Update: I now successfully connected a flash drive, only my keyboard prob prevails. Done the same steps, but connected hw cable to n900 after vbus boost, and thus before enumerate (rather then connecting all before any operation). Now I can use the flashdrive on my N900

But the keyboard is still the same, no led activity or any other. Have tried connecting hw cable between step vbus and step enumerate, but no success. At least I now know HW mode sorta works on my N900, so this is probably my fault rather than hw/software? Fingers crossed.

Ty in advance
