linux-toradex.git/drivers/usb/storage, branch v3.14 Linux kernel for Apalis and Colibri modules usb-storage: enable multi-LUN scanning when needed 2014-02-04T20:59:15+00:00 Alan Stern stern@rowland.harvard.edu 2014-01-30T15:43:22+00:00 823d12c95c666fa7ab7dad208d735f6bc6afabdc People sometimes create their own custom-configured kernels and forget to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug in a USB storage device (such as a card reader) with more than one LUN. Fortunately, we can tell fairly easily when a storage device claims to have more than one LUN. When that happens, this patch asks the SCSI layer to probe all the LUNs automatically, regardless of the config setting. The patch also updates the Kconfig help text for usb-storage, explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN.  This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.

Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN.  When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.

The patch also updates the Kconfig help text for usb-storage,

usb-storage: restrict bcdDevice range for Super Top in Cypress ATACB 2014-02-04T20:59:14+00:00 Alan Stern stern@rowland.harvard.edu 2014-01-30T15:20:29+00:00 a9c143c82608bee2a36410caa56d82cd86bdc7fa The Cypress ATACB unusual-devs entry for the Super Top SATA bridge causes problems. Although it was originally reported only for bcdDevice = 0x160, its range was much larger. This resulted in a bug report for bcdDevice 0x220, so the range was capped at 0x219. Now Milan reports errors with bcdDevice 0x150. Therefore this patch restricts the range to just 0x160.
