PL2303 Driver issue with provided Kernel

Hey Folks,


iam using the zedboard with the newest release of analog devices (Linaro 14.04. Kernel: 3.17.0-g18efa1b) while i was trying to mount a GPS-Mouse to the USB-Port i recognized that there are some issues with the PL2303 usb serial driver.


1) When enter "lsusb" in the promt:

Bus 001 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


2) dmesg | grep USB

ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver

Found TI TUSB1210 ULPI transceiver.

zynq-ehci zynq-ehci.0: Xilinx Zynq USB EHCI Host Controller

zynq-ehci zynq-ehci.0: new USB bus registered, assigned bus number 1

zynq-ehci zynq-ehci.0: USB 2.0 started, EHCI 1.00

hub 1-0:1.0: USB hub found

usbserial: USB Serial support registered for generic

usbserial: USB Serial support registered for FTDI USB Serial Device

usbhid: USB HID core driver

usb 1-1: new full-speed USB device number 2 using zynq-ehci


So the PL2303 device will not be attached to any tty.


3)  modprobe usbserial vendor=0x067b product=0x2303

modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file '/lib/modules/3.17.0-g18efa1b/modules.dep.bin'


there is no module for the 3.17.0 kernel..


4) ls /boot  grub

abi-3.13.0-24-generic         initrd.img-3.13.0-24-generic

config-3.13.0-24-generic      vmlinuz-3.13.0-24-generic



It shows the 3.13. kernel but not the 3.17.0.. why is the kerne version 3.17.0 (uname -r), and i cannot found anything about it in the system?


I hope you can help me


kindly regards
