For that reason , please , start from FreeBSD : Select drivers of possible devices to use , such as SANE , CUPS . Then review their documentation . Find a device which can work with these packages . Select such a trade mark that it will be "famous" means its user base is large , and ignore trade marks "no-one heard" it . In that way , if you ask a question about it , it will be likely that you will find user(s) using your selected device . It may not work in FreeBSD , due to ( not set correctly or suitable ) parameters ( either one will supply to you information about them or you can generate a bug report , it will be likely there will be person(s) trying to help ( able to help ) because you have selected an open source driver using that device . Over time , knowledge will accumulate to solve such problems . Another information source is FreeBSD release documentation : In them , there are information which devices are supported . Some of them may be old , but , even some of them can be found , especially in www.amazon.com or other large suppliers of computing hardware . For that try to buy single purpose devices : printer , scanner , etc. , not in combination . Do NOT start from reverse : Buy hardware whatever it is , then try to use it in the FreeBSD , even in Linux . It is very likely that you will fail to find a suitable driver ( if you can not write such a one ) .
