[gentoo-amd64] USB-Serial Converter?

[gentoo-amd64] USB-Serial Converter?

[Peter Davoust]

[-- Attachment #1: Type: text/plain, Size: 1149 bytes --]

I'm very new to list servs, so I don't really know if I'm going about this
the right way, but I can't really find my USB-serial converter in /dev, and
I would appreciate if someone could tell me where I might find it. I'm using
an FTDI rs-232 to usb converter, and I installed the driver from their site.
I tried

echo "test" >> /dev/ttyS0 and the light on the dongle didn't blink, which it
does when there's data traveling through it. I tried that with
/dev/ttyS0-4.  /proc/bus/usb/devices gives me this, among other things:


T:  Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0403 ProdID=6001 Rev= 4.00
S:  Manufacturer=FTDI
S:  Product=USB HS SERIAL CONVERTER
S:  SerialNumber=FTCTXW5O
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr= 44mA

E:  Ad=81(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=02(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms

I basically just need to open the device as a file in either C++ or Java and
write to/read from it. If I'm going about this the wrong way, please let me
know.

Thanks,
-Peter

I've got two of them - they're on /dev/ttyUSB0 and 1.  The biggest pain
for me was getting them to show up on a particular port all of the time.
 I managed to do this by tweaking the hotplug config to be dependent on
what USB port the device was plugged into.

You do need to have the appropriate kernel drivers enabled.

Hmmmm.... I see no ttyUSB when I do ls /dev/tty*. Is there anywhere else it
could be?

Check dmesg when you plug it in - is it detected?

Try checking out lsusb - can you figure out what driver is needed?

Make sure you have CONFIG_USB_SERIAL set in your kernel.  You probably
also need the appropriate driver for your adapter.  I have PL2303 set
for mine.  Here is my lsusb output for the serial ports:

Bus 002 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial
Port
Bus 002 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial
Port

If the kernel doesn't have USB_SERIAL support enabled you definitely
won't get a ttyUSB device.  You also need hotplug properly configured,
but that should pretty-much work out of the box with gentoo.  You might
need to tweak it if you have more than one and want to ensure it gets
the same port each time (wouldn't do to have my two mythtv satellite
boxes getting random assignments every time I reboot).

It's device 008 on bus 003. I tried /dev/bus/003/008, and got nothing. Any
more ideas?

What is the actual output of dmesg after plugging it in (just the last
few relevant lines)?  How about the output of lsusb (emerge usbutils)?
Also, what is the output of grep USB /usr/src/linux/.config (assuming
you built your own kernel)?  And, for that matter, what is the output of
lsmod (in case support is in an unloaded module)?

Hotplug is obviously not creating a device for the adapter - it is
probably because the kernel isn't recognizing it.  That is likely the
result of support not being compiled in, or it being compiled into a
module that isn't loaded.  Failing that it could be a hotplug issue - we
can work around that using mknod to create a device with major,minor
188,0.  If that works then you have a hotplug issue.  However, I think
that isn't the most likely problem.

This is not exactly what is needed. Basically the easiest thing is to unplug 
the device. Do a dmesg. Plug the device. Do a dmesg. The new lines are 
interesting. I think however that the others are right that you don't have 
the proper driver in your kernel. As you say that you have a driver 
available, make sure that this module is loaded / compiled into your kernel 
before pluggin in the device.

A quick check of google tells me that CONFIG_USB_SERIAL_FTDI_SIO=Y needs
tyo be set in the kernel for this device to work.  Rebuild your kernel
with this support and try it.

Actually, the output he sent is exactly what you get if you don't have a
driver installed.  It just states that a device was plugged in and
nothing more.  If you have a driver then it gives you a bit more output.

The other post seems right - if make menuconfig is being used look under
the USB settings where USB serial support is enabled, and there will be
a list of supported serial devices.  I believe that the actual config
item CONFIG_USB_SERIAL_FTDI_SIO will appear in the help pop-up when you
have the right item selected.  Alternatively it shows up in the
bottom-right pane if you use make xconfig.  You can also safely just
edit this line in the .config file (remove the # and set it =y, and get
rid of the "is not set" verbage).

There is a manual.
http://www.gentoo.org/doc/en/usb-guide.xml
Gentoo Linux USB Guide, says:
"

this)

I just editted the config file. I've done that once before, and it worked
like a charm this time. I'm going to reboot in a minute and see if it works.
