Hi,
I am using Ubuntu 9.10 (Karmic Koala) for accessing openpcd v04 reader. I have successfully downloaded main_dumbreader firmware to AT91SAM7 chip. I can toggle red LED as well. When I tried accessing CLRC632 registers using /opcd_test -r I am not able to. Then I tried reading tags using ./librfid-tool -s but receive a message "No openpcd found...............No Cardman 5121 found"
After debugging I realized that it is not able to open the reader handle and also on giving dmesg | grep ttyUSB does not display any message or "connected disconnected messages". I did not have modprobe.conf files in modprobe.d , I did create one and added "options USBserial product and vendor " as written in the firmware page. But, still no success.
Now, I have realized that I am getting "error opening reader handle...No openpcd found" because the reader module is not getting loaded successfully. There is USB issue. Though I have added 62-openpcd.rules to /etc/udev/rules.d and also librfid.rules to /etc/udev folder.
My librfid.rules files added is as follows:
# This file is part of the librfid distribution
#
# udev rules file for supported readers
#
#
ACTION!="add", GOTO="librfid_rules_end"
SUBSYSTEM!="usb_device", GOTO="librfid_rules_end"
# Omnikey 5121
SYSFS{idVendor}=="076b", SYSFS{idProduct}=="5121", MODE="0664", GROUP="users"
# Openpcd
SYSFS{idVendor}=="16c0", SYSFS{idProduct}=="076b", MODE="0664", GROUP="users"
LABEL="librfid_rules_end"
Can anyone please tell still why it is not able to load reader module? Or is it because of Ubuntu 9.10.
Do I need to add some more rule file or make some changes to existing file.
Thanks & regards
Kirti
