Hello,

I've got this problem that when a connect an USB device it starts disconnecting like crazy. I've tried selective suspending but it doesn't work.
So, after many reinstalls of Windows 10, I found when the issue starts.

Just after I install the Nvidia drivers, the Usb's starts disconnecting. If I unistall the Nvidia driver, the issue is gone.
With the driver uninstalled, if I connect AGA, the issue gets back even with the driver uninstalled.

Now, all of this is with the A10 bios. If I install A08 bios, when I install the Nvidia driver, USB's work fine. But if I connect AGA, Usb's start disconnecting again but not so often, so I guess that it is more stable?

Dunno if ME is the problem, but a while ago I remember I updated to A05 or A06, and the issue started, and I remember that while using dell bios utility, a cmd window popped up stating that was flashing ME. This happens also with A10.
ME shows up fine in HWinfo.



I'm attaching the bios region of A10 and A08.

Thanks in advance!

Update:

I managed to modify the A08 bios with AMIBCP5.02, by changing the optimized defaults.
I disabled the iGPU, ran windows again with AGA attached and I still got usb disconnecting but only on some tipe of USB devices (Webcam in my case).



So I connected the webcam with a USB 3.0 hub with an external PSU and the device works!

Now the problem is that I'm stuck without the iGPU cuz I dunno how to enable the hidden menu in dell bios.
Can someone help me to unlock the A08 bios?

Thanks!

@Lost_N_BIOS sorry to summon you like this. I've read that you can unlock dell bioses, can you unlock mine?
Many thanks

@ViolentKain - Flash A10 BIOS, and send me FPT BIOS region dump, then I will send back unlocked BIOS. Obviously leave out this USB Device until we are done
This is not normal error for A10 BIOS, so must be something going bad on your board like USB Fuse, or whatever USB device is not compatible for some reason (or it's going bad, shorting etc)

Sure. It would be amazing if we can fix the usb problem as it happens also in the Usb ports on AGA, so all the ports does this.

I'm adding A10 biosreg also, can you unlock A08 biosreg too? Just in case.

Thanks!

@ViolentKain - Sorry, not sure what USB Ports on AGA means? Yes, I could unlock A08 too, but do you really need it, or is unlocked A10 going to be OK? It's OK, I will do both
I can do A12 too, sorry, I didn't realize before that A10 wasn't latest BIOS. If you want unlocked A12 too, flash it normally, then dump BIOS region with FPT and send to me too.
Here is unlocked A08 + A10, flash back via >> FPTw.exe -bios -f filename.bin

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user ViolentKain at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not ViolentKain, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

Awesome! Many thanks!
AGA = Alienware Graphics Amplifier.

I'll check the Usb ports with the multimeter this afternoon, I'll see if I can find anything wrong. Any suggestion of what should I focus?

Also, here's A12 biosreg.

Then again, thanks!

You're welcome! Ahh, AWG, thanks

Sorry, not sure what to check for with USB, probably newer BIOS may have different way of checking the fuse allowances and maybe tries to disable them if they are weak, when old BIOS did not do this.
That is all i can think of, especially since USB Still works, so we know fuses aren't blown out.

Here is unlocked A12

I've been doing research and I found something interesting.
A08 comes with some pre-loaded config (before you load optimized defaults), which are the ones that I think makes the USB work ok.
But somehow if I try to change that config, save and get back into the bios, it doesn't work, the values won't change in those specific options.

@Lost_N_BIOS Do you know why?

There's LOTs of settings there, you need to be more specific. Plus those images are not comparing same thing, and I have no idea what image is what BIOS either.
I can change any BIOS setting, as can you now, what specifically are you not able to change?

Before you load optimal defaults would = Fail safe defaults, and once you load optimal on A08 those would not be used anymore, only optimal would, and you said A08 works so assume optimal A08 works.
So apply same same on both A08 and A12 and it should work, provided that is the issue

It is the same page in A08 bios, the path is Chipset > PCH-IO Configuration > USB Configuration

So in A08 I've found that config.
The exact changes are:

XHCI Mode - Manual
Route USB 2.0 pins to which HC? - Route Per-Pin
USB 2.0 PIN #0 - Route to XHCI
USB 2.0 PIN #1 - Route to EHCI
USB 2.0 PIN #2 - Route to XHCI
USB 2.0 PIN #3 - Route to XHCI
USB 2.0 PIN #4 - Route to XHCI
USB 2.0 PIN #5 - Route to XHCI
USB 2.0 PIN #6 - Route to XHCI
USB 2.0 PIN #7 - Route to XHCI
USB 2.0 PIN #8 - Route to XHCI
USB 2.0 PIN #9 - Route to EHCI
USB 2.0 PIN #10 - Route to XHCI
USB 2.0 PIN #11 - Route to XHCI
USB 2.0 PIN #12 - Route to XHCI
USB 2.0 PIN #13 - Route to XHCI

Enable USB 3.0 pins - Select Per-Pin
USB 3.0 PIN #1 - Enabled
USB 3.0 PIN #2 - Disabled
USB 3.0 PIN #3 - Enabled
USB 3.0 PIN #4 - Enabled
USB 3.0 PIN #5 - Enabled
USB 3.0 PIN #6 - Disabled


On A10 the config is like this:

XHCI Mode - Smart Auto

The pins setup doesn't show up until you change it into manual.
But even if you change it into manual, when you save and exit, and enter again to the Bios, the changes in that specific option and under, it reverts into Smart Auto.

So do you need edit, and if yes, what changes?
