can you dump to USB devices?

Hi!

While debugging the tstile machine I tried to use a USB flash disk as
swap/dump device.

When I tried kernel core dumping to it, I see

db{0}> reboot 104

dumping to dev 168,1 (offset=8, size=33524131)
dump i/o error


There is just a short pause between "dump" and "i/o error".

Is this supposed to work or not?
