Hi Pierre, > It is one of the gl84x. The gl841 and gl842 are identical, but the gl843 > has small differences. There are writes on some register bits not > defined for gl841/2, but i don't know if those are relevant.
Hm. The scanner has 2400x4800 dpi, but the data sheet for the GL841 says: "Available sensor types: 600, 1200, 2400 dpi color CIS or CCD." The GL843-3x-data-sheet says: "Available sensor types: 600, 1200, 2400, 3200, 3600, 4800dpi color CIS or CCD." (See http://www.genesyslogic.com/jimages_product/GL843-3X%20Datasheet_102.pdf) May be, you are right. I know, it is'nt really necessary, but I made another scan with XP. (Here works a trainee for two weeks - he should learn such things.) The size is only 42.5 MB, after processing 33 MB. We've got at startup nearly the same data: diff usbsnoop-w98-cal.collect.log usbsnoop-xp-cal.collect.log starts with: 1c1 < set_read_register(0x41) = 0x50 --- > set_read_register(0x41) = 0x58 3c3 < set_read_register(0x41) = 0x50 --- > set_read_register(0x41) = 0x58 32873c32873 < BULK<(65024) --- > BULK<(65536) 40790d40789 < BULK<(65024) 41066a41066 > BULK<(65536) 48919d48918 < BULK<(65024) 49259a49259 > BULK<(65536) 57048d57047 ... The first changes belonging to registers are: 122891,123345d123101 < 0xaa, 0xaa,set_register(0x5b) < write_register(0x00) < set_write_register(0x5c, 0x00) < set_register(0x28) < buf_prepaccess(0x00000600,BULK_OUT) < Data: 01 00 82 00 00 06 00 00 < Index: 0 < BULK>(1536) < 0x55, 0x55, 0x55, 0x55, 0x55, 0x55, 0x55, 0x55, So I think, we have really the right data ...
