USB HOST MODE! (Coming soon)
Through the efforts of many - this has been achieved - at least in basic form.
The n900 detected two USB devices - though did not have drivers for them. Egoshins post of earlier today. http://talk.maemo.org/showpost.php?p...&postcount=808 This is _not_ quite user-ready yet - but with the addition of http://talk.maemo.org/showpost.php?p...&postcount=803 - USB internal power - first got working by joerg http://talk.maemo.org/member.php?u=35572 it's almost there! In a week or two - we should be able to (with the appropriate cable) plug in (low powered) memory sticks or keyboards, and have it work. Or high powered stuff through USB hubs. This includes stuff that vastly expands the possibilities for the n900 - imagine a USB display adaptor showing a 'normal' desktop on any LCD. However - this requires a fair bit of software work. Getting to a state where this is user friendly requires work on understanding BME. BME is the battery managment entity. This controls many aspects of the phones power subsystem, and it looks like that to get powered hostmode at the moment, this needs to be killed/suspended. This means the phone won't charge when plugged in, and requires all sorts of hackery to pause BME. Workarounds for this would be great, but it's going to take some effort. To collaborate on this if you have kernel or reverse engineering skills: (we do not at this time need user perspectives, we know that plugging stuff into USB is cool.

Re: USB HOST MODE! (Coming soon)
in my opinion, nokia in the next update (maybe pr 2.0 ;) ), will introduce the USB OTG with same nokia USB OTG adapter that will include in the n8 package.

Because it did'nt met the USB Foundation requirements, it had to be disabled. |
Re: USB HOST MODE! (Coming soon)
maybe is marketing. If nokia activate the usb OTG, how many people acquire the cable?
I'm the first ;) |

if you like to catch up with what's been going on at the hostmode front during the last few weeks, I suggest you skip the whole bunch at start and read http://talk.maemo.org/showthread.php...950#post588950 and followups.

Re: USB HOST MODE! (Coming soon)
EXCELLENT WORK you guys just goes to prove what the N900 will be capable of EVENTUALLY !.
Problem left is the poor design of the usb port. |
Re: USB HOST MODE! (Coming soon)
I will reverse engineering of BME for food... ah my english, sorry ... for free :D
I want disassemble but i don't have assembler/disassembler for arm so point to one please. |
