You did not include enough information (there must have been a few more lines above the first you wrote down). But as Justin Gibbs already wrote in his reply, this is most probably caused by another device getting nervous because it can't complete its command, if the scanner does not disconnect and locks out other devices for up to a minute. (Well, it is in fact the driver becoming nervous, but that's an implementation detail :) You may be best off connecting your scanner to a second SCSI card. You know they are cheap ... Regards, STefan
