Can't find Linux Input driver for using serial USB devices

[srekrap]

Hello  -

   Doesn anyone know where I can find the linux serial usb driver "input"? When I plug a USB serial device, TC doesn't create the /dev/ttyUSB0 node like I'm looking for... (I've looked in input-joystick, haven't looked in input-tablet yet...but would think there'd be an input-serial in this case...)

  Thanks

Hi srekrap
Maybe you are looking for  usbserial.ko  in  usb-serial-3.0.21-tinycore64.tcz?

Yes Rich - I found it - I'm done getting things working, and ready to start documenting what the heck I did - I would've been back to update this at some point -

    I was confused - I thought the input driver was doing the serial stuff - I didn't realize usb-serial was already installed (in addition to input) on my RHEL box - it was doing the work all along...

    Just curious... Perhaps you or someone else knows the answer -

       On RHEL /proc/bus/usb/devices shows USB serial things, but on TC there is no /proc/bus/usb/devices, I have to look in (as root) /proc/tty/driver/usbserial for a mapping of tty# and usb bus location... (we have strange requirements and multiple like serial devices to use simultaneously) - does anyone know why /proc/bus/usb/devices doesn't show up?

    Thanks

RH uses an old kernel. That was removed a while ago.

Could you paste output of

Code: [Select]

uname -a

mount|grep sys

@curaga -
 
  Oh - then that explains it... Thanks!

@tinypoodle -

  our RHEL is: 2.6.32-220.el6.x86_64, Nov 9 2011
  and of course tc is: 3.0.21, Feb 18 2012

I haven't observed such a path with much older kernels - and you didn't provide output from second command.

[curaga]

Even on older kernels one needs to mount it manually. On newer it's not possible anymore.

Ah yes, found that in the meantime myself, was "usbfs". I think most if not all of that info could nowadays be found under /sys.
