LinuxQuestions.org - ttyUSB0 not found

Hello,

I have an easymouse 2 USB-serial card reader. It worked perfectly with Openelec 4x. Since the update to Openelec 5x I can't access the easymouse. I see under dev the /ttyUSB0 device but can access it.
When I plug the usb reader off and on I can't see the usb device with dmesg | grep tty.

When I'm using lsusb I can see the device:

Code:

Bus 003 Device 007: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

When is use the command: usb-devices
I see the following:

Code:

T:  Bus=03 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#=  7 Spd=12  MxCh= 0

D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1

P:  Vendor=0403 ProdID=6001 Rev=06.00

S:  Manufacturer=FTDI

S:  Product=FT232R USB UART

S:  SerialNumber=A7031G76

C:  #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=90mA

I:  If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)

So there is now driver.

modprobe ftdi_sio.ko gives me

Code:

modprobe: FATAL: Module ftdi_sio.ko not found.

I think I need the ftdi-sio.ko driver. How can I install or activate it?
