when appear Fail open usb devices, can you check if there are "usb download devices" at zadig?

Did you use bz2 as rootfs?

It should not related your windows environment. The decompress was done at boards. Maybe boards was out memory and kill tar by linux. can you try drain some file system...

Yes, suppose all transferred's data should be the same between linux and windows. Maybe wireshark trace some usb packages to help diagnosis. Try clean cache firstly.

what's size of your emmc chip?

I am not sure. Can you shared your image?

Do you have ffu format spec? Your file dwDiskAccessMethod using 1 and 9, which is not supportted yet. I supposed 1 is from current, not sure what's 9 means. typedef...
