I would like to use the IR transmitter included in a cubox. I did not found any documentation to use it, so I would want to learn how to communicate with periphericals on linux. Commands like lshw,lspci did not gave me any information, I think I would have to make it recognizable by the kernel in adding a module, but firstly, my guess is that there is somewhere a way to identify the periphiphical.Here is the outpout of the command dmesg | grep tty[    0.000000] Kernel command line: root=/dev/mmcblk0p1 rootwait rw console=tty1 console=ttymxc0,115200 consoleblank=0 video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24,bpp=16 dmfc=3 ahci_imx.hotplug=1 pci=nomsi loop.max_part=15[    0.000952] console [tty1] enabled[    0.486266] 2020000.serial: ttymxc0 at MMIO 0x2020000 (irq = 58, base_baud = 5000000) is a IMX[    1.427117] console [ttymxc0] enabled[    1.431600] 21f0000.serial: ttymxc3 at MMIO 0x21f0000 (irq = 61, base_baud = 5000000) is a IMXttymxc0 and ttymxc3 could be the ir receiver and transmitter, but how to be sure, and how communicate with such devices?  I already been able to receive IR signals from the IR receiver with the lirc command irrecord, but the irsend command returns the error hardware does not support sending
