Critical and others problems with hostmode

Device - N900
OS - Maemo 5
V. 21.2011.38-1 (CSSU)
kernel-power 1:2.6.28-10power50
hostmode-gui 0.3

With that "hostmode-gui" (h-e-n) I can easily initialize USB-device but
it don't want to mount on my FS with that gui. So, I need to mount it
(and umount) mannualy.
Today I found a critical problem with using h-e-n. I did not use it from
the last summer and I don't remember what of version of "kernel-power" I
used that time (of course. not v.50 as now :) ) and whether I used CSSU
or not but I had no that problem at that time. (But at that time it
needs for me to start bme mannualy after closing h-e-n windows becouse
it didn't start automatically and at one time I even had problems with
(re)booting my device).
Now, since today, when I close the "h-e-n" gui, my device suddenly is
shutting down and I need to boot it for working with it.
How can I resolve the above-mentioned issues?

Hi,

shutdown after closing h-e-n GUI can be caused by starting BME
when bq27x00_battery driver is loaded. BME and bq27x00_battery
cannot be loaded at same time. So make sure that bq27x00_battery
is blacklisted in /etc/modprobe.d/* and also is NOT in list
/etc/modules

automounting FS in usb hostmode (without pressing mount button or
mounting via terminal) will work if you update kernel-power to
v50 and ke-recv to last version. Last version of ke-recv will be
updated with next CSSU update. So wait for next CSSU and
automouting will work.

Thanks. Yes, I have the bq27x00_battery driver is loaded:
lsmod | grep bq27x00_battery
bq27x00_battery 6480 0
power_supply 6916 1 bq27x00_battery

I enabled it for purposes getting temperature as it discribed in the
page "http://wiki.maemo.org/Overclocking"
So, if I want use h-e-n I need to disable it?

Thanks for your answer.
But I was not strictly correct, I cannot mount it not only automatically
but also using mount-button in h-e-x. I can mount only via terminal
command.

Yeah, thanks, there was that problem. After rmmoding bq27x00_battery it
works without the problem of device's OS shutting down.

You cannot run BME and bq27x00_battery together. So you can load
bq driver when BME is stopped and before starting BME driver must
be unloaded.

So normal usage is: stop BME, load bq driver.... then remove bq
driver and start BME.

h-e-n gui is stopping BME, so when h-e-n is open you can load bq
driver, but do not forget to unload it before closing h-e-n.

If you can mount it via terminal, automounting with new version
of ke-recv will work. Wait for next CSSU. If it will not work
with next CSSU + kp50 write me then.
