It does seem a version regression of the recent ASMEDIA XHCI Firmware Upgrade Tool v0.2.0.5 compared to the v0.2.2.0 which is was available on 14th July 2018 ?

Fix offered on station-drivers to update to 1507_30_02_1F firmware version.

Do use ASM2142ASM114xFWUpdate.exe command under the unzipped folder.

Just as a report for anyone trying to update their firmware on the ASUS Maximus VII Formule (Z97):
It's using an ASM1042A (should be the only variant used AFAIK) and I was able to update the firmware successfully with the version of the firmware and 104xfwdl.exe linked in this thread for the ASUS Crosshair V:
[OFFER] Asus Crosshair V Formula 1703 mod BIOS
"ASM-1042A Firmware v140124_10_10_04"
Updated CFG with what I got from 104xfwdl.exe /D
//SVID=0x1043 // System Vendor ID
//SSID=0x85fd // Subsystem ID

Thanks for everyone providing information here, as well!

Today I found out my USB 3 port by ASM1074 seems a bit choppy on performance
My Motherboard is Asus Vanguard B85
So I did to downgrade the current firmware from 14041503E500 to 13031903030EV1
But unfortunately I accidently terminate the firmware upgrade process when it was upgrading.due to the program got stuck and hanging long time
What can I do to restore two USB 3 port back on working states?

Does anyone know how to reflash the ASM1074 (ASM107X) firmware,Can I use the 104x tools for flashing?
because my update was failure due to downgrading the firmware.And the Bios aswell as the Devices manager cannot recognize the usb,Even it has power of it...
what I could do?

Get a flash programmer, and then program back in the original FW. You may need someone with same board to dump chip from their board too.
Someone might be able to help you fix it from the other thread, unsure if that's possible without a programmer though, maybe you will get lucky.

If you run the 114041503E500 FW Update package, does it detect your chip?

So I did to downgrade the current firmware from 14041503E500 to 13031903030EV1
But unfortunately I accidently terminate the firmware upgrade process when it was processing.due to the program got stuck at 70% and hanging for a long time
After that,I can't make it work again no matter on Bios or Reflash on windows...
What can I do to restore two 2USB 3.0 port back of my motherboard on working states again?

Thanks for that,But does there has any tools I could use for fixing this problem...
Can I flash it thought other tools like flashrom in linux???
Because I don't know where does the firmware of ASM1074 stored.
