Flashing speed #33

Hello! First, thank you for the useful tool!

I use CH582 my FW is about 200kB. With the WchIspStudio the FW is downloaded for few seconds. With the wchisp tool the FW is downloaded for a minute. OS: Windows. Version: 0.2.2

I wondering is there a way to increase the flashing speed?

It is caused by the libUSB timeout setting. I did some tests. macOS, Windows, and Linux handle libUSB package timeout in different ways. So the flashing speed can be optimized. I need more investigate on different Chips & OS.
