For a long term solution, we'll need support from the kernel developers. = The fact that Sane uses the write/read interface to access SG devices=20 makes things indeed a bit difficult. Generally, the write and read=20 functions should not change the data in any way, but for the SG=20 interface, the situation is different. When the SG3 interface is used,=20 the SG driver needs to know, if the data was passed from a 32 bit or a=20 64 bit application in order to properly deal with the pointers passed as = the read / write data.
