Does anyone know more about this?
Is the USB IC enabled WITH the resistor? Or WITHOUT it?
No I don't know about it.

But mine came without the restitor. It said it s a special switch edition. No problem at all using it in my switch. Never crashed and never failed
I guess it s more stable without it

Do you need to be in Horizon to be able to update it?
Because I get conflicting reports how to do it exactly.

Here is a video of the creator of this modchip and he says to turn the switch completely off and THEN update it ?
How he is doing it, is beyond me, because the chip won't get any power if the Switch is powered off doesn't it?

If you don't already have switchboot on your chip, download the correct uf2 AND switchboot.bin...

Get console into RCM mode, push "switchboot.bin"... Using tegrarcmsmash or whatever...

On the menu, you will see samd21 update mode. Select that, follow on screen instructions

I see and did you figure out the USB IC enable thingy? Is the IC enabled with oder without that resistor?

Not looked yet. Not been too well lately, hence my lack of posts this past few days.

But I forgot I had built v1.3.3. (yes really) do thought I'd upload it.

I'll look this afternoon

I have a magnetic switch on it. So I can upgrade the chip in horizon and rcm. Just double reset with a small magnet and done.

But I m gonna try the switchboot method soon. Sounds easier. I love that mod. Thanks op :-*

I hope you are feeling better.

Thank you for your effort trying to help us with the RCMX86 usb problem.

I thought modchips can't update in RCM because because there are no USB comms at this point. At least that's what the SwitchMe github says.

i have update to the newest versin from switchboot 1.3.3 but i think
it shows not so good.
For Example i have the new option: "3. Re-Insert SD Card.
Dont boot from ini E Option again and continue.
 
Hmmm...

Not too sure what you mean sir. Any chance of a screenshot?

I`ve probably messed something up. Not been on top form lately...

Here we are. If someone wants to ty this...

Remove USB logic chip (red cross)

Join new wires to green and yellow points.

See if it fixes RCMX86 issues?

Code:
// More parts to backup that do not currently fit the sd card free space or fatal error.
                if (currPartIdx >= maxSplitParts)
                {
                    gfx_puts("\n\n1. Press any key to unmount SD Card.\n\
                        2. Remove SD Card and move files to free space.\n\
                           Don\'t move the partial.idx file!\n\
                        3. Re-insert SD Card.\n\
                        4. Select the SAME option again to continue.\n");
                    gfx_con.fntsz = 16;

                    return 1;
                }

Is there enough space on SD card? That part of code hasn`t been touched. Puzzled.

yes have get back to 1.3.2 and a looks fine.
will try it when im at home in the next 2 days and i write to you ;)
 
It's the usb logic chip that's doing it. Notice how rcmx86 inject slower than a rebug or trinket

Finally I think I found the RCMX86 usb problem, at least in my case.
I think it was the magnetic reed that was close to the switch fan and its magnet and was causing problems with GND.
I moved it a little bit down and it's working properly, no more problems with usb.
 
Fantastic. The coils in the fan probably cause problems. Leading to partial current flow to the SAMD reset controller. That never occurred to me. I don`t use reed switches... I fit a "trinket" SMD one
