Hi,
Note that currently the usb storage emulation is extremly broken anyway,
just writing to it produces I/O errors after a short while. This means
it can't be used very much at all.
When I tried last time, it did produce lots of kernel error messages in
the guest, but in the end the data was written correctly. So it doesn't
seem to be completely unusable.
I think it is actually the linux kernel being at fault here. I've seen
I/O errors on real hardware too, on my pretty old laptop which has usb
1.1 only. Probably something like timeouts being *way* too low for usb
1.1 xfer speeds.
cheers,
Gerd
