Right. Even when/if ufi.c comes online, we'll have various oddballs like the 8070. > Your other questions I will leave to Pete... Answering in order, the right thing would depend on your objective. If you just want storage, you probably want ub disabled (unless you run a large SMP box where you flip KVM often; this is a typical scenario on IBM Bladecenter, which was one of big motivators for ub). If you like to monkey around with things, enable ub and send me bug reports, or better yet, patches. It should be semi-safe. Keep in mind that Linus is about to ship a broken ub as part of 2.6.9; you must run AKPM kernel if you enable ub presently. Performance should improve with time, but it may stay somewhat worse than usb-storage forever. I am interested in big anomalies though. One user reported a factor of 20 difference; that's seriously broken and must be fixed. To select at runtime is not coded, and I have no plan to do it. Sorry. It adds a complication which does not help a whole lot; it must be documented; once you I add it, I have to stay compatible with it. Which driver to run is not a decision an end user is supposed to make. I envision a distribution builder selecting one or the other, in which case a config option is preferred. A notable exception would be Gentoo, but that one is source compiled anyway... -- Pete ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
