I disabled ehci in my kernel, so NetBSD uses ohci driver now - and now
I am able to write to USB mass media without problems (well, so far ;)
while when using ehci every attempt to write to USB memory sticks and
CF cards (in a CF card reader) failed (the tar / cp / whatever process
got stuck and no data was written to the mass media).

dmesg says:
