Thread: KB&M not working after Altera Quartus USB Blaster rules.d changes

yesterday got altera quartus ii web edition 12.1 software working on laptop installed play de1 board. i'm running ubuntu 12.04 based distro (mint nadia 14 64bit). usb blaster work had follow example here (steps 5 , 6) , worked , program , write fpga heart's delight... until booted morning , found keyboard , mouse (trackpad actually) not work @ login screen anymore. tried solution posted here see if problem unrelated usb blaster rule changes no luck.


mentioned followed steps 5 , 6:


created file @ /etc/udev/rules.d/ , called 51-usbblaster.rules

code:

# altera usb-blaster rule set mode 666. subsystem=="usb", env{devtype}=="usb_device", attrs{idvendor}=="09fb", attrs{idproduct}=="6001", mode="0666", name="bus/usb/$env{busnum}/$env{devnum}", run+="/bin/chmod 0666 %c"

code:

sudo udevadm control --reload-rules

note made changes suggested in comments: attrs instead of attr


that's significant change made yesterday that's culprit.


mouse , keyboard don't work, suspect fixing going little difficult. tried plugging in external usb mouse , keyboard didn't work either.
ideas now? how can revert changes or change rules still work usb blaster not conflict m&kb?
thanks!

solution:


turns out code on step 5 of tutorial has on single line in 51-usbblaster.rules file. web formatting makes appear multiple lines, must correct when create file.


now, if me you've made mistake undo must:


1. boot recovery mode. hold shift key after bios splash grub menu if youre running single boot system , don't see grub menu
2. once log in root filesystem mounted read only. must mount read/write if want fix rules file, enter command

code:

mount -o remount,rw /

3. edit rules file

code:

sudo nano /etc/udev/rules.d/51-usbblaster.rules

, move code onto 1 line (the comment can stay on own line, obv)
4. save , exit (ctrl-x, y)
5. reboot

code:

reboot

, should it!


system working fine , quartus ii software; can write de1 no problem.
