Expand description

Returns a list of connected devices’ id’s, delimited by ‘;’ character. Empty string is returned on no device found. Each ID could consist of:

  1. SC_id:SD_id_p_path (about 40 bytes)
  2. path (about 10 bytes) where ‘path’ is USB path (bus:num), ‘SC_id’ is smartcard ID, ‘SD_id’ is storage card ID and ‘p’ and ‘:’ are field delimiters. Case 2 (USB path only) is used, when the device cannot be asked about its status data (e.g. during a long operation, like clearing SD card. Internally connects to all available devices and creates a map between ids and connection objects. Side effects: changes active device to last detected Storage device. Storage only @example Example of returned data: ‘00005d19:dacc2cb4_p_0001:0010:02;000037c7:4cf12445_p_0001:000f:02;0001:000c:02’ @return string delimited id’s of connected devices
