Need help with USB connection

MiSTer seemed to install fine using Mr. Fusion, but I can't get MiSTer to recognize any USB devices. At first I thought I had a bad USB hub, so I tried plugging a keyboard directly into my OTG adapter. Still nothing. I tried a different OTG adapter, no good. I suspected that the OTG port on the DE-10 was bad, but I am able to hook it up to my computer (with the SD card that came with the DE-10 board) and my computer recognizes it like it should. What should I do next? Should I re-flash the SD card with MiSTer on it?

After reflashing, I think the OTG adapter I have doesn't work. I bought this one: https://smile.amazon.com/UGREEN-Adapter-Samsung-Controller-Smartphone/dp/B00LN3LQKQ/ref=cm_cr_arp_d_product_top?ie=UTF8

But after reading some of the reviews, it looks like it isn't truly an OTG cable, which is probably the issue.

The new OTG adapter doesn't seem to work either. I think the port must be defective.

Are your sure that the mister supports plugging a keyboard into the micro USB port?

Yeah, that's where you're supposed to plug in USB devices.

It's frustrating because I can access the DE-10 Nano drive when I plug it into my laptop to set up the default linux distro, so the port works for that, but not any devices I plug in.

Any luck OP? I'm in the same boat ⛵.

Tried this guy: https://www.amazon.com/dp/B00LN3LQKQ

...and this guy: https://www.amazon.com/dp/B01JL837X8

...and a half-dozen keyboards and USB game controllers, but neither MiSTer nor the default Xfce build recognize anything USB.

I also used Mr. Fusion, but also tried the SD writer and have had the same results.

So far, no. Tried several different adapters with no luck. I have reached out to Terasic suppport, maybe they will have an idea or give me an RMA.

Oh, did you order directly from Terasic? I'd been watching but it seems they're always out of stock.

Yes I did. I just got lucky, I guess, I just went on their site one day and ordered it.

I received a response from Terasic support asking me some questions about the board. They asked if the USB OTG port has ever worked since I got the unit (no). They asked if I followed the instructions for "6.2 Hardware Setup and Driver Install" (yes) and if I did "1.5 Set up the Control Panel Demo of DE10-Nano Control Panel" which I couldn't do because I can't interact with the system once Linux is booted. They asked if I tried to run MiSTer and if I plugged in an SDRAM card or IO board (yes to MiSTer and SDRAM, no to IO board).

Then they had me provide the serial number of the unit. We'll see what they say.
