       bcharge - program to set BlackBerry handhelds to 500mA




       bcharge  is a program that sends a special handshake to all BlackBerry devices it finds on
       the USB bus.  This handshake causes the device to reset itself,  and  then  request  500mA
       instead of the usual 100mA.  This allows proper charging on Linux.

       It  is  safe  to  run this command multiple times, as it only changes devices that are not
       already set to 500mA, or are not in the desired mode.


       -o     For Blackberry Pearl devices, using this switch causes bcharge to set  the  Product
              ID to 0001.

              When  the Pearl is in 0004 mode, two USB interfaces are presented: one for database
              access and one for mass storage.   In  0001  mode,  only  the  database  access  is

              Before  bcharge  is  run,  the Pearl shows up with a Product ID of 0006, which only
              gives mass storage functionality.  You must run bcharge for the Pearl before  using

       -d     This  switch  is for the Blackberry Pearl to switch it back to 0004 dual mode after
              having run bcharge with the -o option.  Alternately, newer devices (such  as  Storm
              with  product  ID of 8007) will be switched to 0004.  Since a Pearl in mode 0001 is
              practically indistinguishable from a classic Blackberry, the -d switch is needed to
              tell bcharge that you really are working with a Pearl.

       -g     Guess  whether Dual mode is needed.  If USB Interface Class 255 is not found on the
              device (the class used for database access), then dual mode is set.  Otherwise, the
              device is left as is.

       -h     Help summary.

       -p devpath
              If  your  system runs a kernel with CONFIG_USB_SUSPEND enabled (some Ubuntu kernels
              have this turned on, as well as some Fedora 7  kernels),  then  you  also  need  to
              adjust  the  suspend  state  to avoid going into power saving mode.  This option is
              used when run from udev, using a rule such as:

              BUS=="usb",   SUBSYSTEM=="usb_device",   ACTION=="add",    SYSFS{idVendor}=="0fca",
              SYSFS{idProduct}=="0001",     SYMLINK+="bb-%k",    GROUP="plugdev",    MODE="0660",
              RUN="/usr/sbin/bcharge -p %p"

              When using this option, you will almost always need to be root.

       -s path
              Specify the mount point for the sysfs filesystem.  On most systems this is  mounted
              at /sys which is the default.
