I'm a bit surprised that the SANE folks, who I took to be scanner-oriented, should be interested in graphic tablets. I know, from having used it in the days before I switched back to FreeBSD, that the verbose mode of the Linux usb lister gives all the info you could possibly ask for, I would really rather not use the Linux tool to do that, both for feelings of loyalty, and to be honest, my legs are too shot, and getting back and forth to my now moved Linux machine with the graphic pad is unfun. Maybe I will look at usbdevs and see if it's hackable to make it have a blabbermouth mode. Or, maybe the verbose mode of booting might be more verbose for USB devices? As far as the other side of things, to have a usb device that is identical to one on the list, except the mfr has moved the ident info, and have that driver be inaccessible to FreeBSD seems awfully straitlaced to me. Is it a feeling of the usb kernel developers involved that thjey should impose that level of control on folks? What, in the name of security, maybe? It seems that they might maybe protect it to some lenth, but to remove the abilityu to experiment easily, that sounds a bit too draconian. Is this really the sense of folks here, that no user-provoked experimentation should be allowed? -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHrgv6z62J6PPcoOkRAlKoAJ46/zBH/n0Mr2uaUnhF87IR1a8MsgCgm6Lz iaCPsQ1uPPcfGdl3/F+fJ4E= =QjY6 -----END PGP SIGNATURE-----
