Samsung E2252 Usb Driver (iPad GENUINE)

You need this driver for three primary reasons:

// Read response byte[] buffer = new byte[1024]; reader.Read(buffer, 2000, out int len);

Send: AT+CPBR=1,10\r\n Read response until OK .

Windows shows “Unknown USB Device (Device Descriptor Request Failed).”
