[Voyage-linux] Voyage and USB?

[Robert Haskins]

Personally, I think this is just a buggy USB driver. To add to the 
confusion, the 3v VIA PCI<==>USB adapter works just *fine* on my ubuntu 
system with kernel 2.6.8.1-3-386. And, the same adapter with usbserial 
adapters work fine on my FC3 system (for which I don't have the kernel 
version handy, but obviously, it is a recent kernel.)
