Matwey,
lsusb -v shows
idVendor 0x0403 Future Technology Devices International, Ltd
whereas idProduct is
0x6001 FT232 Serial (UART) IC
Is this the information you were asking for?
Yes, this is the correct information. This device is supported by the
Linux ftdi_sio driver. Specifically, ftdi_sio.c contains
{ USB_DEVICE(FTDI_VID, FTDI_8U232AM_PID) },
Which are defined in ftdi_sio_ids.h as
#define FTDI_VID 0x0403 /* Vendor Id */
#define FTDI_8U232AM_PID 0x6001 /* Similar device to SIO above */
Try the following to debug:
* What are the system logs when plugging in the device?
* Also do a "ls -lt /dev | head" after plugging in the device
* Build a loop back cable and run a program like minicom

What is your vendorid/deviceid pair? It may be read using lsusb
command line tool.
Probably ftdi_sio has your pair missed in its table.
