fa157bdfe8
This patch (as1157) adds a no-name PS/2-to-USB keyboard+mouse adapter to the hid-dell driver. (The device shows up with a Product string saying "Generic USB K/B", nothing more.) This will force an initial "Set-LEDs" report to be sent to the device, without which it won't send any keystroke information. Several bug reports mentioning this device have been filed in various forums; the patch should resolve them. This is just a temporary stop-gap for 2.6.28. A later patch for 2.6.29 will introduce a more generic mechanism for "Set-LEDs", making this change (and the entire hid-dell driver) unnecessary.
