Hi,
I see that your CD-rom device is quirked to the wrong subclass (SCSI) in
usb2/storage/umass2.c:
#define UISUBCLASS_SFF8070I 5
#define UISUBCLASS_SCSI 6
bInterfaceSubClass = 0x0005
#define UIPROTO_MASS_BBB_OLD 2 /* Not in the spec anymore */
#define UIPROTO_MASS_BBB 80 /* 'P' for the Iomega Zip drive */
bInterfaceProtocol = 0x0050
Solution:
Try removing or limiting the following quirk:
{USB_VENDOR_MYSON, USB_PRODUCT_MYSON_HEDEN, RID_WILDCARD,
UMASS_PROTO_SCSI | UMASS_PROTO_BBB,
NO_INQUIRY | IGNORE_RESIDUE
},
--HPS
