Driver fault

[PLENTY]

Hello. I'm using Ubuntu 18.04.3 LTS. I'm trying to get my JT308 RFID
reader working. Please help.

$ sudo modprobe usbserial vendor=0xffff product=0x0035
$ dmesg
...

driver is only for testing and one-off prototypes.
[  266.304579] usbserial_generic 2-1.5:1.1: Tell
linux-usb@vger.kernel.org to add your device to a proper driver.

$ lsusb -d ffff:0035 -v

Your RFID reader does not have interfaces for a serial driver, the 
interfaces are for a HID driver.
Your verbose lsusb listing would have showed that had you not cut it 
short and your dmesg should also show a HID driver attempting to bind.
