What are you using to access the device? It seems to be designed around Chrome, perhaps if you're using a more niche browser that could be the issue? Or have you checked the cables on other devices to make sure they're not power-only (I know many of mine are, luckily I've got one of these to test my own cables)?
Thanks for helping. That wasnt a bad guess, I should have tried other browsers first. Anyway I just did try with Chrome Brave and Firefox on both Linux and Windows, still exactly the same problems: no keyboard/mouse output, Press Failed when triggering the fingerbot, but I have HDMI just fine.
Regarding the cable, I use it for hard drives so it cant be that.
Regarding the fingerbot, the display on the page only indicates that the dongle has been detected. However, if the fingerbot is too far away, it will indeed fail.
Regarding the issue of the keyboard and mouse not working, your testing indicates a conclusion: your controlled computer does not support having two mice on a single USB device. Before version 1.4, we only emulated one mouse, but after version 1.4, we started emulating two mice simultaneously.To avoid the need to restart the device when switching mouse modes.
I guess you tested multiple different systems, such as WIN/LINUX/BIOS/EFI, all on the same computer, right? This issue typically occurs on very old computers, even older than platforms like B75.
Regarding the Fingerbot, I suspect you might have received a product with antenna issues. If you're certain it works only when placed very close or it just completely not working at all, I recommend you initiate an RMA
Regarding the issue with multiple mice. Let me see if I can provide a command for you to disable the other mouse.
My issue was finally fixed, the inputs fixed themselves out of nowhere (no cable change nothing) and a new fingerbot works perfectly. Thanks for your help !
