8bitdo Ultimate 2 controller USB dongle keeps disconnecting

I might be able to find a workaround. Stop and exit the virtualhere server then download this test build and let me know if that works

OK great, im glad that worked. The 8Bit do is a bit strange in that it changes its state often so i added a workaround for that.

My VirtualHere server log shows an OPPO device ([22d9:2765]) repeatedly connecting and disconnecting in a loop:

[...repeats continuously...]

The device binds → unexpectedly unbinds (SURPRISE UNBOUND) → reconnects. I’ve already reinstalled the latest VirtualHere server, but the problem persists. Seeking assistance to resolve this.

I’d appreciate any guidance—this loop makes the device unusable through VirtualHere. Thank you! 🙏

Is this related to 8bitdo?

Hi,

I am experiencing the exact same issue as the original poster. I have an 8bitdo Ultimate 2c with a USB dongle. The dongle is connected to an old Surface Pro running Windows 10 and the Virtualhere server; I've tried both the regular Windows server release and the above test build, but the issue persists. My client is on a Windows 11 PC connected to my router by Ethernet, while the server device is over wifi. Appreciate any assistance with this. Thanks in advance.

Edit: Same issue occurs when the controller is connected by its official usb cable to the Surface/Server device.

Try this updated build again:

Fantastic, this works. It no longer disconnects and remains stable. Thanks a lot. Would purchasing a license allow me to connect 2+ dongles simultaneously with the test build?

Probably, however i did get some feedback that two at once didnt work with an Android Server https://www.virtualhere.com/node/4657
