Running ts_calibrate for touchscreen on emmbedded Linux enviorment
Hey guys, I am trying to figure out why this touchscreen is not working. I am attempting to run ts_calibrate which (on my kernel) can be found @ usr/bin When I run the script:
I am assuming I need to provide an argument so I am trying to figure out what the ts would be called. I check out /dev/input:
It's not showing up here unless its event0 or event1 any idea what the problem might be. The ts is plugged in via a usb cable. Is there somewhere in the kernel I can probe to find out if the board is recognizing the ts?
EDIT: I tried:
EDIT: So a little detail. I had a working ts and it broke (still works but screen is cracked) oredered a replacement. Plug that replacement in and it while it does show the application you can't interact with it. An lsusb with the old device plugged it shows three usb devices:
and if you look above you will see that an lsusb with the new device only shows two. Perhaps this is a usb issue? Is there a usb configuration script I need to run perhaps?
I use /bin/ksh

lsusb
lsusb(8) Linux USB Utilities lsusb(8)NAME
lsusb - list USB devices
SYNOPSIS
lsusb [ options ]
DESCRIPTION
lsusb is a utility for displaying information about USB buses in the system and the devices connected to them.
OPTIONS -v, --verbose
Tells lsusb to be verbose and display detailed information about the devices shown. This includes configuration descriptors for the
device's current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communi-
cations, and chipcard.
-s [[bus]:][devnum]
Show only devices in specified bus and/or devnum. Both ID's are given in decimal and may be omitted.
-d [vendor]:[product]
Show only devices with the specified vendor and product ID. Both ID's are given in hexadecimal.
-D device
Do not scan the /dev/bus/usb directory, instead display only information about the device whose device file is given. The device
file should be something like /dev/bus/usb/001/001. This option displays detailed information like the v option; you must be root
to do this.
-t Tells lsusb to dump the physical USB device hierarchy as a tree. This overrides the v option.
-V, --version
Print version information on standard output, then exit successfully.
RETURN VALUE
If the specified device is not found, a non-zero exit code is returned.
FILES
