It would be better if we could handle this on kernel level somehow. Right now
we need these ugly workarounds for QtMoko, FSO and oFono. I am not happy at
all having code like in QSerialPort:
if(not read anything for 10s && port=/dev/ttyHSO_Applications)
IIRC the problem with USB reenumerating happens even when on 2G - but i am not
100% sure - i havent seen it for long time.
Maybe one well placed delay in kernel could solve this? Nikolaus reported that
if you enable debug/verbose for the hso driver, it's not happending. Maybe
crazy idea - replace all printk's with small delay and see what happens?
