Question

Hello , I am newbie to MAC. I am writing a Device Firmware Updater for a Bluetooth Headset device on Mac OS X 10.5.7. while downloading the firmware I keep on getting "Transaction Timeout" errors very frequently. The application runs successfully for firmwares having size less than 700KB but it gives error "Transaction Timeout" for firmware having size 1.2MB.

I am writing firmawre on device in block of 1023bytes. My program is writing some blocks and after sometime it halts giving error "Transaction Timeout"

I am using funtion DeviceRequestTO() for the purpose of writing firmware on device.

Please, can anyone help me.....?
