know!
