The uSCSI from Newer Technology is a SCSI-USB converter with USB ID 06ca:2003. Like several other SCSI-USB products, it's a Shuttle Technology OEM device. Without a suitable entry in unusual-devs.h, the converter can only access the (single) device with SCSI ID 0. Copying the entry for device 04e6:0002 allows it to work with devices with other SCSI IDs too. There are currently six entries for Shuttle-developed SCSI-USB devices in unusual-devs.h (grep for euscsi): 04e6:0002 Shuttle eUSCSI Bridge USB_SC_DEVICE, USB_PR_DEVICE 04e6:000b Shuttle eUSCSI Bridge USB_SC_SCSI, USB_PR_BULK 04e6:000c Shuttle eUSCSI Bridge USB_SC_SCSI, USB_PR_BULK 050d:0115 Belkin USB SCSI Adaptor USB_SC_SCSI, USB_PR_BULK 07af:0004 Microtech USB-SCSI-DB25 USB_SC_DEVICE, USB_PR_DEVICE 07af:0005 Microtech USB-SCSI-HD50 USB_SC_DEVICE, USB_PR_DEVICE lsusb -v output for the uSCSI lists bInterfaceSubClass 6 SCSI bInterfaceProtocol 80 Bulk (Zip) This patch adds an entry for the uSCSI to unusual_devs.h.

Linux Braille Console
To get early boot messages on a braille device (before userspace screen
readers can start), you first need to compile the support for the usual serial
console (see serial-console.txt), and for braille device (in Device Drivers -
Accessibility).
Then you need to specify a console=brl, option on the kernel command line, the
format is:
console=brl,serial_options...
where serial_options... are the same as described in serial-console.txt
So for instance you can use console=brl,ttyS0 if the braille device is connected
to the first serial port, and console=brl,ttyS0,115200 to override the baud rate
to 115200, etc.
By default, the braille device will just show the last kernel message (console
mode). To review previous messages, press the Insert key to switch to the VT
review mode. In review mode, the arrow keys permit to browse in the VT content,
page up/down keys go at the top/bottom of the screen, and the home key goes back
to the cursor, hence providing very basic screen reviewing facility.
Sound feedback can be obtained by adding the braille_console.sound=1 kernel
parameter.
For simplicity, only one braille console can be enabled, other uses of
console=brl,... will be discarded. Also note that it does not interfere with
the console selection mechanism described in serial-console.txt
For now, only the VisioBraille device is supported.
