not automatically detect the USB drivers, download the latest version from here

3.9.2 USB driver configuration
The FDTI drives are set by default with a latency of 16ms instead of 1. This leads to low communication
rates. To decrease this latency, follow the steps below to configure the USB driver:
1. Open Computer Management tool and select Device Manager. Expand Ports (COM & LPT) and double
click on the USB Serial Port (COMx).
2. Click the Port Settings tab and then the Advanced button.
3. Set the Latency Time (ms) to 1 instead of the default value. This will ensure optimal communication with
the drive.
Remark:
The COM port number can be also changed from Advanced Settings dialog
4. Press OK button to complete the configuration of the COM port.
