Windows USB Driver ================== You don't need to install a USB driver unless your hardware is controlled by USB. If you have recent SoftRock hardware controlled by USB, you must install a USB driver. Quisk uses the same driver as other SoftRock programs, namely the PE0FKO driver package. This driver is based on libusb-win32, which in turn is based on libusb-0.1. http://home.ict.nl/~fredkrom/pe0fko/SR-V9-Si570/#install A newer version of libusb called libusb-1.0 will soon be available, and the SoftRock community may start using the newer software and a newer driver. Quisk will always follow any changes the SoftRock community makes, so just install whatever libusb driver is most current. If it doesn't work with Quisk, I will fix Quisk.
