I purchased a Geekworm x680 in July 2024 so I assume it is v1.5. Using it with a CM4 without eMMC, and with a MicroSD card. Everything works except for the Mass Storage Device feature. Anyone else having this problem?

I installed the latest pikvm, then updated it (to KVMD 4.3).   I have two PC's connected to the x680.

I've tried Windows 10 install iso, several ubuntu desktop iso, system rescue cd iso, clonezilla, freedos, Windows 10 installer iso in a Ventoy image, etc. but none that the PC BIOS or Windows 10 PC, or Ubuntu PC can recognize. My PC's do not see it at all.  I've tried CDROM and FLASH modes, toggling the Connect Main USB to server, but does not work.  

I've tried the procedure @Harry Huang suggested: made a bootable Windows 10 installer on an 8GB flash drive using Windows Media Creation Tool app, verified it works by plugging in to the USB HUB Of X680 and verified that my PC's can see it on BIOS, Windows 10, and Ubuntu - that works great.    Then I used dd to make a file from the working 8GB flash drive, upload and clicked "connect drive to server" on pikvm, I tried scp the file to the CM4 directly too, but it does not work.
