Re: [coLinux-users] Is USB supported?

[Sean C. <sea...@co...>]

Ok,

I added the path.  I tried a few different variations from the 
dmdiag.exe output.  No joy.  Which of the various ways of referring to 
the USB Stick should I be using?   BTW, it looks to me like the stick 
has 2 paritions on it.  Very odd.
