Bought 2 one by one. At the first usb port fell into the case and he did not see the walkie-talkie, he thought it was a marriage. I bought a second one, it was stronger, but still did not work. Began to search somehow found that I need another less common driver. Along with the goods there was a floppy disk with the necessary drivers, but the cd drive is hard to find now) Just in case: drivers for WCH chipset, CH341SER came up to me
