The bug which was causing alternate bulk transfer packets to fail was due to misconfiguration of the receive bulk transfer endpoint. My own class driver masked the bug because of the particular order in which it configured the endpoints. The updated USB driver package should fix this problem for the serial port class driver. A couple of points to note: 1) When using the serial port class driver, the variable length bulk transfer option must be deselected. This option may benefit from another descriptive name in order to avoid confusion. 2) To avoid buffer overflow conditions on large transfers, all calls to the serial port receive functions should specify a buffer which is a multiple of the bulk transfer message size for the bulk transfer endpoint (usually 64 bytes). -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
