I have to admit this is a bit above my head. How do I know how many=20 urbs are sent / received if I do a bulk transfer? It seems you're=20 using an estimate in mustek_usb, but how do you know how many bytes=20 you're transferring in one urb? Even if I find out this number for my=20 scanner model, how would I know if it is correct for all other=20 scanner modules the backend supports? I must say I quite dislike the whole idea of making an estimate on the=20 number of urbs in the backend. Shouldn't this be handled in libusb=20 directly?=20 =2D -Oliver =2D----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQFAR7xI/V6sbrmfIuMRAg5GAJ9ky6jFbZB+zSNAfIcRZeiZHF4MmACfS9WL 2JW+s6/V/olouLUDEBm0PGE=3D =3DzCYL =2D----END PGP SIGNATURE-----
