LCDproc / Discussion / Help: Problems with LCDd 0.5.5 and BWCT USB Display (hd44780)

Hi,
When trying to use the BWCT USB device (http://www.bwct.de/lcd.html), LCDd won't start correctly, even when running it as root:

The section in LCDd.conf:

## Hitachi HD44780 driver ##
[hd44780]

# Select what type of connection. See documentation for types.
ConnectionType=bwctusb

# Port where the LPT is. Usual value are: 0x278, 0x378 and 0x3BC
#Port=0x378

# Device of the serial interface [default: /dev/lcd]
#Device=/dev/ttyS0

# Bitrate of the serial port (0 for interface default)
Speed=0

# If you have a keypad connected.
# You may also need to configure the keypad layout further on in this file.
Keypad=no

# Set the initial contrast (bwctusb and lcd2usb) [default: 500; legal: 0 - 1000]
Contrast=0

# Set brightness of the backlight (lcd2usb only) [default: 0; legal: 0 - 1000]
#Brightness=1000
#OffBrightness=0

# If you have a switchable backlight.
Backlight=no

# If you have the additional output port ("bargraph") and you want to
# be able to control it with the lcdproc OUTPUT command
OutputPort=no

# Specifies if the last line is pixel addressable (yes) or it controls an
# underline effect (no). [default: yes; legal: yes, no]
#Lastline=yes

# Specifies the size of the LCD.
# In case of multiple combined displays, this should be the total size.
Size=16x2

# For multiple combined displays: how many lines does each display have.
# Vspan=2,2 means both displays have 2 lines.
#vspan=2,2

# If you have an HD66712, a KS0073 or another 'almost HD44780-compatible',
# set this flag to get into extended mode (4-line linear).
ExtendedMode=yes

# In extended mode, on some controllers like the ST7036 (in 3 line mode)
# the next line in DDRAM won't start 0x20 higher. [default: 0x20]
#LineAddress=0x10

# Character map to to map ISO-8859-1 to the LCD's character set
# [default: hd44780_default; legal: hd44780_default, hd44780_euro, ea_ks0073,
# sed1278f_0b, hd44780_koi8_r, hd44780_cp1251, hd44780_8859_5, upd16314 ]
# (hd44780_koi8_r, hd44780_cp1251, hd44780_8859_5 and upd16314 are possible if
# compiled with additional charmaps)
CharMap=hd44780_default

# If your display is slow and cannot keep up with the flow of data from
# LCDd, garbage can appear on the LCDd. Set this delay factor to 2 or 4
# to increase the delays. Default: 1.
#DelayMult=2

# Some displays (e.g. vdr-wakeup) need a message from the driver to that it
# is still alive. When set to a value bigger then null the character in the
# upper left corner is updated every <KeepAliveDisplay> seconds. Default: 0.
KeepAliveDisplay=2

# If you experience occasional garbage on your display you can use this
# option as workaround. If set to a value bigger than null it forces a
# full screen refresh <RefreshDiplay> seconds. Default: 0.
#RefreshDisplay=5

# You can reduce the inserted delays by setting this to false.
# On fast PCs it is possible your LCD does not respond correctly.
# Default: true.
DelayBus=false

# If you have a keypad you can assign keystrings to the keys.
# See documentation for used terms and how to wire it.
# For example to give directly connected key 4 the string "Enter", use:
#   KeyDirect_4=Enter
# For matrix keys use the X and Y coordinates of the key:
#   KeyMatrix_1_3=Enter
KeyMatrix_4_1=Enter
KeyMatrix_4_2=Up
KeyMatrix_4_3=Down
KeyMatrix_4_4=Escape
SerialNumber=1297257800

Any ideas? A bug in Fedora 16 (https://bugzilla.redhat.com/show_bug.cgi?id=508047) looks like the same problem, but it was closed without fixing.

Thank you for your help,

Best regards,
Joerg
