The product was delivered fast and in good condition for a good price. But as i wanted to use it and plugged the board into my computer, Windows 10 showed me a message the device wouldn't work properly. After hours of research i found out that some time ago, FTDI, the manufacterer of the chip on that board, had problems with counterfeit chips from other companies. FTDI took countermeasures against the fake parts by identifying the fake chip using their driver software and rewrite the usb identification codes (VID and PID) of the chip to 0. With an ID of 0, any operating system will reject the chip rendering it useless. Only driver versions 2.11.00 later are affected by this, versions 2.10.00 earlier are clear. NOTE: FTDI drivers have been removed from Windows auto update. So if you're lucky to have 2.10.00 earlier, you won't get the corrupted software. Sadly, old driver versions are unavailable for manual installing on their website. The problem with these counterfeit chips is that one can't distinguish it from an original. So most often even the seller of a product, in this case Bangood, doesn't even know they're selling fake chips because there is a possibility that somewhere in the supply chain of the manufacterer of the board, someone decided to by parts from a different supplier because others were out of stock or a lot cheaper than others. I bought an FTDI board on Bangood some time ago which still works just fine: https://www.banggood.com/de/3_3V-or-5_5V-USB-Programming-Module-for-Naze-Minim-OSD-Frsky-Multi-wii-p-1010726.html?rmmds=search&stayold=1&cur_warehouse=CN Later, i needed some more and ordered again without noticing i had chosen a different item: https://www.banggood.com/de/FTDI-5V-USB-To-TTL-MWC-Universal-Programmer-Debuger-For-Arduino-FIOprominiNWC-OSD-MINIOSD-F3-p-1173299.html?rmmds=search&stayold=1&cur_warehouse=CN The items looked the same and were sold for the same price with the difference that one works the other doesn't. However, there is a small chance that with the next resupply, fake chips also have sneaked in. I was able to repair the modules by replacing the counterfeit chips with parts i bought from Mouser Electronics: https://eu.mouser.com/ProductDetail/FTDI/FT232RL-REEL?qs=sGAEpiMZZMs5ceO8zL%252bTxyQLQIH6hE7q I do not recommend this method for the end-user because it requieres a fair amount of soldering skills and the new chip is almost as expensive as the whole module (+shipping).
