From 4b6aa59999a3a12dd4740a52299c6c33e85a8747 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Villac=C3=ADs=20Lasso?= Date: Tue, 28 Aug 2007 15:58:31 -0700 Subject: [IrDA]: Kingsun KS-959 IrDA USB driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This dongle does not follow the usb-irda specification, so it needs its own special driver. First, it uses control URBs for data transfer, instead of bulk or interrupt transfers; the only interrupt endpoint exposed seems to be a dummy to prevent the interface from being rejected. Second, it uses obfuscation and padding at the USB traffic level, for no apparent reason other than to make reverse engineering harder (full details on obfuscation in comments at beginning of source). Although it is advertised as a "4 Mbps FIR dongle", it apparently loses packets at speeds greater than 57600 bps. On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4959 . The Windows driver that is used normally to control this dongle has a filename of KS-959.SYS . Signed-off-by: Alex Villacís Lasso Signed-off-by: Samuel Ortiz Signed-off-by: David S.
