Hi Alan, The tty low_latency variable is set to 1 in hso_serial_open in linux, Maybe you were removing duplicate setting of this variable but if it was your intention to set it to 0 it's not being done. Also the 2.6.29-rc1 driver hangs the kernel on linux-2.6.28-rc6 when a device is connected, I've still got to test it on 2.6.29-rc1. -- best regards, D.J.
