+USB 7-Segment Numeric Display
+Manufactured by Delcom Engineering
+
+Device Information
+------------------
+USB VENDOR_ID 0x0fc5
+USB PRODUCT_ID 0x1227
+Both the 6 character and 8 character displays have PRODUCT_ID,
+and according to Delcom Engineering no queryable information
+can be obtained from the device to tell them apart.
+
+Device Modes
+------------
+By default, the driver assumes the display is only 6 characters
+The mode for 6 characters is:
+ MSB 0x06; LSB 0x3f
+For the 8 character display:
+ MSB 0x08; LSB 0xff
+The device can accept "text" either in raw, hex, or ascii textmode.
+raw controls each segment manually,
+hex expects a value between 0-15 per character,
+ascii expects a value between '0'-'9' and 'A'-'F'.
+The default is ascii.
+
+Device Operation
+----------------
+1. Turn on the device:
+ echo 1 > /sys/bus/usb/.../powered
+2. Set the device's mode:
+ echo $mode_msb > /sys/bus/usb/.../mode_msb
+ echo $mode_lsb > /sys/bus/usb/.../mode_lsb
+3. Set the textmode:
+ echo $textmode > /sys/bus/usb/.../textmode
+4. set the text (for example):
+ echo "123ABC" > /sys/bus/usb/.../text (ascii)
+ echo "A1B2" > /sys/bus/usb/.../text (ascii)
+ echo -ne "\x01\x02\x03" > /sys/bus/usb/.../text (hex)
+5. Set the decimal places.
+ The device has either 6 or 8 decimal points.
+ to set the nth decimal place calculate 10 ** n
+ and echo it in to /sys/bus/usb/.../decimals
+ To set multiple decimals points sum up each power.
+ For example, to set the 0th and 3rd decimal place
+ echo 1001 > /sys/bus/usb/.../decimals
+
+
There also are a couple of utility routines drivers can use:
- usb_autopm_enable() sets pm_usage_cnt to 1 and then calls
- usb_autopm_set_interface(), which will attempt an autoresume.
-
- usb_autopm_disable() sets pm_usage_cnt to 0 and then calls
+ usb_autopm_enable() sets pm_usage_cnt to 0 and then calls
usb_autopm_set_interface(), which will attempt an autosuspend.
+ usb_autopm_disable() sets pm_usage_cnt to 1 and then calls
+ usb_autopm_set_interface(), which will attempt an autoresume.
+
The conventional usage pattern is that a driver calls
usb_autopm_get_interface() in its open routine and
usb_autopm_put_interface() in its close or release routine. But

+ * The vstusb module is a standard usb 'client' driver running on top of the
+ * standard usb host controller stack.
+ *
+ * In general, vstusb supports standard bulk usb pipes. It supports multiple
+ * devices and multiple pipes per device.
+ *
+ * The vstusb driver supports two interfaces:
+ * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg
+ * interface to any pipe with timeout support;
+ * 2 - standard read/write with ioctl config - offers standard read/write
+ * interface with ioctl configured pipes and timeouts.
+ *
+ * Both interfaces can be signal from other process and will abort its i/o
+ * operation.
+ *
+ * A timeout of 0 means NO timeout. The user can still terminate the read via
+ * signal.
+ *
+ * If using multiple threads with this driver, the user should ensure that
+ * any reads, writes, or ioctls are complete before closing the device.
+ * Changing read/write timeouts or pipes takes effect on next read/write.
