(Solved) Hello. I solved the problem as follows; 1- I created a file named "disable_usb3.conf" in the "/etc/modprobe.d/" directory. 2- I added the line "options xhci_hcd no_usb3=1" to the file and saved it. 3- I restarted the system.
After the above steps, I plugged in the USB external disk. When I checked with "lsusb -t", the external disk speed was still 5000M. I changed the ports where the mouse dongle and external disk were plugged in. Result; "Class=Mass Storage, Driver=usb-storage, 480M" I started the process of copying a large file from the external disk to the local disk. I tried the mouse from far distances. The result was successful.
