Re: Thread for problems getting USB hostmode working.
Hi I cant install h-e-n when I click to install I get a message:
Unable to install 'h-e-n (USB Hostmode GUI)' conflicting application packages. when I click on details I got: kernel-modules-maemo |

Here is dmesg output after a failed attempt and also a success with just the mouse: Code:

Re: Thread for problems getting USB hostmode working.
Woah! I switched to "full speed" instead of "low speed" with the hub and keyboard+mouse combo and now it works! Also, switching to "full speed" instead of "high speed" seems to have fixed my sd card reader (I had been sure it was USB 2.0... guess not)

I tried this with my powered hub earlier. Got my mouse/keyboard/sd reader all working ("full speed") and then ran boostoff. Instantly the devices stopped working. Ran the charge script, the devices still were not working. Am I doing something wrong? |
Re: Thread for problems getting USB hostmode working.
Yea, active hub SHOULD mean powered HUB - I use "should" because with so much designs and sometimes, pseudo-designs, You can never be sure. anyway, in 99% powered hubs, You will also get power on line connected to N900 - not so much possibility for manufacturers to limit that, would require very complicated circuit and probably conflict with device power-on-port discovery - so N900 should charge.
It's indeed strange that Your devices stop working when You try to use charger script. Maybe Your power supply can't provide enough current to power both keyboard/mouse and N900? Its strange a little, because mouse and keyboard don't need much power. |

hi techs...first of let me thank all d developers and ppl on this thread who r helping us to make h-e-n working on our charming n900...
jus becoz of this thread i was able to make use of such a grt feature hidden in n900...thanks ppl :):) now i ve also got some issues wid h-e-n on my device... it reads my keyboard,mouse and my 4gb pendrive but it fails to read my 1 TB.:mad:i cant figure it out.though the light gets light up when connect to n900 but it says unable to connect no file system found....plz plz help me make it work...my hard drive(1tb) is working perfectly in my lappy... ps. my hard drive does not require an external power.. |

Thats the case, why many power-hungry peripherals that work fine on desktop/laptop need powered hub or Y-cable on N900. also, You may want to read cheve feedback few posts before - he succeed getting his HD to work by just slowing down mounting process (that's probably unrelated, but worth try) --- Side note - and thats only my personal opinion - if You consider using less "luser like" shortcuts in Your posts, it would be much easy to read them. |

Some hubs (obviously the one in post above that estel answered is one of them) even *sense* if there's power from upstream and accordingly power up the downstream ports, even though external power to hub is applied. Generally speaking you'll need the Y-cable between N900 and hub, not usually though between hub and peripheral. There's a very simple test if *your* hub supplies power to upstream port: power the hub, connect *switched off* N900 to upstream port with adapter. If N900 shows any reaction (startup, LED flashing etc) then the hub delivers power to N900. Otherwise not. cheers jOERG |
Re: Thread for problems getting USB hostmode working.
Again no need to sorry - it's very useful info, that you provided. I'm sorry that i provided wrong info -strange thing, that all USB 2.0 HUBS i used doesn't separate power from upstream port, i was really sure that it's common habit.
If they tend to separate it, they do it with some rationale, do they? What is the danger of using non-separating USB hub? I encountered only one strange - amusing, but not dangerous - thing when using such a hub. It was powered by ATX power supply, that i use also to power my other things around computer, like WC (water cooling, not toilet) fan controller - using 5V to operate and 12V to power up ventilators. One time, my ATX was turned off, while HUB still connected to it and to my notebook. What was my surprise, when on notebook power-on, Fan controller also waked up - fans we're not turning, but controller itself worked. It turned out that power from my notebook flow by the upstream port of HUB and its power plug to the (powered down) ATX power supply, then, by its lines, to fan controller. I just wonder if this single-diode design can also separate-to-powerplug power, not only powerplug-to-separate - will check that. |

i m preety sure it does not require external power source.i ve also tried cheve method of slow mounting but it didnt solve my problem. what do i do now? plz go through my attachment. do i need to use a usb hub/y connector and a usb charger to supply d deficient charge?? |
