The following reply was made to PR usb/101752; it has been noted by GNATS. From: Jim Segrave <jes@jes-2.demon.nl> To: bug-followup@FreeBSD.org, jes@jes-2.demon.nl Cc: Subject: Re: usb/101752: [panic] 6.1-RELEASE kernel panic on usb device insertion Date: Mon, 14 Aug 2006 15:28:55 +0200 I don't know if this is relevant, but in the Linux kernel (which does not panic with this device), I found the follwing comments in drivers/usb/storage/unusual_devs.h /* Casio QV 2x00/3x00/4000/8000 digital still cameras are not conformant * to the USB storage specification in two ways: * - They tell us they are using transport protocol CBI. In reality they * are using transport protocol CB. * - They don't like the INQUIRY command. So we must handle this command * of the SCSI layer ourselves. * - Some cameras with idProduct=0x1001 and bcdDevice=0x1000 have * bInterfaceProtocol=0x00 (US_PR_CBI) while others have 0x01 (US_PR_CB). * So don't remove the US_PR_CB override! * - Cameras with bcdDevice=0x9009 require the US_SC_8070 override. */ UNUSUAL_DEV( 0x07cf, 0x1001, 0x1000, 0x9999, "Casio", "QV DigitalCamera", US_SC_8070, US_PR_CB, NULL, US_FL_NEED_OVERRIDE | US_FL_FIX_INQUIRY ), -- Jim Segrave jes@jes-2.demon.nl
