Have the same problem:
Avalon 55nm 230Ghs
TP-link 703N
0 hash at all. network is OK
Tried both OpenWrt and direct USB (cgminer).
LED:
Done - constantly lit
1 led - blink
Tried everything - all firmware of Tplink, several Wifi routers (messed up with Connection refused).
cgminer shows
Avalon: Reset failed! not an Avalon? (0: 00 b6 b2 10)
get avalon read got err 0

Upgrade from ancient firmware

Was this ever resolved? I'm running into the same issue with a unit I just bought.

I am not sure what LED1 ~ LED4 are doing for. Normally they are off, if the ctrl u is working properly. So I think this ctrl unit should be working properly as well.
Try upgrade the firmware in your 703n to the newest version (0723 I think). That the last thing I can suggest at this moment.

When the control unit is working, is the LED labeled as "Done" on? Besides it, are there any other LEDs (LED1 ~ LED4) on at the same time?
Yes, DONE is instantly lit after power is turned on.No, the other LEDs are dark.
I know the DONE LED is for the FPGA, do you actually know what the other one are for?

The FTDI chips should be working, in my point of view. The problem maybe some internal error in the FPGA. If you have the right tools you can try to re-flash it.

could you please ssh to tplink 703n, run command "dmesg | grep usb" and show the output here.
Here you go:

No -- "Err 0" is result value for success (i.e. no error). You can see this if you look at cgminer code.
Yes, you are right... Somehow redundant to display this message for "no error". Anyway, the unit is not producing a single valid share.
Hooking it up to a Xubuntu machine, cgminer says "Idling 32 miners" and nothing happens.
Using the TP-Link and starting cgminer via SSH:
Code:
root@OpenWrt:~# cgminer --avalon-options 115200:24:10:45:282 -S/dev/ttyUSB0 -o [redacted] --api-allow
W:127.0.0.1 --api-listen --quiet

@Ytterbium
Yes, but then I still don't know
- If the board is actually broken or there's something that can easily be fixed
- What caused this error (so I can avoid it in the future, if I did something wrong)
@coldguy
Thanks, I will do that tomorrow.

Have you gotten in contact with the company that made the clone? Maybe they can send replacement controller board.

Hi,
I have an Avalon (clone) here which worked for some time but now stopped doing so. Cgminer output is: http://pastebin.com/YeAPkPWP (Too long to paste it in this post)
To me it looks like there is some problem with the USB interface, like it cannot read from it. Is it possible the FTDI chip is broken? (If yes, how could that happen?)
(I tried to attach the control unit to the TP-Link router as well as to a Xubuntu machine (which generated the output above), same result)
Thanks for any suggestions!
