I'm using 4 of 2pac stick. It work well when I connect only one. But connect 2 or 3 stick, there is crash. GSD 4 : No valid hashes recently, attempting to reset GSD 4 attempted reset got err:(0) LIBUSB_SUCCESSI add screenshot. https://i.imgur.com/bhqNIrl.pngDo I need to do something to use multiple 2pac stick? Thank for your helping.

You probably need a better hub.

I need Help . I'm on the step when I supposed to compile a final command (it's when i enter gekkoscience 2pac ,user name password, pool and worker I think ) I'm looking for example specifically for 2Pac , I am using raspbien . I would gladly appreciate help. Thanks.

The run syntax is at the beginning of the How to Run section of the first post. You can copy and paste it as is to make sure it works, then adjust the pool, user, and pass as needed.

Nothing special to do. Plug it in. If there is enough power, both sticks will start. If you swap them and they both work by themselves, you will need to find a [good] powered hub. Re-read the first post for details.

I'm on the lookout for old usb miners in the sub-$40 range (USA) to do some local regression testing before submitting this cgminer fork back to the main chain. If you have some laying around collecting dust that you want to sell, offload or contribute for testing, PM me. Looking for one of each (anything usb cgminer) that still works. The Compac(s) and 2Pac look very lonely on this hub at the moment. Hopefully that will be remedied not too long from now.

That's a pretty nice looking hub. I think at one point Sidehack was thinking about making hubs to sell, did that project ever go anywhere? Sorry. the only sha256 miner I've got is one of your 2pacs. But I'm using your cgminer on it.

I've got prototype PCBs sitting on a shelf I haven't had time to work on. Proper functionality will require some microcontroller code and I've been elbow-deep in manufacture all year. I just last Thursday made time to finish the Terminus pod redesign that I had rough-prototyped in late April. The hub will happen, just not in the short term. That idea was originally conceived two years ago anyways.

is it possible to specify different frequency for each device?
Example 2 devices (2pac bm1384) 1 wtih 230 and another with 300 mhz on the same pool with same worker?

You can target cgminer to a specific device. run ./cgminer -n to get a list of devices if you get: .USB dev 3: Bus 1 Device 11 ID: 10c4:ea60 Manufacturer: 'GekkoScience' Product: '2Pac BM1384 Bitcoin Miner' .USB dev 3: Bus 1 Device 12 ID: 10c4:ea60 Manufacturer: 'GekkoScience' Product: '2Pac BM1384 Bitcoin Miner' you can target the first device by using --gekko-2pac-freq 230 --usb 1:11 for the second run of cgminer --gekko-2pac-freq 300 --usb 1:12

Long time reader, first time poster here. I just wanted to say thank you to everybody for all the amazing information that I find here. Right now I am running CGMINER VERSION 4.10.0 on a Raspberry Pi3. I have four Gekko 2Pacs running perfectly with their frequency set at 250. My average hash rate is 112 Gh/s. I have my 2pacs running through a Superpbag USB hub, and have had no issues since making sure the sticks were getting the right amount of power. A lot of trial and error, other USB hubs, USB y connectors etc. But the Superbpag has had a perfect run with the four sticks. I have multiple fans cooling them with some extra added heat sinks.
I got the 2pacs and had minimal experience with Linux. The help here made it easy to get it up and running and the guys running the show are very skilled and knowledgeable. The students in my classroom have become awesome at researching and learning from all of you. Their confidence has been building and they have no fear of working with hardware and software. I truly appreciate all the help and guidance here. Very informative and professional!
Sometimes we do have little issues here and there, but all seem to be easily resolved with the support and help here.
Sorry for the random post. I just was doing my daily read of the forum and wanted to chime in and say thanks to all!

The BM1385 datasheet has good protocol info. Not quite everything you need, but close. VH and I spent a day or two sniffing HEX and parsing kernel logs to figure out a few specifics, especially for multi-chip detection and nonce range assignment, but for single-chip comms I think everything's there.
The Compac and 2Pac, since they use a CP2102 USB-UART adapter, can actually be driven straight from a terminal if you figure out the formats.

I think you have a near identical setup to myself, but you're clearly a bit further along this rabbit hole than myself. I'm running two 2Pacs through the Superpbag 7 Port USB hub. I currently have them at 225 and I think that's about where I'll leave them. I may even dial them back a bit. I'm trying to figure out if they are running too hot at 225 with the fan I have on them. Out of curiosity, where did you put the extra heatsinks?
