I'm also completely stuck at this point.

* N900 died after on-line upgrade attempt (yes, battery was full).
* Got flasher tool, fiasco image
* Put N900 on charger. Yellow light on. Eventually it switched off.
* Then started flasher-3.5 -F <name of image> -f -R
* Got message 'no suitable USB device found', as expected
* Plugged in N900. Yellow light on. Did not go into flashing mode.
* Same, but pressing 'u' on N900 kbd, then plugging in cable. No go.
* Also tried removing battery, plugging it in while connected. No go.

Basically the problem seems to be that the N900 won't go into flashing mode, whatever I do. I have checked 'dmesg' output on my laptop and there is no indication that it is even plugged in. The only time I see any activity is if I remove and re-install the N900 battery, then there's a very quick 'new high speed USB device..' followed by 'USB disconnect'.

I have used this same laptop to flash my N800 several times, without a problem. I also tried to flash the N900 from a desktop computer, to no effect.

Does anyone sit on any idea not already posted in some thread or mentioned on the wiki? I believe I've tried everything. At this point my N900 looks totally bricked, the only sign of life is that it appears to be able to charge. There isn't a flicker of life on the screen.
