android - USB-Serial FT232R not detected by Samsung Galaxy S4 -


i trying connect usb-serial accessory samsung galaxy s4 phone. usb device not detected in android os , not in underlying linuxse (according app "usb device info" listing usb devices). usb-serial accessory uses ftdi chip ft232r.

details:
model: samsung galaxy s4
version: gt-i9505
kernel: 3.4.0-526204

usb-serial model ft232r vendorid 0x0403 productid 0x6001

i managed resolve problem. samsung galaxy s4 correctly identifies usb-serial accessory. using usb otg cable resolves issue. usb otg cable needed samsung galaxy s4 in case should host (e.g. supplying power).
