indi_getprop appears to have a problem with the device name that contains either a period or a parenthesis, in this case device "Toupcam EP3CMOS02300KPC(USB2.0)". Is there any workaround, how to use indi_getprop/indi_setprop with this device?
I rewrrote the function crackDPE in file getINDIproperty.c and it works. But it's quick and dirty solution for today's observation without knowledge of other connections to anonother parts of code. Analogous changes need to be made in setINDIproperty.c.
