Hi,
Regarding the patch I posted to prevent the bus scan of SCM USB-SCSI
converters attempting to scan the converter itself, there is probably a
neater way.
In drivers/scsi/scsi_scan.c, function __scsi_scan_target(), there is:
if (shost->this_id == id)
/*
* Don't scan the host adapter
*/
return;
Since __scsi_scan_target() takes care to avoid scanning the host adapter, we
just need to set this_id to 7. Untested patch below.
