Linux driver help in usb_dev_bulk example

Sachin Grover
Prodigy 220 points

I loaded the bulk example in my ek-TMC123GXL device and modified the vendor id  and product id in usb_skeleton.c

On loading the driver on Linux, I am getting my device file in /dev and when I am issuing the write command to the device file in /dev my board respond with the led blink as specified in the firmware code but on reading I am not getting anything and even the terminal stuck at that point. Help me to solve the issue.

I tried writing and reading through echo/cat as well as through a user space application.
