<![CDATA[USB connection to my Pixel 3A not working.]]>USB connection to my Ubuntu Desktop and Laptop computers does not work anymore. Lsusb with my Pixel3A connected or not produces the same results. I'm on the stable channel of Xenial OTA 25. Has anybody encountered this problem before? This makes file transfer very difficult. I have tried the same with my old Aqaris E5HD also on Xenial OTA 25 stable. It connects without a problem and I can read and write files on this device. Thankful for any help.

I'm not sure what caused it, but I think it may had been something like the utadblocker app but I'm really not sure.

Weird since I used the same setup (laptop, phone and cable) to just minutes before flash the PQ3B.190801.002 factory image and then install Ubuntu Touch. Do not even think I disconnected the USB cable anytime during the process.

If you have replaced the cable
Tried another USB port
Tried another device with the same cable and that device connects
Tried another PC
Tried another Operating system
Installed Android Studio to get the most up to date ADB and fastboot drivers on the PC
Cleaned the devices USB port with 99% Isopropyl alcohol
Your device is second hand and you don't know its history (lots of eBay devices)

All the above fails to connect with a PC then your devices USB port is faulty and needs to be replaced which is no easy task on any of the Pixel phones.

I have numerous USB cables and have tried sometimes 5 different ones to get a contact.

According to my research, you should try the solution described in the following link:

https://urukrama.wordpress.com/2009/01/27/usb-drive-not-recognised-error-71/

If you can rule out hardware issues, such as cable, power supply (if you have a USB hub in between) and or low battery (on the Phone or even Laptop).

Good luck 🍀

Greetings Mario
