Hi folks,
Well, this took way too long to figure out. :-)
If you are running a kernel with CONFIG_USB_SUSPEND enabled, then
your system will have a /sys/bus/usb/devices/usb.../.../power
directory that contains two files: state and wakeup.
On these systems, it seems that even after bcharge is run, the kernel
suspends the Blackberry. You can determine this by cat'ing the
power/state file. If it says 2, it is suspended, and the charge
icon is likely off.
You can resume normal operation by doing:
echo -n 0 > /sys/bus/usb/devices/usb..../power/state
The proper path for your device will show up in the 'dmesg' output, like
this:
usb 3-2: new full speed USB device using uhci_hcd and address 5
PM: Adding info for usb:3-2:1.0
In this case, the command would be:
echo -n 0 > /sys/bus/usb/devices/usb3/3-2/power/state
The -n is important, since echo adds a newline to its output, and the
kernel will balk at that.
Now to find a user-friendly way to do this automatically... :-)
