This an issue about GOWIN FPGA

[cinder023]

when i install the driver of GOWIN Programmer , i couldn't find the ttyUSB* in the folder of /dev
if i uninstall the driver of GOWIN Programmer,i could find ttyUSB*
below is the message of running " sudo dmesg "
When I connected the USB to serial cable on the FPGA to the computer, the dmesg message indicated that the interface was recognised for a short time, but then disconnected a split second afterwards
