A patch has been applied to the USB device identified by VID_FFFF and PID_1201 . The device in question utilizes a modified firmware binary
Some CH341 programmers can be re-flashed with stock firmware using a tool like CH341PARA_EEPROM . This removes the FFFF:1201 ID and restores the original (e.g., 1A86:7523 for CH340). – it can brick the device. Device Identification & Hardware Details sudo lsusb -v
Here is a detailed technical breakdown of what this device is, why the ID is unusual, and what "patched" refers to in this context.
Or better, correct the underlying issue by using spice or virt-viewer with USB redirection.
