Detailed description：
3 November 2020, i updated my bios from 309 to 311. But i've some bugs with my usb port. When using usb hub, on first port (beside hdmi port) will randomly disconnect and reconnect every 5 - 30 minutes. And without usb hub you cannot transfer file to android phone (cannot change 'transfer file' option on android phone). And for the second one (beside type c port) with usb hub i think no problem, but new problem if you connect your android without usb hub, it will connect and reconnect every 1 - 2 second.
Summary:
Problem First USB 3.0 Port (Beside HDMI Port):
With USB Hub, it will randomly disconnect & reconnect every 5 - 30 Minutes
Without USB Hub i think its normal, but cannot transfer file to android phone (only charging option)
Problem Second USB 3.0 Port (Beside Type C Port):
With USB Hub no problem occured
Without USB Hub (Direct Connect) Android phone will disconnect and reconnect every 1 - 2 second
I hope asus will fix this fatal bugs

Hi Guys,
I had exactly the same issue. It was soooo frustrating. I'm using a USB hub too.
Even if I plug my mouse and keyboard directly into the laptop, aslong as the USB hub was still connected, it would still glitche out my mouse and keyboard.
I flashed my BIOS back to v309 too, problem solved.
I highly recommend going back to v309.

Dear all,
New BIOS is on the way to solve this issue. I will keep you updated.
To solve current situation, please downgrade to previous BIOS.
Sorry for the inconvenience caused.
Thank you.

Could you please tell me how to downgrade BIOS version to 309?

Hello viswanth,
Please kindly use EZ flash to downgrade to 309, the same way as upgrade.
Thank you.

Thanks for the fast reply but I upgraded using windows installer.
How to use EZ flash?
You put the .309 file in an FAT32 formatted pendrive and put it in when you are EZ flash utility in BIOS. Does that sound right?
