The only thing i can agree upon is that it would not make much sense to *pay* someone to develop a driver for such low end hardware. But other than that: * as a user, having a wider choice is always a good thing not to mention that many times such cheap cards are available more or less for free. * from the FreeBSD point of view, having more cards supported means more "satisfied users" and thus it is better for the project. and finally, as a developer (as opposed as a simple user) i am a bit uncomfortable in talking about economical issues... just consider the time and money i (as many many others) have invested in the project both for developing stuff and supporting it... > > for driving a low throughput device e.g. a scanner i'd rather not have > > to use a 2940 as i am doing now... > > Why? Plenty of leftover bandwidth for other devices. scanners tend not to release the bus between request and response, so you will not be safe in putting other peripherals (e.g. disks, CD writers, etc) on the same bus unless you can tolerate other I/O to get stuck while the scan proceeds. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
