Hello, I hg cloned, compiled and installed successfully:
" sudo ./loader Searching for device... Found camera : 05ca:1810 Firmware : ucode/r5u87x-05ca-1810.fw
Camera reports negative microcode state. Sending microcode to camera... Enabled microcode. Camera reports microcode version 0x0115.
Successfully uploaded firmware to device 05ca:1810! "
I opened Skype, but video is corrupted as in attachment.
Thank you for your work!
