They are dammy pins. Another dead-end

Dated reply I know, but for person having that issue having the USB not working.

I have two rs90 and both would not work at all on my dell e7440 laptop windows 10, button combos, cable changes nothing.  For the heck of it, i tested on another laptop, dell 6440 (my GFs laptop) with windows 10, same cables and all.  Holding A, device popped right up zero issues... both actually.  Got the CFW flashed and everything working perfectly.

What i'm saying is its quite possibly not your cable and just your laptop... i'm not sure why at all... all other USB devices work perfectly fine on my laptop.

Good luck.

EDIT: Figured it out... go to device manager... put your USB Hubs OFF power management.  Mine worked perfectly after that.

EDIT2: Also noticed if you don't need direct USB access, the 5/17 cfw works faster (more instability) than the 6/1 or the 1/6 cfw.  I have all three in my internal memory so i can swap back and forth if need be.  All my emus/roms are in my SD card.  I'm amazed how well PCE and PCE-CD run on this unit... GBA works amazing as well.  Picodrive is close, extremely playable... MegaCD titles are a tad choppy (sonic CD runs about 45-50fps @ 436mhz overclock).  Both my units are left at 5/17 fw (regba, picodrive, and temper all seem very stable... apps like doom forget about it... instant crash).

Amazing work for all involved.  Unit went from a subpar GBA emulator only to an amazing GBA device... add in full speed PCE (PCE-CD) is amazing... megadrive run well as well.  Rest of the emulators I tested didn't run very well (or I'm not too interested in the console/system, although gngeo would be amazing... i think the resolution would be an issue though.  That said PCE-CD has fatal fury special and art of fighting which runs amazing.

I found an external SD card reader and was able to transfer files to my sd card.  All the files are still on the SD card and it's FAT32.  I will leave the post to possibly help someone else.

Thank you very much! I followed the tutorial as it was and I was able to install OpenDingux Beta without any problem from Window 10. The truth is that it is a significant improvement over the previous custom firmware that I had installed. Now I just have to expand the number of functional emulators, the ones you provide, temper, Handy and megadrive works fine, Prosystem and Oswam a little worse. Waiting for Gameboy, Advance, Nes, Snes... etc...

Thank you very much gameblabla for your work and your time. Greetings from Cadiz (Spain)

Get the latest build from here: https://github.com/OpenDingux/buildroot/actions?query=branch%3Aopendingux+

The JZ4725B does report itself as a JZ4750 over USB (they are almost the same thing).

I do not see any downloads, am I missing something obvious?

Ok, so I clicked the "get the latest build from here" link. Opens a "all workflows" page. Clicked "CI: save/restore ccache folders". Scrolled down to "Artifacts". None are clickable/downloadable (ex. update-rs90 34.8 MB). Tried a few older flows, some have a "expired" tag next to the artifacts, I'm guessing that means they were downloadable at some point.

Looks like you need an account, yes. Sorry, I didn't know that.
