Re: [Ftdi-usb-sio-devel] New FTDI driver for a FT232R module.

[Allen, M. <al...@ul...>]

Me from my normal work email:

I've narrowed down what the problem is. When I modprobe ftdi_sio with
"vendor=3D0x16ff and PID=3D0x0080"(which are the correct VID and PID for =
our
new device) it works just fine. So it seems that something is going
wrong with the probing or the hand off with the serial subsystem.

Subject: [Ftdi-usb-sio-devel] New FTDI driver for a FT232R module.

Hello, I've recently been hired to work on a "custom"
driver for a USB-Serial device that we have here. The
device is using the TTL-232R USB - TTL Level Serial
converter with the FT232RQ chipset.

We're using linux 2.6.16 for the development platform.
We've got our own VID and PID but I'm having problems
adapting the FTDI_SIO drivers found in the 2.6.16
kernel to work. When I plug in the new serial device
it seems like the USB subsystem gets the device and it
never gets moved up to the usb-serial or to even
further up the FTDI driver.

The last messages in /var/log/messages that I'm
getting are:

Feb  8 16:06:24 r88882-pos02 kernel: usb 6-1:

I figure that it should mention something about
usb-serial or the ftdi_sio modules but nothing. I
checked to make sure they had been insmod'ed and the
drivers are loaded.
