Hello there, this is my first post here (& ever on berilos), sorry for
any inconvenience & ignorance...
I have this cellphone whose camera can work as UVC device (at least in
windows it does). Have been playing a bit with uvcvideo driver, but this
camera doesn't seem to be supported (tried builds 141 & 147)...
Thank you for all UVC supporting efforts!
Btw, what is the meaning of 'Failed to initialize the device (-5).' ?
here's dmesg info;
