Title:
  Timing problem (garbage characters) in lirc-driver for iMon PAD VFD
  15c2:0036

Status in linux-meta-lts-xenial package in Ubuntu:
  In Progress

Bug description:
  Binary package hint: lirc

  In the lirc-driver for the Soundgraph iMon PAD VFD, USB-ID 15c2:0036,
  there is a timing problem. Packets are sent too fast to the USB-
  Device. You can see that you are affected by this problem, if you find
  similar lines in your syslog:

  [...]
  Feb  6 08:06:09 mythtv kernel: [   47.727759] lirc_imon: vfd_write: send packet failed for packet #2
  Feb  6 08:06:09 mythtv kernel: [   47.978904] lirc_imon: send_packet: packet tx failed (-32)
  Feb  6 08:06:09 mythtv kernel: [   47.978909] lirc_imon: vfd_write: send packet failed for packet #4
  Feb  6 08:06:09 mythtv kernel: [   48.223802] lirc_imon: send_packet: packet tx failed (-32)
  Feb  6 08:06:09 mythtv kernel: [   48.223807] lirc_imon: vfd_write: send packet failed for packet #2
  Feb  6 08:06:09 mythtv kernel: [   48.471698] lirc_imon: send_packet: packet tx failed (-32)
  Feb  6 08:06:09 mythtv kernel: [   48.471703] lirc_imon: vfd_write: send packet failed for packet #1
  [...]

  To fix the problem, you can apply the enclosed patch and rebuild the dkms lirc modules:
  cd /usr/src/lirc-0.8.6/
  sudo dkms remove -m lirc -v 0.8.6 -k `uname -r`
  sudo patch -p0 < lirc-0.8.6-VFD_0x0036_timing.patch
  sudo dkms add -m lirc -v 0.8.6
  sudo dkms build -m lirc -v 0.8.6
  sudo dkms install --force -m lirc -v 0.8.6

  The patch will add some 20 microseconds delay before each package
  send. It's not the most beautiful solution, but until there is some
  corrected upstream, this will help.

  HTH, Edi
