Asus look to not care

[PeterUK1]

Put simply I was once able to install windows by the BIOS USB port with a Integral Micro SD USB3.0 Memory Card Reader and over the new year I wanted to reinstall windows using that very reader and it did not work in windows to update the windows install in the BIOS USB port will no longer work last time I reinstalled windows was under a year ago and I have been updating the BIOS with a Kingston Memory Card Reader which to this day works in the BIOS USB and in windows but not the Integral Micro SD USB3.0 Memory Card Reader. Just to add it works in any other USB port but the BIOS ports when in windows

And Asus support are just saying Memory Card Readers are not support yet my Kingston works and Asus are failing to understand that the Integral Micro SD USB3.0 Memory Card Reader USED to WORK.

So I like to get others feedback on this just to see if Asus support is in the right

I just don't see the problem in using Memory Card Reader vs flash drives I guess I should be lucky my Kingston Memory Card Reader works I mean what would Asus do if I find a flash drives that used to work then didn't after a BIOS update? Would they fix it or say use another flash drives?

I plan to buy a mix of flash drives and Memory Card Reader for testing but more so for Memory Card Readers so does anyone here update their BIOS with a Memory Card Reader I would like to know.

So basically, you've got a card reader that won't work in the BIOS port any more. I think it's more likely that the contacts on that reader just don't happen to like the contacts in that particular socket. USB sockets and even the devices you plug in can eventually get wear on the contacts. Maybe they've got a little worn/damaged over time?

As far as I know, there is no difference between the ports in the sense that all support USB connections. It's just that the BIOS port gets read when you press the Flashback button.

Why not just use the Kingston reader if it works?

[PeterUK1]

You might think that but for easy use I have a good USB cable to the BIOS port plus I have another board the same type and it too have the same problem and then there is the matter of why it works in any other port! Thats just odd

Its like Asus went no we don't support this Memory Card Reader any more for use on the BIOS port any more. So it be interesting if any others have this problem.

Its this one
USB 3.0 MICRO SD CARD READER 180MB/S READ AND 130MB/S WRITE | Integral Memory

odd thing is you can't really buy this any more there is a bigger model which I plan to get for testing

[JohnAb]

Well I don't understand either, why one reader would work and the other not. No more thoughts on it, sorry, unless the BIOS port doesn't fully support USB 3.0 and above? Not as far as I know, without checking...   

You could try turning off power saving on the internal USB hubs in Device Manager. That can sometimes stabilise the ports when things are plugged in. I've turned that off myself as I have a CFExpress card reader that upsets the keyboard, especially if power saving is enabled.

So far today for testing I have a:

DataTraveler Micro USB Flash Drive

https://www.kingston.com/unitedkingdom/en/usb-flash-drives/datatraveler-micro

Which of course works fine in the BIOS port.

My new SanDisk MobileMate USB 3.0 Reader

https://www.westerndigital.com/products/accessories/sandisk-mobilemate-uhs-i-usb-3-0-microsd-reader-...

Put in a microSD Card in the plug in the BIOS port and it works and can see files in the BIOS for flashing

waiting on other card readers for testing

[PeterUK1]

More testing another Flash Drive Gigastone Z90 32GB USB 3.1
Which of course works fine in the BIOS port.

Now more card readers the bigger integral model USB 3.0 MICRO SD CARD READER
https://www.integralmemory.com/product/usb-3-0-micro-sd-card-reader/
Put in a microSD Card in the plug in the BIOS port and it works and can see files in the BIOS for flashing

next the integral USB2.0 model
https://www.integralmemory.com/product/usb-2-0-micro-sd-card-reader/
Put in a microSD Card in the plug in the BIOS port and it works and can see files in the BIOS for flashing

and a Cablecc Mini Size 5Gbps Super Speed USB 3.0 to Micro SD SDXC TF Card Reader

Cablecc Mini Size 5Gbps Super Speed USB 3.0 to Micro SD SDXC TF Card Reader Adapter Cablecc: Amazon....
Put in a microSD Card in the plug in the BIOS port and it works and can see files in the BIOS for flashing

and I'm waiting for another type of Kingston the MobileLite Plus (MLPM) microSD Card Reader USB 3.1 but I think we can guess this will work.

So Asus why when it did once work in the BIOS port but works fine in any other port this model stopped working in the BIOS port?

I think the whole only Flash Drives work in BIOS port is just a cheap way out.

[JohnAb]

Well,  you now have plenty of Micro SD card readers 😂

[PeterUK1]

Well Asus got back to me and we have not a clue why it stopped working short from me downgrading the BIOS.

From tests I have done we know

It will not work plugged into any USB3 port even on another broad

IT WILL work on another broad with USB2 ports

IT WILL work when in a USB3 port when connected to a dock used for a TP-Link Wifi

makes no sense does it....
