that is quite interesting, so the bandwidth is big enough to handle that over expresscard, no big amount of bandwidth is lost? How did you solve the drivers here? Were there any complexities by any chance, or did it work like normal? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
