CC-DEBUGGER: Report for USB560 v2 System Trace (BH-USB-560v2) booting error

Part Number: CC-DEBUGGER
Other Parts Discussed in Thread: TMDSCNCD28388D

Tool/software:

I am currently working with TMDSCNCD28388D and I got a problem while upload a code. It seems debugger causes the problem. 
I am using USB560 v2 System Trace (BH-USB-560v2) and I have a problem with it's booting.
When I connect it to a power, it shows RED on the USB Status LED and Blink Green on the MODE Status LED.
The user guide says the MODE Status LED will be turned into solid green when the boot cycle is completed and it used to take ~20 seconds, however, mine doesn't show solid green ever.
Briefly, I am stucking in this situation:
- RED on USB Status LED
- Blink Green on MODE Status LED

I am confusing cuz the above behaviour isn't described on the user guide. I purchased the debugger just few months ago and suddenly it won't work. 

What's wrong with my debugger and how can i solve it? A/S is the only solution?

Kind regards,
