I get "failed usb_init" for 2 devices. Reinstalled drivers, unplugged - same message. The ones that give me this message are hot. Are they dead?


Edit: running cgminer.exe -n shows me all devices. What now?

Anyone?

The ones that give me this message are hot.

Are there other ones running? If yes, it can´t be the drivers.
Tried to run them with 100 MHz? That helps sometimes to reinitialize them.
Where do you get the message? Is it inside the running cgminer?

[sidehack]

If they're hot, it could be the voltage is cranked up too high and the hub ports crap out when the chips try to initialize.

[der_wasi]

I just set up my voltage on both sticks slightly above 1,5 V. Starting with 100 MHz until 200 MHz works fine.
At 225 MHz one works and one goes zombie after a short time.
At above 250 MHz I get this right after starting:

Is this a power issue? The voltage to set is the total string voltage, right?
I have a 30 W power supplied hub. That would be 6 A at 5 V. So three A per stick. The table on post#1 says 2.8 A at 1,5 V and 300 MHz. So it should be enough power, right?

[sidehack]

Should be, unless your hub's wiring is lousy and the voltage is dropping out. Consider some of the other first-post charts; 1.5V is way the heck high for any frequency you're wanting to run. At 250MHz 1.4V should be about enough, and only 2A. Are you able to check your USB port's 5V actual voltage under load?

[der_wasi]

I have set them to 1.36 V now and they are both running with 250 MHz.
The Voltage on the usb port is 4.99 V. If they run stable now I´m fine with it. I just thougt I coul run them both with maximum of 300 MHz with this hub.
Maybe I bouy another some time.

[sunk818]

Turning off the USB hub is electrically equivalent to unplugging and replugging.

Just realized with the Unpluggable USB HUB. If you power it off, it doesn't turn back on automatically. You have to push the power button. WTF? Timer is useless in this situation because once you power it off, the USB HUB will not power back on even when the timer is turned ON.

Are you getting any HW at 250mhz/1.36v?

[KILLInUrSQUAD]

just curious if some one wouldn't mind pasting their conf file to set these at a higher freq..
the example did not come with my version of cg miner but i managed to find one for it and am not sure how to adjust freq....
need a copy and paste ordeal so i can just change the pool info and set the freq to what i want it to be
thank you in advance

[sidehack]

Someone posted a sample config file on here four days ago. It's on the previous page.

[der_wasi]

No they run perfectly. It occurs sometimes that my pi freezes. But it did that before either.

@KILLInUrSQUAD:

Code:

{
"pools" : [
        {
                "url" : "stratum+tcp://connect.pool.bitcoin.com:3333",
                "user" : "USERNAME",
                "pass" : "PASSWORD"
        }
],
"gekko-2pac-freq" : "250.0"
}

Where do you get the message? Is it inside the running cgminer?

I got a total of 3. 2 aren't running at all and they are hot when they are simply in the USB slot and 1 is running, but cgminer sees it as COMPAC-2 and after running for 1-2 minutes I get a message saying "Dup nonce". Also cgminer seems to set the frequency weird. I see a line with the following message that I haven't seen before "GSD 0: set frequency: 100.00 [07 03]" on the one that is running.

But when running cgminer.exe -n I can see all 3 as 2Pac products. Isn't it weird?

If they're hot, it could be the voltage is cranked up too high and the hub ports crap out when the chips try to initialize.

They are hot, but I haven't touched the voltage and I never ran them higher than 100MHz.

When I'm running cgminer with "--gekko-2pac-freq 100" argument I get the "failed usb_init" message and then "No devices detected!", but the device is visible when running cgminer -n.

[sidehack]

Just because you haven't adjusted the voltage doesn't mean that it's still set to stock values - in which case what I said still definitely could apply. The logical next step, then, is to try adjusting the voltage instead of doing nothing. Have you looked at the troubleshooting suggestions in the first post?

[RoadStress]

Found the problem. The cgminer build.

[Satiasha]

Just kinda wondering why the cgminer compile for windows and specifically the gekko compiled one has a virus attached, i had to disable windows defender multiple times, plus add exclusions to avoid it being deleted. Being new to using the 2pac, I even had to use Firefox to download it as chrome flagged it as well.

[sidehack]

Asked and answered half a dozen times. False positive because scammers something something botnet something cgminer back in the day and antivirus software is lazy/paranoid.

[Satiasha]

I've been reading the forum for the past 2 days probably skimmed right over it without noticing. Just more of an annoyance per say with windows defender at that point, but switching over to another computer with Ubuntu soon since I was able to get it complied and working.

Hi.

I have a problem getting my stickminer to work. The same thing happens all the time. The miner blinks two times with a white light (The green light is always on). Then I get the attached
message. Any ide what I can try to do?

I dont know how to add a picture here. But it says: "Failed to open Device Parameters registry key in lowl-vcom.c _vcom_devinfo_scan_windows_hubport():556:System can not find the file

I haven't seen that particular error, but if you read and follow along the first post's run instructions, there's a decent chance you won't end up at this specific error.
