Also, i got an IOerror in your script, see attachement

In hostmode.py on line 144 witch is

dummy = os.popen('/root/vboost.sh &').read()

executing this

Code:

#!/bin/sh
echo "Stopping bme and raising power output to 5V"
stop bme; sleep 3; i2cset -y -m 0x07 2 0x6b 0x01 0x05; while true; do sleep 28; i2cset -y -m 0x80 2 0x6b 0x00 0x80; done

but reading back result gave error? MohammadAG?
I do not know python, but it seem that for some reason it can not reach the stage where you can mount your device.
can you reboot and click hostmode vbus,connect your USB and post the result from the fallowing commands in prompt:

Code:

ls /dev/sd*

Code:

ls /usr/local/sbin/i2*

and your full syslog, not only part of it.

WARNING
i2cset can be extremely dangerous if used improperly. It can confuse your I2C bus, cause data loss, or have more serious side effects. Writing to a serial EEPROM on a memory DIMM (chip addresses between 0x50 and 0x57) may DESTROY your memory, leaving your system unbootable! Be extremely careful using this program.

Do not play with it , as MohammadAG said you can regret if you do so.

Also if you can measure the output voltage form your USB post value here?
