Changeset 0d92638 in mainline for uspace/drv/usbkbd/kbddev.c

Timestamp:

Branches:

lfn, master, serial, ticket/834-toolchain-update, topic/msim-upgrade, topic/simplify-dev-export

Children:

Parents:

Message:

Added boot protocol static descriptor.

• The fallback does not work very well, because the usb_kbd_init() function receives the device even if it does not support boot protocol.

File:

• uspace/drv/usbkbd/kbddev.c (modified) (2 diffs)
