PC Cannot Detect Padfone S After FOTA Update

Hello guys,

I have problem with Padfone S after 6.0.1 FOTA Update. My phone is not able to detected on PC.

Before update it was directly detected as ASUS_T00N on windows explorer.
There is no notification on my Padfone S to choose "Allow USB File Transfer" like my other phone (Zenfone Max) when I connect USB cable.

Any help will be appreciated cause I regularly use USB to transfer my file from PC to phone.

How about using OTG device? can it detect USB?
Please try to connect with other PC/notebook to determine the issue.
have you checked USB debugging? please enable it.
