Package: kernel-source-2.6.8 Version: 2.6.8-7 Severity: normal
A change form 2.6.7 to 2.6.8 in the error return handling of usb_stor_Bulk_max_lun() in usb-storage/transport.c exposed a problem with Minolta DIMAGE cameras, causing probing to fail, and thus these cameras cannot be used with 2.6.8. The included patch from the linux-usb-devel list claims to restore functionality.
