@erkanb-
Sorry, Roku has quit manufacturing the WR001 Long Range Wireless Receiver, and is no longer stocking replacements. The WR002 that replaced it in later Streaming Stick models has a USB-micro connector, not USB-mini, and its electronics are not compatible with the Roku 3810 anyhow.
Paging Roku employees @RokuAustin, @RokuMaryEF, @RokuCarly, and any other moderators to see if they can do anything for @erkanb .
