No. But I checked dmesg. usually nothing in there.
But one single time after reboot, I got the "mass storage or PC mode?" requester when enabling VBUS. Probably caused by >>VBUS detected; bme due to race not yet noticed boostmode; no short D+/- so no charger -> this has to be a host PC plugged in to N900<< (I simply did the i2cset without suspending bme)
Funny part 1: VBUS stayed on for several minutes, until I finally hit 'PC mode' on requester.
Funny part2: this is the resulting dmesg:
