How to access a FTDI usb device with a custom vendor and product id's

[Burton Sampley]

Ian,

Thank you for your prompt reply.

Looking at the usbdevs file, I found 0x2100, but there is no entry for
0x9e56, which is my device.  So, I'm assuming that changing uftdi.c to the
correct name for the VID will only solve part of my problem.  I will
further assume that I need to find the correct/proper entry for usbdevs as
well.  Is this a correct assumption?  If so, then how/where can I find the
proper entry for usbdevs?

Here's the 2 closest entries:

/* RT system products */
product RTSYSTEMS CT29B         0x9e54  FTDI compatible adapter
product RTSYSTEMS SERIAL_VX7            0x9e52  FTDI compatible adapter

For me, what appears to be the last piece of the puzzle is to find the
correct name to place in the 3rd field.  Based on the following:

$ /usr/local/bin/sudo /usr/sbin/usbconfig -d ugen2.3 dump_device_desc
ugen2.3: <CT-62B Radio Cable RT Systems> at usbus2, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=ON (90mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0008
  idVendor = 0x2100
  idProduct = 0x9e56
  bcdDevice = 0x0600
  iManufacturer = 0x0001  <RT Systems>
  iProduct = 0x0002  <CT-62B Radio Cable>
  iSerialNumber = 0x0003  <RTUI129S>
  bNumConfigurations = 0x0001

$

does "CT-62B" look reasonable?
