Re: [Announce] USB hostmode beta release
I've been trying the charger.sh script, however whenever I execute it, the mounted media is unmounted, and cannot be accessed unless I close h-e-n/xterm and start again.
Steps:
After charger.sh is executed, the media is unmounted. Any ideas? |

When charger.sh runs and no charger is providing power - where is power from then? -> hostmode terminated /j |

Ahh - I misinterpreted when to plug in the ac adaptor. Cheers joerg_rw.
Edit: just confirming that this now works.

Re: [Announce] USB hostmode beta release
Not mean to be "picky", but boostoff (before executing charge.sh) would be also useful ;) Sure, it (probably) also works without doing so, but there is no point in keeping it, if You want power-saving, or charging as quickly as possible.

Re: [Announce] USB hostmode beta release
Managed to mount a 500Gb passport HDD today, that formerly wouldn't mount (insufficient power from the N900). Rather than use a powered hub to power the drive, and then a separate AC adaptor to charge my N900, I modified the AC adaptor to have three USB ports: original port, that will charge my N900 over the Y cable, and a pair of ports that act like a female-female adaptor for joining two male ends together. These pair of ports take +ve/-ve from the AC adaptor, so in one port you plug your media/peripheral to be powered, and the other port takes the data cable that goes to your N900 (the other part of the Y cable). See picture. Probably not the safest thing going, but I will be tidying it up.

@ hostmode script ( worklog )
until now ...
status area icon - ok . it is a stock icon, blue. it is activated when an valid device is connected. tap on status area will show an text saying "Host mode active". More informations and actions will be added later after the moment when the script is stable switching ( guessing ) speed work almost well. it is based on dmesg output there is multiple ways doing this but not all are reliable. after 300 tests... first method first starting as high speed then low then full. reason : most connected devices are usb sticks, on second place mouses or keyboards for this method there is a problem for sensing low speed devices in high speed mode. khubd daemon interfere with driver and is hard to put whole system in a stable state. second method started as full speed and watching dmesg messages switch the speed accordingly. the fastest method, only 2 steps reason : if an full speed device is connected it will work "instantly". high speed devices are detected also in full speed mode and dmesg output is useful but there is a problem with low speed device in full speed mode and khubd go crazy. this will add 20 s for a stable state. more tests are needed in this mode third method start as low speed then full then high. the most stable method reason: low speed devices are detected "instantly" high or full speed devices are detected well. so continuing as full speed, the "full"devices will work and "high" devices are properly signalized khubd and g_file_storage make a lot of problems. for khubd there is an workaround flushing all configs but add 20 s for each khubd error. g_file_storage need a patch because in high speed mode when a low speed device is attached it will trigger "mass storage" "Pc suite" selection. this can be ignored but is annoying. a preference can be set in the script for first tested speed later or tomorrow an alpha variant will be posted |

@blue_led:
why is problem with autodetection usb speed? and it is possible to check if host usb device or charger is connected? |
