Default Booting from USB3.0 PCI-E card?

I have an ASUS M2N-E motherboard which seems to have no working USB ports. I don't know if the USB chip(?) is dead or if it's a BIOS problem.

Of course, these boards update the BIOS using a USB Thumbdrive.

So the question is do I buy a USB3.0 PCI-E card that installs into a 1x or 4x PCI-E slot and costs $15 or do I buy a new BIOS chip which is about $20.

If the USB3.0 card does not boot the board I can use it on another board. If I buy the BIOS chip and this doesn't fix the USB functioning, it's a loss.

Has anyone successfully booted from a USB PCI-E card?

nope. this being a nvidia shitset bumpgate board, its probably the mcp sb that is fucked. thats why the usb ports are no worky. u can ask momaka on how to do a ufc mma punch on the mcp to temporarily fix it and get the usb ports useable albeit temporarily. he has done this kind of ufc punch fixes before on these dying nvidia shitset boards.

or try reflowing the mcp sb. see if that fixes the usb ports.

you put a spare harddrive on another machine and install freedos on it together with the bios and flasher - then plug it into the asus board.
it's not your bios though.

boot a Linux live-disk from dvd,
then try to scan or access the usb ports - linux does not use the bios.

Lol.
My method has only been successful on this one ECS MCP61PM-AM motherboard (from a Gateway GT-5656 PC), so far.

USB still works after those punches and board seems to be stable overall.

That said, I also give that PC regular kicks too, now - not because there are problems with it, but because it's under my desk and I often conveniently use it as a foot rest. The nice curves on the GT-5656 case make for a great foot rest, actually.

On a related note, I do also have an Asus/Pegatron M2N-E (or similar M/N anyways) motherboard from an HP Pavilion PC that locks up in BIOS with any SATA devices attached to it. No SATA devices and I can boot. Very likely I suspect the issue is with the GeForce 6150 / nVidia MCP61 chipset there.

So I think Chaos may be onto something here - your board may have chipset issues. Try the live Linux boot DVD, as sjt suggested, to see if you can access the USB ports (though also check in CMOS that they aren't disabled.) If that doesn't work, then maybe try the USB 3.0 PCI-E card method (though keep in mind that a failed MCP61 chipset can also have issues over PCI and PCI-E slots), as this will at least allow you to reuse the card in another PC.

In any case, don't invest too much into that M2N-E motherboard, IMO. Unless you make modifications to the chipset cooling (at least add a 40 mm fan once you determine if/where the issue was and that it wasn't from the chipset itself), the board will likely die from chipset issues, eventually. There really should have been a class-action lawsuit against nVidia on these, because way too many had issues.

Thanks everyone for your suggestions. I'm going to use an old 10GB IDE HDD and the Freedos method to update the BIOS.

So I just boot a Linux disc and do a LSUSB command to see if the device is found?

If LSUSB detects it then what?

If the USB3.0 card lets me use a USB keyboard and mouse, I will be satisfied.

I know VIA cards are no good for Linux (not recognized)

I have a heat gun and a handheld digital temperature reader. Any tips on a ghetto reflow?

Is this a soldering issue or the chipset itself degrades and loses functionality?

Thanks for your patience.

i doubt that, Linux has newer drivers than windows.

I made multiple mistakes trying to update the BIOS on the board with the dead USB ports. I burned the FREEDOS img file fo a USB stick, then copied this plus the other FREEDOS files plus AWDFLASH and the 5001.BIN Bios file to the IDE HDD. This would not boot. The USB ports had miraculously come back to life, so I tried the USB stick I was able to flash the BIOS successfully,restart and edit the BIOS via the DEL key, but when I restarted the board it would not boot the OS.

I removed the BIOS chip from the board and put it into my good board. Same results. So I tried the onboard EZYFLASH2 option. It wanted a CD, so I burned the 3001 bios version to a CD and was able to repair the BIOS.

i personally wouldnt trust that chip too much - consider a new one, blanks are only a $ these days.

No boot rom = no support. At least for the PCI/PCI-E storage controllers.
I have never investigated a boot from a PCI/PCIE USB card.
The bios must recognize the controller, so it can use it as a valid device from which it can boot.
