Has anyone figured out how to overvolt yet?  I see this in the gridseed driver...

typedef struct s_gridseed_info {
   enum sub_ident   ident;
   uint32_t   fw_version;
   struct timeval   scanhash_time;
   int      nonce_count[8];  // per chip
   int      error_count[8];  // per chip
   // options
   int      baud;
   int      freq;
   unsigned char   freq_cmd[8];
   int      chips; //chips per module
   int      voltage;
   int      per_chip_stats;
}
Aand later on this method:

static void gc3355_increase_voltage(struct cgpu_info *gridseed) {
   uint32_t reg_value;

   // Put GPIOA pin 5 into general function, 50 MHz output.
   if (!gc3355_read_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_CRL_OFFSET, ®_value)) {
      applog(LOG_DEBUG, "Failed to read GPIOA CRL register from %i", gridseed->device_id);
      return;
   }
   reg_value = (reg_value & 0xff0fffff) | 0x00300000;
   if (!gc3355_write_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_CRL_OFFSET, reg_value)) {
      applog(LOG_DEBUG, "Failed to write GPIOA CRL register from %i", gridseed->device_id);
      return;
   }

   // Set GPIOA pin 5 high.
   if (!gc3355_read_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_ODR_OFFSET, ®_value)) {
      applog(LOG_DEBUG, "Failed to read GPIOA ODR register from %i", gridseed->device_id);
      return;
   }
   reg_value |= 0x00000020;
   //reg_value &= 0xFFFFFFDF;
   if (!gc3355_write_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_ODR_OFFSET, reg_value)) {
      applog(LOG_DEBUG, "Failed to write GPIOA ODR register from %i", gridseed->device_id);
      return;
   }
}

Looks to me like we pass an int as the argument voltage and it will add it to the base voltage value(which i think is set to 0, if I'm reading the header right), maybe?  But then it also says gpio(general purpose input output?), which is usually a general purpose pin header on the pcb itself, right?  I'm no developer/hardware engineer, anyone want to comment?

Probably too expensive but here is a 49 port designed for continuous enterprise use:

Do you know of any hubs that keep all the ports on a single level?  I already purchased and installed a 2nd RaspPi and have 20 miners on each, but in the future it might be helpful for others that want to control more from a single unit (which I bet it can since 20 miners only results in around 10% utilization).

My gridseed miner uses ST32 Virtual COM Port, and at the moment cgminer-3.7.2 doesn't detect the device. I've updated its driver by zadig, but still no luck. What is the solution to this?

Thanks, I will start working on a raspberry pi setup later this evening. Most of the setup guides I have read say 10 miners with a pi. Any tried a pi with say 40 miners?  

I posted this in another thread and did not get a response. Are some of the control units being sent out with a virus? I bought this one from atari02. It seems to be hashing okay in the wiibox but does not always show up as hashing in scryptguild.

Original message:
I had root access with SSH and overclocked the controller. Then, I upgraded to 2.0.4 and I lost root access. The password no longer works. I upgraded to 2.0.5 and still get 'access denied'. Could the controller have been hacked somehow?

ok, lol ... I got a f... problem ... somehow my controller is getting hijacked ...

... ... I haven't changed anything then upgrading to wiibox 2.0.2 ... that's it ...

user and psw is getting changed to ... a users miner ... called wwee.1, wwee.2 ...

... I already mentioned that on my controller .... that I received ... there was malicious code ...

that turned pool, user & worker .... to a thrid party in my absence ....

I haven't changed ... anything at the code, except upgrading with wiibox.net to 2.0.2 ...


Has someone a similar issue with a wiibox controller ?

my work around im not using that controller for the moment ...
