USB Adapter RD9700 not showing up on ifconfig or ip addr or ip link

The WiFi adapter works fine on Windows because CD-ROM pops up with appropriate drivers when it's plugged in. But on Arch Linux the driver doesn't show up as a network interface, but the device is recognized. I've tried modprobe'ing sr9700, dm9601 and installed usb_modeswitch and did whatever I could find relating to those but nothing works. The adapter Model No. is ky-rd9700-22

I don't get how it works, like the device is recognized by the kernel as 10/100 Ethernet Adapter, but the NIC is not shown.

I think the situation is still the same as described in https://www.draisberghof.de/usb_modeswi … eek#p14609 in that neither of the modules you loaded will match the 9702 so you will need to modify and rebuild the kernel
