Hi
I am using arm-linux-2.6.13. Processor is PXA 255.
I have enabled USB Gadget Support in the kernel.
I am inserting following modules for USB communication.
g_serial.ko and pxa2xx_udc.ko.
While inserting g_serial.ko i have given this option (use_acm=1 ) since
this is required for Windoows Host.
Now when i connect my board with PC using USB cable ,PC detects my
device as Gadget Serial .
I open HyperTerminal on this newly detected Gadget Serial Port.
Setting of Hyper Terminal for this port are Gadget Serial are 115200, 7
bit data , 1 parity and No hand shaking.
My problem is
When i send data greater than 64 bytes from client(my board PXA255) to
host ( PC ) , i get only first 64 bytes.
( 64 bytes is the max packet size of usb bulk end point)
I can send data of 1k lenght if i devide 1k data in chunks of 64 byes.
But a write call with no of bytes greater 64 bytes always fails.
I have disabled hand shaking (~RTSCTS) on usb port.
Does anybody has faced this problem.
Your advice will of great help.
Best Regards
Anup
